isset($var) vs. @$var

Question

Is this an okay practice or an acceptable way to use PHP\'s error suppressing?

if (isset($_REQUEST[\'id\']) && $_REQUEST[\'id\'] == 6) {
  echo \'hi\         


        

Answer 1

Suppressing the errors using @ only suppresses the display of the error, not the creation. So you get a small performance hit from the error if you don't check isset() first.
