Benchmark or time script

Here is a little example of how to benchmark or time something with php

<?php

// a function to get microtime
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}

// start time
$time_start = getmicrotime();

// a little loop to time
for ($i=0; $i < 10000; $i++)
{
// print the loop number
echo $i.'<br />';
}

// the end time
$time_end = getmicrotime();

// subtract the start time from the end time to get the time taken
$time = $time_end - $time_start;

// echo a little message
echo '<br />Script ran for ' . round($time,2) .' seconds.';

?>

This will produce a list of numbers from 0 to 9999 in your browser and tell you how long it took too complete the iterations.

PHP Function Number to Roman and Roman to Number

class konversi{
function roman2number($roman){
$conv = array(
array("letter" => 'I', "number" => 1),
array("letter" => 'V', "number" => 5),
array("letter" => 'X', "number" => 10),
array("letter" => 'L', "number" => 50),
array("letter" => 'C', "number" => 100),
array("letter" => 'D', "number" => 500),
array("letter" => 'M', "number" => 1000),
array("letter" => 0, "number" => 0)
);
$arabic = 0;
$state = 0;
$sidx = 0;
$len = strlen($roman);

while ($len >= 0) {
$i = 0;
$sidx = $len;

while ($conv[$i]['number'] > 0) {
if (strtoupper($roman[$sidx]) == $conv[$i]['letter']) {
if ($state > $conv[$i]['number']) {
$arabic -= $conv[$i]['number'];
} else {
$arabic += $conv[$i]['number'];
$state = $conv[$i]['number'];
}
}
$i++;
}

$len--;
}

return($arabic);
}

function number2roman($num,$isUpper=true) {
$n = intval($num);
$res = '';

/*** roman_numerals array ***/
$roman_numerals = array(
'M' => 1000,
'CM' => 900,
'D' => 500,
'CD' => 400,
'C' => 100,
'XC' => 90,
'L' => 50,
'XL' => 40,
'X' => 10,
'IX' => 9,
'V' => 5,
'IV' => 4,
'I' => 1);

foreach ($roman_numerals as $roman => $number)
{
/*** divide to get matches ***/
$matches = intval($n / $number);

/*** assign the roman char * $matches ***/
$res .= str_repeat($roman, $matches);

/*** substract from the number ***/
$n = $n % $number;
}

/*** return the res ***/
if($isUpper) return $res;
else return strtolower($res);
}
}

PHP Substr In Array

To find if a value exists in an array, the PHP in_array() function works quite nicely. But there are times when only a partial match is required to check in the array. This substr_in_array() function checks will search the values of an array for a substring. The $needl can be a string or an array of strings to search for.

<?php
/**
*
* @Search for substring in an array
*
* @param string $neele
*
* @param mixed $haystack
*
* @return bool
*
*/
function substr_in_array($needle, $haystack)
{
/*** cast to array ***/
$needle = (array) $needle;

/*** map with preg_quote ***/
$needle = array_map('preg_quote', $needle);

/*** loop of the array to get the search pattern ***/
foreach ($needle as $pattern)
{
if (count(preg_grep("/$pattern/", $haystack)) > 0)
return true;
}
/*** if it is not found ***/
return false;
}
?>

Example Usage

<?php

/*** an arrray to search through ***/
$array = array('dingo', 'wombat', 'kangaroo', 'platypus');

/*** an array of values to search for ***/
$strings = array('foo', 'bar', 'kang');

/*** check for true or false with ternary ***/
echo substr_in_array( $strings, $array ) ? 'found' : 'not found';

/*** a single string to search for ***/
$string = 'plat';

/*** check for true or false with ternary ***/
echo substr_in_array( $string, $array ) ? 'found' : 'not found';
?>

The Complete Reference for Any jQuery Developer

To make optimal use of jQuery, it's good to keep in mind the breadth of capabilities it provides. You can add dynamic, interactive elements to your sites with reduced development time using jQuery. If you are looking for a comprehensive reference guide to this popular JavaScript library, this book is for you.

Revised and updated for version 1.4 of jQuery, this book offers an organized menu of every jQuery method, function, and selector. Each method and function is introduced with a summary of its syntax and a list of its parameters and return value, followed by a discussion, with examples where applicable, to assist in getting the most out of jQuery and avoiding the pitfalls commonly associated with JavaScript and other client-side languages.

In this book you will be provided information about the latest features of jQuery that include Sizzle Selector, Native event delegation, Event triggering, DOM manipulation, and many more. You won't be confined to built-in functionality, you'll be able to examine jQuery's plug-in architecture and we discuss both how to use plug-ins and how to write your own. If you're already familiar with JavaScript programming, this book will help you dive right into advanced jQuery concepts. You'll be able to experiment on your own, trusting the pages of this book to provide information on the intricacies of the library, where and when you need it.

Check username availability in ajax and php using jquery’s

Now let’s check it how to do check the username avaiability in ajax and php using jQuery.

Html Code :


<div>
User Name : <input name="username" id="username" value="" maxlength="15" type="text">
<span id="msgbox" style="display: none;"></span>
</div>

As you can see the above the “span” with id “msgbox” will show you the username availability message from ajax.

Css code :


.messagebox{
position:absolute;
width:100px;
margin-left:30px;
border:1px solid #c93;
background:#ffc;
padding:3px;
}
.messageboxok{
position:absolute;
width:auto;
margin-left:30px;
border:1px solid #349534;
background:#C9FFCA;
padding:3px;
font-weight:bold;
color:#008000;
}
.messageboxerror{
position:absolute;
width:auto;
margin-left:30px;
border:1px solid #CC0000;
background:#F7CBCA;
padding:3px;
font-weight:bold;
color:#CC0000;
}

I’ve defined three different class for three type of different message class “messagebox” for “checking….” message, “messageboxok” and “messageboxerror” class for displaying username available and not available messages.

As you know you can change the attriubutes of the css of the above code but keep in mind that “position” property should be “absolute”.

Javascript code :

First of all, the jQuery library is used,


<script src="jquery.js" type="text/javascript" language="javascript"></script>

As you can see in the first line, “all” css class is removed from the div displaying the message and then “messagebox” class is added to that that element with adding the text “checking” within the element and displaying with fading effect.


$("#username").blur(function()
{
//remove all the class add the messagebox classes and start fading
$("#msgbox").removeClass().addClass('messagebox').text('Checking...').fadeIn("slow");
//check the username exists or not from ajax
$.post("user_availability.php",{ user_name:$(this).val() } ,function(data)
{
if(data=='no') //if username not avaiable
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('This User name Already exists').addClass('messageboxerror').fadeTo(900,1);
});
}
else
{
$("#msgbox").fadeTo(200,0.1,function()  //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Username available to register').addClass('messageboxok').fadeTo(900,1);
});
}
});
});

After that, ajax is used to call the PHP file, and when response is received through Ajax then jQuery is used to show the respective message-box with fading effects.

Php Code:


//this varible contains the array of existing users
$existing_users=array('roshan','mike','jason');
//value got from the get metho
$user_name=$_POST['user_name'];
//checking weather user exists or not in $existing_users array
if (in_array($user_name, $existing_users))
{
//user name is not available
echo "no";
}
else
{
//username available i.e. user name doesn't exists in array
echo "yes";
}

In the above PHP code, I’ve added three usernames in a array and then check weather that user exists or not in that array and print “yes” or “no” accordingly. The response taken from ajax is used within JavaScript function to display the appropriate message.But, you can use database connection to check the the availability of username in your code.

PHP > Sample Class Login with secure session

This class can be used to prevent security attacks known as session hijacking and session fixation.

When a session is initialized the class computes a fingerprint string that takes in account the browser user agent string, the user agent IP address or part of it and a secret word. If the fingerprint value changes, it is very likely that the session was hijacked and it should no longer be accepted.

To prevent session fixation attacks the calls the PHP session_regenerate_id() function so the session identifier changes everytime the session is checked.

PHP > Sample Guest Book With Spam Filter

This class can automatically classify text messages to determine whether or not their are considered to be spam.

It can build a knowledge base of known text expressions that can be looked up later to evaluate a factor that expresses the probability of a given text to be spam.

This class could be used in Web mail applications or even in less obvious applications like forums and guest books, acting like an semi-automatic moderator.

Other Popular Guestbooks
This method takes all of the POST content, creates a single string, and runs it through SLV. It also removes your host name from the input in case you are passing on a variable such as a thank you page. I have implemented it on several popular guestbooks. I have not tested the code though, it may need some tweaks.

Sample 3D Programming With VB

If you want to take part in one of the most incredible computer gaming experiences available, Genesis Entertainment L.C. is currently working on Realms of Time, a state-of-the-art RPG designed to revolutionize the gaming world. If you or anyone you know has experience in C++ or excellent skills in VB graphic or text programming, or if you just want to hear the details of this incredible project, contact me at the e-mail address listed below. Beta testers will be needed at some point in the future (NOT NOW, though, so don't ask for now!), so if you want to be on the list of candidates, contact me with a PROFESSIONAL resume detailing your experience.

Also, and most importantly, we are looking for a talented 3D Graphics designer to help us with the many characters, both human and non-human, that will be needed for our game. We are currently working on producing our own, but because our immediate focus is on scripting out the details of the storyline and building peripheral programs (like the map, magic, item, and character editors), we don't have a lot of time to spend on our graphics. We are specifically looking for two types of 3D Graphics - characters (humans, monsters, etc.) that are similar to the style of Diablo characters (i.e. very nicely done at a small size, so huge amounts of close-up details aren't necessary), and 3D CG movies (we are aiming for CG graphics similar to those in Final Fantasy 7, and hopefully Final Fantasy 8, although those kind of graphics are most likely far out of our (or anyone but SquareSoft's) reach) with the same creatures mentioned above, except life-size and totally realistic. If you or anyone you know may be interested, contact the Realms of Time production team at realmsoftime@usa.net.

Sample HTML Help and Visual Basic 6 - Tutorial

When you distribute an application, there should be some guidance for your customers and/or users how to work with it. You can simply add a few HTML pages, but this will not allow you to use the often appreciated "what's this help", in form of the small question mark in your applications form borders. Neither does it look professional.

The purpose of this document/tutorial is showing you how to use HTML Help for a very simple help file, and how to 'attach' it to your application. Note that by no means this document has been written to teach you everything about HTML Help. This document focuses more on the actual help file, combined with your Visual Basic 6 application.

Using PHP scripts to send an email

What is PHP?
PHP, which stands for "Hypertext Preprocessor", is a server-side, HTML embedded scripting language used to create dynamic Web pages. Much of its syntax is borrowed from C, Java and Perl with some unique features thrown in. The goal of the language is to allow Web developers to write dynamically generated pages quickly.

In an HTML page, PHP code is enclosed within special PHP tags. When a visitor opens the page, the server processes the PHP code and then sends the output (not the PHP code itself) to the visitor's browser. It means that, unlike JavaScript, you don't have to worry that someone can steal your PHP script.

PHP offers excellent connectivity to many databases including MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, and Generic ODBC. The popular PHP-MySQL combination (both are open-source products) is available on almost every UNIX host. Being web-oriented, PHP also contains all the functions to do things on the Internet - connecting to remote servers, checking email via POP3 or IMAP, url encoding, setting cookies, redirecting, etc.

Basic Syntax

* File name:
You should save your file with the extension .php (earlier versions used the extensions .php3 and .phtml).
* Comments:
// This comment extends to the end of the line.
/* This is a
multi-line
comment */
* Escaping from HTML:
A PHP code block starts with <?php" and ends with "?>. A PHP code block can be placed anywhere in the HTML document.
* Instruction separation:
Each separate instruction must end with a semicolon. The PHP closing tag (?>) also implies the end of the instruction.

This tip provides information on use of utility Command line email client in PHP script. Use of standard PHP mail() function which allows you to send mail, is very complicated. By using febooti Command line email you can:

Send email message using plain text or HTML message with embedded pictures.
Send unlimited number of attachments.
Use return codes to check success or failure.
Works on Microsoft Windows (98 / Me / NT / 2000 / 2003 / XP / Vista) including all server versions.
And many more options...

Sample PHP script:

/**** febootimail PHP email ****/
<?php
// Send e-mail from PHP and output the result.
// (On a MS Window operating system with
// the "febootimail.exe" executable in the path).

$server=' -SMTP smtp.sender.com -PORT 25';

$body='"This is <I>HTML / MIME</I> e-mail message"';
$body.='" sent with <B>febooti Command line email</B>"';

$subj='PHP mail';

$command='febootimail.exe -HTML -MIME -FROM web@sender.com ';
$command.='-TO john@sender.com '.$body.$server;
$command.='-SUBJ '.$subj.' -BODY '.$body.$server;

$result=0;

exec($command,$output,$result);
echo 'Output: ';
print_r($output);
echo '<BR>';
echo 'Result: '.$result;

// For detailed information about result codes, see:
// Utility Command line email client with MS-DOS batch files - returned errorlevels
?>
