How do I get specific values from a json encoded string?

[jonnyenglish89]

Hey guys,

 

I needed to covert the $main array in to a string so I used json_encode to do it but now I’m unsure how to get just the key values for $main[0] and $main[1] – can anyone help?


main array:

Array
(
    [0] => Array
        (
            [25256] => 1
        )

    [1] => Array
        (
            [50005] => 1
        )

    [2] => Array
        (
            [301] => 1
            [2318] => 1
            [13403] => 1
            [49489] => 1
        )

)

current code and output:

$com_id = json_encode($main[0]); = {"25256":1}
	
$dom_id = json_encode($main[1]); = {"50005":1}
	
$car_id = json_encode($main[2]); = {"301":1,"2318":1,"13403":1,"49489":1}

Desired output:

$com_id = {"25256"}
	
$dom_id = {"50005"}
	
$car_id = {"301":1,"2318":1,"13403":1,"49489":1}

ok, I'm still stuck... I've tried this:

foreach($main as $key => $value) {
	$t[] = array_keys($value);
	}
$com_id = json_encode($t[0]); = [25256]
    
$dom_id = json_encode($t[1]); = [50005]

when I do a var_dump it says it's a string:

string(7) "[25256]"

what am I doing wrong?

nevermind...

	$com_array =  array_keys($main[0]);
	$com_id = $commander_array[0];
	
	$dom_array =  array_keys($main[1]);
	$dom_id = $dominion_array[0];
	
	$cards = json_encode($main[2]);

this does the trick.
