$test_array = array('id' => 1, 'nom' => 'Onche');
$start = microtime(true);
//for + extract()
for ($i = 0; $i < 100000; $i++):
extract($test_array, EXTR_OVERWRITE);
endfor;
$end = microtime(true);
$time = $end - $start;
var_dump($time); // 0.14039993286133
// for
$start = microtime(true);
for ($i = 0; $i < 100000; $i++):
$id = $test_array['id'];
$nom = $test_array['nom'];
endfor;
$end = microtime(true);
$time = $end - $start;
var_dump($time); // 0.031199932098389
//for + foreach
