php call array from string

Question

I have a string that contains elements from array.

$str = \'[some][string]\';
$array = array();

How can I get the value of $array[\'some\

Answer 1

This will work for any number of keys:

$keys = explode('][', substr($str, 1, -1));
$value = $array;
foreach($keys as $key)
    $value = $value[$key];

echo $value
