# sql_regcase

(PHP 3, PHP 4, PHP 5)

sql_regcase -- Make regular expression for case insensitive match

## Description

string sql_regcase ( string string )

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.

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.
