PHP Convert string into array

问题

How to convert a string $string = 'array(array("a"=>"content"))'; (<-- this is string) into array like this:

array(1) { [0]=> array(1) { ["a"]=> string(7) "content" } }

I am going to build a function to run serialize online:

Input: $string = 'array(array(1))'; echo serialize($string);

Result: a:1:{i:0;a:1:{i:0;i:1;}} NOT s:16:"array(array(1)))";

You call: $returnValue = serialize('array(array(1))');

回答1:

You /could/ use eval():

$string = 'array(array("a"=>"content"))';
eval("\$array = $string;");
print_r($array);

Output:

Array
(
    [0] => Array
        (
            [a] => content
        )

)

But if you're accepting user inputs, you should not use eval().

Also, consider using json_encode() / json_decode() instead.

Alternatively, to store arrays in strings, you could use serialize and unserialize.

eval? check http://php.net/manual/en/function.eval.php

take note on the Caution the manual shows...
