supressing errors is really slow

Benchmarks on the error_reporting solution

Code:

$end = 1000;
        $this->benchmark->mark('dog');
        for($i=0;$i<$end;$i++)
        {
            $value = @$_POST['test'];
        }
        $this->benchmark->mark('cat');
        for($i=0;$i<$end;$i++)
        {
            error_reporting(0);
            $value = $_POST['test'];
            error_reporting(E_ALL);
        }
        $this->benchmark->mark('bird');
        
        echo '@ time : '.$this->benchmark->elapsed_time('dog', 'cat').'<br>';
        echo 'error_reporting time: '.$this->benchmark->elapsed_time('cat', 'bird').'<br>';

1 time result
@ time : 0.0001
error_reporting time: 0.0000

10 times result
@ time : 0.0003
error_reporting time: 0.0003

100 times result
@ time : 0.0022
error_reporting time: 0.0027

1000 times result
@ time : 0.0222
error_reporting time: 0.0266

so that's even worse than suppressing errors.
