<?php /*
Defines a subset of parser functions that operate on strings.
{{#sub:value|start|length}} Returns a substring of the given value with the given starting position and length. If length is omitted, this returns the rest of the string. http://php.net/manual/en/function.substr.php {{#pos:value|key|offset}} Returns the first position of key inside value, or nothing. If offset is defined, this method will not search the first offset characters. Note: key may not exceed 30 characters in length. http://php.net/manual/en/function.strpos.php {{#len:value}} Returns the length of the given value. http://php.net/manual/en/function.strlen.php {{#urlencode:value}} URL-encodes the given value. http://php.net/manual/en/function.urlencode.php {{#urldecode:value}} URL-decodes the given value. http://php.net/manual/en/function.urldecode.php Author: Algorithm [1] Version 1.2.1 5/19/06
