    Warning

    This function was DEPRECATED in PHP 5.3.0, and REMOVED in PHP 7.0.0.

    Description

    string sql_regcase ( string $string )

    Creates a regular expression for a case insensitive match.

    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.

    if you set right locale:

    setlocale(LC_CTYPE,"ru_RU.KOI8-R");

    print sql_regcase("Цffnung");

    will output:
    "[Цц][Ff][Ff][Nn][Uu][Nn][Gg]"

    This function naivley replaces the letters in your expression.
    if your expression uses [] already using this will probably break it
