How to create a query list of ID numbers using join from an $array and put into a string that can be used in a MySQL query:

$id_numbers = array(1,6,14,32,84,27,49,77);
$complist = join(”,”, $id_numbers);
$query = “SELECT id from tablename WHERE id IN($complist)”;

substr comes in handy if you need to strip characters off the end of a string.

<?php
$test_string = ‘item 1, item 2, item 3, ‘;
$test_string = substr($test_string,0,-2);
echo($test_string); // returns “item 1, item 2, item 3″
?>

Sooner or later it might become necessary to write an application that tracks site visitor browser types. Here’s some code to use:

?>

Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) 
Mozilla/4.0 (compatible; MSIE 5.0; Mac_PowerPC)
Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
Mozilla/5.0 (Windows; U; Windows NT 5.1; […]

Requirements (also from the sourceforge page):

APIlity works both with PHP4 and […]

string(54) "libcurl/7.13.2 OpenSSL/0.9.7e zlib/1.2.2 libidn/0.5.13"
