PHP将带有方括号的逗号分隔字符串转换为数组

Question

My string looks like:

[10,20,30]

I want to convert it to an array.

I've tried:

$myArray=explode(",",$myString);
print_r($myArray);

But this is returning:

Array ( [0] => [10 [1] => 20 [2] => 30] )

I need to get rid of the opening/closing brackets.

Can someone help?

An array of numbers in that particular format is valid JSON, so you can use PHP’s built-in function:

$myArray = json_decode($myString);
