表示另一个数组中的数组产品的值

Question

i have an array {

$e = Array ( [0] => 13 [1] => 11 [2] => 2 ) Array ( [989.32] => 13 [77] => 11 [0.99] =>2 );

and i want to multiply each key by their values respectively and use the values to create another array. Anyone know how? i've tried:

foreach($e as $y=>$z)
{$x= $y * $z;
$p=array();
array_push($p,$x);}
print_r($p);

but i got:

Array ( [0] => 1.98 )

Answer 1

One little change in your code:

$p=array();
foreach($e as $y=>$z)
{
$x= $y * $z;
array_push($p,$x);
}
print_r($p);
