[PHP] Regexp and Arrays

[Allen McCabe]

I have been plauged for a few days by this, can anyone see a problem with
this function??

function printByType($string, $mode)
 {
  (string) $string;
  $lengths = array(
    'VARCHAR' => 10
    , 'TINYINT' => 1
    , 'TEXT' => 10
    , 'DATE' => 7
    , 'SMALLINT' => 1
    , 'MEDIUMINT' => 2
    , 'INT' => 2
    , 'BIGINT' => 3
    , 'FLOAT' => 4
    , 'DOUBLE' => 4
    , 'DECIMAL' => 4
    , 'DATETIME' => 10
    , 'TIMESTAMP' => 10
    , 'TIME' => 7
    , 'YEAR' => 4
    , 'CHAR' => 7
    , 'TINYBLOB' => 10
    , 'TINYTEXT' => 10
    , 'BLOB' => 10
    , 'MEDIUMBLOB' => 10
    , 'MEDIUMTEXT' => 10
    , 'LONGBLOB' => 10
    , 'LONGTEXT' => 10
    , 'ENUM' => 5
    , 'SET' => 5
    , 'BIT' => 2
    , 'BOOL' => 1
    , 'BINARY' => 10
    , 'VARBINARY' => 10);
  $types = array(
    'VARCHAR' => 'text'
    , 'TINYINT' => 'text'
    , 'TEXT' => 'textarea'
    , 'DATE' => 'text'
    , 'SMALLINT' => 'text'

     (int) $val;

     // DETERMINE LENGTH VALUE eg. int(6) GETS 6
     preg_match('#\((.*?)\)#', $string, $match);
     (int) $length_value = $match[1];

     // SEARCH
     $regex = "/" . strtolower($key) . "/i";
