Sort Object in PHP

Sort array of objects by one property

Use usort, here's an example adapted from the manual:

function cmp($a, $b) {
    return strcmp($a->name, $b->name);
}

usort($your_data, "cmp");

You can also use any callable as the second argument. Here are some examples:

Using anonymous functions (from PHP 5.3)

  usort($your_data, function($a, $b) {return strcmp($a->name, $b->name);});

From inside a class

  usort($your_data, array($this, "cmp")); // "cmp" should be a method in the class

Using arrow functions (from PHP 7.4)

  usort($your_data, fn($a, $b) => strcmp($a->name, $b->name));

Also, if you're comparing numeric values, fn($a, $b) => $a->count - $b->count as the "compare" function should do the trick, or, if you want yet another way of doing the same thing, starting from PHP 7 you can use the Spaceship operator, like this: fn($a, $b) => $a->count <=> $b->count.

How to sort Object Array Collection by value in PHP

You can either use usort()

$test = array(array("col_header" => "other_1",
                    "col_order" => 12,
                    "data" => "asdgasdgfasdg"),
              array("col_header" => "other_2",
                    "col_order" => 10,
                    "data" => "dfhgsdhgsd"),
              array("col_header" => "other_3",
                    "col_order" => 11,
                    "data" => "s"));

usort($test, function($a, $b)
             {
                 if ($a["col_order"] == $b["col_order"])
                     return (0);
                 return (($a["col_order"] < $b["col_order"]) ? -1 : 1);
             });

var_dump($test);

Output :

array (size=3)
  0 => 
    array (size=3)
      'col_header' => string 'other_2' (length=7)
      'col_order' => int 10
      'data' => string 'dfhgsdhgsd' (length=10)
  1 => 
    array (size=3)
      'col_header' => string 'other_3' (length=7)
      'col_order' => int 11
      'data' => string 's' (length=1)
  2 => 
    array (size=3)
      'col_header' => string 'other_1' (length=7)
      'col_order' => int 12
      'data' => string 'asdgasdgfasdg' (length=13)

But I suggest you to sort your results directly from the SQL query :

SELECT *
FROM yourTable
...
ORDER BY col_order ASC

PHP sort array of objects by two properties

Why the extra level of indirection and making things more confusing? Why not usort directly with usort($objectArray, "sortObjects"); using a sortObjects($a,$b) function that does what any comparator does: return negative/0/positive numbers based on the input?

If the tabs differ, return their comparison, if they're the same, return the order comparison; done.

$array = array(
    (object)array(
        'tab_option_name_selector' => 2,
        'fieldtype' => 'notes',
        'order' => 12
    ),
    (object)array(
        'tab_option_name_selector' => 2,
        'fieldtype' => 'notes',
        'order' => 8
    ),
    (object)array(
        'tab_option_name_selector' => 1,
        'order' => 2,
        'fieldtype' => 'selectbox'
    ),
    (object)array(
        'tab_option_name_selector' => 2,
        'order' => 3,
        'fieldtype' => 'selectbox'
    )
);

function compareTabAndOrder($a, $b) {
    // compare the tab option value
    $diff = $a->tab_option_name_selector - $b->tab_option_name_selector;
    // and return it. Unless it's zero, then compare order, instead.
    return ($diff !== 0) ? $diff : $a->order - $b->order;
}

usort($array, "compareTabAndOrder");
print_r($array);

How can I sort object on laravel?

Don't reinvent the wheel. Laravel is a fantastic framework that did lots of work for you already.

First, you need to convert your array to a Collection:

$c = collect($c);

Now, For working with collections, you have a nice set of available methods you can work with. In your case, you need the sortBy():

$sorted = $c->sortBy('id');

Alternatively, you can pass a callback:

$sorted = $c->sortBy(function ($item, $key) {
    return $item->id;
});

Both of these will return a Collection object. If you want to get an Array back instead, use all() or toArray() on your result:

$c = $c->all();

// or

$c = $c->toArray();
