This is my array format:
$data=["error.png","invoice_1.pdf","invoice2.png"];
But I want to this format:
$data=[{"file":"error.png"},{"file":"invoice_1.pdf"},{"file":"invoice2.png"}]
Thank you.

why would you want to give the same key to all variables ?Att3t– Att3t2014-11-21 10:24:50 +00:00Commented Nov 21, 2014 at 10:24

1This really is very simple logic. You've made no attempt to do this yourself & evidently not even searched for what you wanted, because you're most definitely not this first to want to do this simple thing.user4273579– user42735792014-11-21 11:14:52 +00:00Commented Nov 21, 2014 at 11:14

You should create a new array.
And loop through your existing array.
Its every element will be an array with a value from your array as value.
And key as the string file.
$arr = array();
foreach ($data as $elem) {
$arr[] = array('file' => $elem);
}
Try debugging if you get the correct array:
echo '<pre>';
print_r($arr);
echo '</pre>';
Lastly,
echo json_encode($arr);
exit;
Hope it works for you.

Use
$data = array_map(
function ($item) {
return array('file' => $item);
},
$data
);
to embed the values into arrays, or
$data = array_map(
function ($item) {
$x = new stdClass();
$x->file = $item;
return $x;
},
$data
);
to embed them into objects.
Or, better, use your own class instead of stdClass() and pass $item as argument to its constructor
$data = array_map(
function ($item) {
return new MyClass($item);
},
$data
);

$data = ["error.png", "invoice_1.pdf", "invoice2.png"];
$newarray = array();
foreach ($data as $val){
array_push($newarray, array("file" => $val));
}
print_r($newarray); //Array ( [0] => Array ( [file] => error.png ) [1] => Array ( [file] => invoice_1.pdf ) [2] => Array ( [file] => invoice2.png ) )
echo json_encode($newarray); // [{"file":"error.png"},{"file":"invoice_1.pdf"},{"file":"invoice2.png"}]
exit;
Just try this logic

$data = '["error.png","invoice_1.pdf","invoice2.png"]';
$data = json_decode($data);
$data = array_filter($data, function(&$item){return ($item = array('file' => $item));});
$data = json_encode($data);
