如何在php中将字符串变量转换为数组？

I have one string variable as

$p_list="1,2,3,4";

i want to convert it to an array such as

$a[0]='1';
$a[1]='2';
$a[2]='3';
$a[3]='4';

how to do this in php?

Use explode.

$p_list = "1,2,3,4";
$array = explode(',', $p_list);

See Codepad.

Try explode $a=explode(",","1,2,3,4");

Try this:

In PHP, explode function will convert string to array, If string has certain pattern.

<?php
        $p_list = "1,2,3,4";

        $noArr = explode(",", $p_list);  

        var_dump($noArr);
?>

You will get array with values stores in it.
