Bonjour tlm, y a til un moyen de multiplier les valeures de 2 tableaus de meme nature :
merci

Est-ce qu'une solution à base de foreach te conviendrait ?

<?php
// affectation
$total_1= array("01" => 1,"02" => 0,"03" => 2,"04" => 0);
$total_2= array("01" => 3,"02" => 5,"03" => 2,"04" => 0); 
// multiplication (resultat dans $total_3)
foreach($total_1 as $key => $val) {
	$total_3[$key]=$total_1[$key]*$total_2[$key];
}
// verification
foreach($total_3 as $key => $val) {
	echo "<BR>".$key." -> ".$val;
}

?>

proposition avec array_map()

function mult($a, $b) 
{
    return $a * $b;
}  

$total_1= array("01" => 1,"02" => 2,"03" => 2,"04" => 0);

$total_2= array("01" => 3,"02" => 5,"03" => 2,"04" => 0);     
 
$c = array_map("mult", $total_1, $total_2);
print_r($c);
