• sql_regcase -
This function converts each alphabetical character into its equivalent lower and upper
case representation surrounded by brackets. For those characters that are not alphabetical, no change
is taken place.
<?php
$text = "MySQL's website is http://www.mysql.com";
print sql_regcase($text);
// Outputs [Mm][Yy][Ss][Qq][Ll]'[Ss] [Ww][Ee][Bb][Ss][Ii][Tt]
// [Ee] [Ii][Ss] [Hh][Tt][Tt][Pp]://[Ww][Ww][Ww].[Mm][Yy][Ss]
// [Qq][Ll].[Cc][Oo][Mm]
