Here I want to remove last array from below (this is always last array that is set dynamically):

array(1) {
  ["file-1573204001988"]=>
  array(3) {
    [0]=>
    array(5) {
      ["name"]=>
      string(7) "abc.png"
      ["type"]=>
      string(9) "image/png"
      ["tmp_name"]=>
      string(14) "/tmp/phpdl81UY"
      ["error"]=>
      int(0)
      ["size"]=>
      int(72761)
    }
    [1]=>
    array(5) {
      ["name"]=>
      string(12) "profiles.png"
      ["type"]=>
      string(9) "image/png"
      ["tmp_name"]=>
      string(14) "/tmp/phptIFS1J"
      ["error"]=>
      int(0)
      ["size"]=>
      int(16178)
    }
    [2]=>
    array(5) {
      ["name"]=>
      string(0) ""
      ["type"]=>
      string(0) ""
      ["tmp_name"]=>
      string(0) ""
      ["error"]=>
      int(4)
      ["size"]=>
      int(0)
    }
  }
}

I want to remove whole below array from above (when it have empty name):

[2]=>
    array(5) {
      ["name"]=>
      string(0) ""
      ["type"]=>
      string(0) ""
      ["tmp_name"]=>
      string(0) ""
      ["error"]=>
      int(4)
      ["size"]=>
      int(0)
    }

How this can possible I tried with array_pop, unset and other predefined php functions but not getting the correct result. Please help me out to reach the correct value Thanks in advance

If you are persistently trying to remove the last element within the array, you can use array_pop.

array_pop() pops and returns the value of the last element of array, shortening the array by one element.

$myArray = array(
    0 => "hello",
    1 => "world",
    2 => "remove me",
);

array_pop($myArray); // Removes [2] from the array above.

In your case, you would simply do:

array_pop($array["file-1573204001988"]);

A simple foreach loop with a simple test in it will do this for you

foreach ($arr['file-1573204001988'] as $key=>$a){
    if ( $a['name'] = '' ){
        unset($arr['file-1573204001988'][$key]);
    }
}
user_23108300

These look like items of $_FILES array. Instead of checking the name I would recommend checking the value of error and filter out anything that's not UPLOAD_ERR_OK or 0

$valid_files = array_filter($arr["file-1573204001988"],
     fn($item) => $item['error'] === UPLOAD_ERR_OK);
