How to convert array index key from [] to ""

Question

I am stuck somewhere in arrays. I am getting an array like:

Array
(
    [0] => name
    [1] => description
)

And I want to convert that into :

Array
(
    "0" => name
    "1" => description
)

I have found on google enough for this but did not found any solution, and don't think it is object array.

Can someone please help me out in this.

Thanks

I am still not getting any solution for this on that link. Can you please help me out? — Geek, Apr 23 '16 at 15:13

Based on the duplicated answer, this is how you should do it

$data = array(0 =>'name', 1=> 'description');

$keys = array_keys($data);
$values = array_values($data);

$stringKeys = array_map('strval', $keys);
$data = array_combine($stringKeys, $values);
var_dump($data);

Output

array(2) { 
    [0]=> string(4) "name" 
    [1]=> string(11) "description" 
}

There is a small syntax error there- array_map($keys, 'strval') should be array_map('strval', $keys)

BTW, I don't understand why you need this:

$data = array("name", "description");

echo $data[0]; // output: "name"
echo $data["0"]; // Also output: "name"

So in both cases you get the same output

@LightnessRacesinOrbit Maybe i didn't understood the question correctly. Doesn't the OP requested to convert the array keys to strings? – Alon Eitan Apr 23 '16 at 15:33
I want to convert [0] to "0" because, I have 2 arrays and I further want there difference by array_diff. and array_diff does not accept array index as [0] – Geek Apr 23 '16 at 15:38
@addy I suggest you should update the question white this important information, and explain why do you think it's not a duplicate. You should also **include the code that doesn't work** because people like to see what have you tried before asking the question (You can combine it with the code from my answer) - This will reopen your question and allow us to help you. – Alon Eitan Apr 23 '16 at 15:52

You're misreading the output. The keys are not [0] and [1]; they are the integers 0 and 1, stylised for debug output.

You can have string keys instead if you like (i.e. ["0"] and ["1"] in the output), but since PHP will coerce between the two as needed anyway, there's really no point.
