In all the years I have been developing in PHP, I have always heard that using
eval() is evil.
Considering the following code, wouldn't it make sense to use the second (and more elegant) option? If not, why?
// $type is the result of an SQL statement, e.g. // SHOW COLUMNS FROM a_table LIKE 'a_column'; // hence you can be pretty sure about the consistency // of your string. $type = "enum('a','b','c')"; // option one $type_1 = preg_replace('#^enum\s*\(\s*\'|\'\s*\)\s*$#', '', $type); $result = preg_split('#\'\s*,\s*\'#', $type_1); // option two eval('$result = '.preg_replace('#^enum#','array', $type).';');
