如何在$ _POST中使用变量[...]

Question

That's my code:

for($zm=1; $zm<=$ilosc; $zm++){
$aaa.$zm = $_POST['bbb.$zm'];
}

I want to use variable

$zm in $_POST --> ( $_POST['bbb.$zm'] );

What is the proper form?

Answer 1

Try :

$var = "aaa".$zm;
$$var =  $_POST["bbb".$zm];

OR :

$var = "aaa".$zm;
$$var = $_POST["bbb{$zm}"];

its called variable variables .
