sql_regcase — Make regular expression for case insensitive match
Creates a regular expression for a case insensitive match.
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
The input 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
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.
