(PHP 4, PHP 5)

sql_regcaseMake regular expression for case insensitive match

Description

string sql_regcase ( string $string )

Creates a regular expression for a case insensitive match.

Warning

This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.

Parameters

string

The input string.

Return Values

Returns a valid regular expression which will match string, ignoring case. This expression is string with each alphabetic character converted to a bracket expression; this bracket expression contains that character's uppercase and lowercase form. Other characters remain unchanged.

Examples

Example #1 sql_regcase() example

<?php
echo sql_regcase("Foo - bar.");
?>

The above example will output:

[Ff][Oo][Oo] - [Bb][Aa][Rr].

This can be used to achieve case insensitive pattern matching in products which support only case sensitive regular expressions.

Notes

Note:

As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED notice. See the list of differences for help on converting to PCRE.
