Question

So here is my array:

array(1) { [0]=> string(79) “{“form_array”:{“element1″:”value1″,”element2″:”value2″,”element3″:”value3″}}” }

How can I extract “form_array” as an array?

Answer 1

You actually have just a simple array with one element, which is a string, that seems to be JSON encoded. To get its data, you may use the following:

// get the string
$data = $array[0];

// decode the content
$data = json_decode( $data, true );

// get the sub array
$data = $data['form_array'];

_{The steps may of course be simplified into a single row. I just separated them for readability and clarity.}
