Warning: array_values() expects parameter 1 to be array

Question

I insert data array into database like this :

$value['gallery_data'] = array();
$value['gallery_data'] = serialize((array(array_values("name"), array_values("url"), array_values("type")))); // LINE 843

In database:

a:3:{i:0;N;i:1;N;i:2;N;}

I see this error in action:

Warning: array_values() expects parameter 1 to be array, string given in C:\xampp\htdocs\user\modules\editnews.php on line 843

Warning: array_values() expects parameter 1 to be array, string given in C:\xampp\htdocs\user\modules\editnews.php on line 843

Warning: array_values() expects parameter 1 to be array, string given in C:\xampp\htdocs\user\modules\editnews.php on line 843

EDIT:

I need to insert this format for multiple array in database:

a:3:{i:0;a:4:{i:0;s:48:"uploads/media/galleries/nature/butterfly_001.jpg";i:1;s:43:"uploads/media/galleries/nature/IMG_4181.jpg";i:2;s:43:"uploads/media/galleries/nature/swan_002.jpg";i:3;s:45:"uploads/media/galleries/nature/zzmed copy.jpg";}i:1;a:4:{i:0;s:19:"test_title";i:1;s:20:"test_title1";i:2;s:25:"test_title2";i:3;s:24:"677777777777777777777777";}i:2;a:4:{i:0;s:19:"test_alt";i:1;s:21:"test_alt1";i:2;s:21:"test_alt2";i:3;s:26:"77888888888888888888888888";}}

how do can i fix this ?

Warning clearly says array_values() expects parameter 1 to be array — Sadikhasan

you need to do unserialize before passing this array in array_values() function. — Code Lღver

Please read the documentation for the array_values() function - you are using it incorrectly. — Ken Herbert

I feel you are using array_values before array so try something like this

$value['gallery_data'] = serialize(array_values(array("key1" => "name", "key2" => "url", "key3" => "type")));

or like this

$value['gallery_data'] = serialize(array("name" , "url", "type")); // LINE 843

I didn't get your point? If you want to insert it in db than you can insert it in db and un-serialize it after your retrieve it. if you are looking for something different than describe it clearly

No need of array_value() here

No need of array_value() here

Reason

print_r(array("name", "url", "type"));
//output
Array ( [0] => name [1] => url [2] => type )
//output
print_r(array_values(array("name", "url", "type")));
Array ( [0] => name [1] => url [2] => type )

Try:

$value['gallery_data'] = serialize(array("name", "url", "type")); // LINE 843

WORKING DEMO

Passing multiple array in single array like this:

Try:

$value['gallery_data'] = array();
echo $value['gallery_data'] = serialize(array(
    array(
        "uploads/media/galleries/nature/butterfly_001.jpg", 
        "uploads/media/galleries/nature/IMG_4181.jpg", 
        "uploads/media/galleries/nature/swan_002.jpg",
        "uploads/media/galleries/nature/zzmed copy.jpg",
    ),
    array("test_title", 
          "test_title1", 
          "test_title2",
          "test_title3"
         ),
    array("test_alt",
          "test_alt1",
          "test_alt2",
          "test_alt3"
    )
)); // LINE 843

Output as you want:

a:3:{i:0;a:4:{i:0;s:48:"uploads/media/galleries/nature/butterfly_001.jpg";i:1;s:43:"uploads/media/galleries/nature/IMG_4181.jpg";i:2;s:43:"uploads/media/galleries/nature/swan_002.jpg";i:3;s:45:"uploads/media/galleries/nature/zzmed copy.jpg";}i:1;a:4:{i:0;s:10:"test_title";i:1;s:11:"test_title1";i:2;s:11:"test_title2";i:3;s:11:"test_title3";}i:2;a:4:{i:0;s:8:"test_alt";i:1;s:9:"test_alt1";i:2;s:9:"test_alt2";i:3;s:9:"test_alt3";}}

You're passing a string to the array_values function instead of an array.

So replace array_values("name") with array_values($someArray) for example.
