PHP API Header For Function Libraray (Call Any PHP Functions Via Ajax)
Place your functions below the header and then call them by posting to the script with any kind of ajax : $('#test').load('base/ajax/ajaxapi.php',{method:'sha256',params:"'batman','gargamelhatessmurfs'"}); for example.
/**

Want to be able to display the source code of any webpage, with line numbering? Here is a simple code snippet to do it. Just modify the url on line 2 at your convenience. Or even better, make a pretty function according to your needs.

Get Whois Information.

If you need to get the whois information for a specific domain, why not using PHP to do it? The following function take a domain name as a parameter, and then display the whois info related to the domain.
function whois_query($domain) {
// fix the domain name:
$domain = strtolower(trim($domain));
$domain = preg_replace('/^http:\/\//i', '', $domain);
$domain = preg_replace('/^www\./i', '', $domain);
$domain = explode('/', $domain);
$domain = trim($domain[0]);
// split the TLD from domain name
$_domain = explode('.', $domain);

PHP - Generating Emoticons
URL: http://www.flashstar.nl/article-37.html
If you are a PHP developer, you are probably aware that you can pass an array of strings as the search strings and an array as the replacements to the str_replace function. In this example you can see how to automatically replace smiley shortcuts by an image.
<?php
function emoticons($text) {
$emoticons = array(
'<img src="images/smiley-happy.png" alt="emoticon" />' => array('1' => ':-)', '2' => ':)'),
'<img src="images/smiley-wink.png" alt="emoticon" />' => array('1' => ';-)', '2' => ';)'),
'<img src="images/smiley-cool.png" alt="emoticon" />' => array('1' => '8)', '2' => '8|')
);
foreach ($emoticons as $key => $emoticon) {
$text = str_replace($emoticon, $key, $text);
}
return $text;
}
echo emoticons('This is :) a text ;-) with :-) emoticons 8)');
?>

PHP Function to Convert 12 Hour Time to 24 Hour Format
Convert 12-hour time format with hour, minutes, seconds, and meridiem into 24-hour format. Performs data correction to make sure hours, minutes and seconds have leading zeros if needed.
The trick here is to use strtotime() where we pass the time string in this format: "hh:mm:ss meridiem" Example: "02:30:00 pm"
<?php
function to_24_hour($hours,$minutes,$seconds,$meridiem){
$hours = sprintf('%02d',(int) $hours);
$minutes = sprintf('%02d',(int) $minutes);
$seconds = sprintf('%02d',(int) $seconds);
$meridiem = (strtolower($meridiem)=='am') ? 'am' : 'pm';
return date('H:i:s', strtotime("{$hours}:{$minutes}:{$seconds} {$meridiem}"));
}
echo to_24_hour( 1, 2, 3, 'pm' ); // Returns 13:02:03
echo to_24_hour( '02', '30', '00', 'pm' ); // Returns 14:30:00

Paginate WordPress Posts
URL: http://www.design-ninja.net
Place the function in your functions.php file of your theme...
Then, simply call like this: wp_paginate('', 3); The first param is optional, the second dictates how many pages before and after the current page link will show...
<?php

if (!$pgs) {
$pgs = 1;
}
}
if (1 != $pgs) {
// echo the HTML output
echo "<div class='wp_paginate'>";
if ($pgd > 2 && $pgd > $rng + 1 && $itm < $pgs)
echo "<a href='" . get_pagenum_link(1) . "'>&laquo;</a>";

Find a file (including subdirectory search)
URL: http://www.visionhive.com
This function searches the current working directory (or any other directory path that you specify with parameter $p) for a file, named $f, and returns the full path and filename of the first occurrence, or false if it is either not found or the maximum number of comparisons is reached. The return value is relative to the executing script, so you can safely pass this function to other file-handling functions, e.g. fopen(FFIND("my.file")); or file(FFIND("my.file"));
function FFIND($f,$p=null,$l=1000)
{ // Recursively find a file $f in directory $p (compare up to $l files)
// Returns the full path of the first occurrence (relative to current directory)
// (c) Peter Mugane Kionga-Kamau http://www.visionhive.com
// Free for unrestricted use with this notice and description unaltered.

Re-create Array Index
If you want to re-index starting to zero, simply do the following:
$iZero = array_values($arr);
If you need it to start at one, then use the following:
$iOne = array_combine(range(1, count($arr)), array_values($arr));
Here are the manual pages for the functions used:
array_values()
array_combine()
range()
