Fatal error: Can't use function return value in write context

Question

Error:

Fatal error: Can't use function return value in write context in /home/u566013465/public_html/2/inc/functions.php on line 2361 line 2361:

if( empty( shell_exec("which $command") ) ) {
    return false;
}

if( $config['debug'] ) {
    $start = microtime(true);
}

I have PHP 5.3

@Rizier123 If you use `return` out side of function, it will exit from current file! — undone, Jan 05 '15 at 19:39

empty function can be used only for variables and if you pass anything else, it will throw a parse error:

$var  = shell_exec("which $command") ;
 if( empty( $var ) ) {
    return false;
}

if( $config['debug'] ) {
    $start = microtime(true);
}
