Array_Map using multiple native callbacks?
Yes, just pass the result of one mapping into another:
$result = array_map( 'mysql_real_escape_string', array_map( 'trim', array_map( 'strtoupper', $your_array ) ));You can also use a callback in PHP 5.3+:
$result = array_map(function($x){ return mysql_real_escape_string(trim(strtoupper($x)));}, $your_array);or earlier (in versions of PHP lower than 5.3):
$result = array_map( create_function('$x','return mysql_real_escape_string(trim(strtoupper($x)));'), $your_array);
