<?php /*

Defines a subset of parser functions that operate on strings.

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

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

Returns the length of the given value. http://php.net/manual/en/function.strlen.php

URL-encodes the given value. http://php.net/manual/en/function.urlencode.php

URL-decodes the given value. http://php.net/manual/en/function.urldecode.php
