sql_regcase --  Make regular expression for case insensitive match


string sql_regcase (string string)

Returns a valid regular expression which will match string, ignoring case. This expression is string with each character converted to a bracket expression; this bracket expression contains that character's uppercase and lowercase form if applicable, otherwise it contains the original character twice.

Example 1. Sql_regcase() Example

echo sql_regcase ("Foo bar");
[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.
