Array Diff Multidimensional

Works like the PHP array_diff() function, but with multidimensional arrays.

Install

Via composer:

composer require rogervila/array-diff-multidimensional

Usage

use Rogervila\ArrayDiffMultidimensional;
$new = [
    'a' => 'b',
    'c' => [
        'd' => 'e',
        'f' => 'Hello',
    ],
];
$old = [
    'a' => 'b',
    'c' => [
        'd' => 'e',
        'f' => 'Goodbye',
    ],
];
// Compare the arrays by calling the 'compare' class method
$result = ArrayDiffMultidimensional::compare($new, $old)
// Or by calling the global helper function
$result = array_diff_multidimensional($new, $old)
var_dump($result);

The result of comparing $new with $old will return a new array with the changes:

[
    'c' => [
        'f' => 'Hello'
     ],
]

Strict vs. Loose comparisons

Comparisons are strict by default, but you can specify that you want to make a loose comparison passing a boolean as the third parameter for compare method or calling the looseComparison

// Passing 'false' as a third parameter will deactivate the strict comparison mode
ArrayDiffMultidimensional::compare($new, $old, false);
array_diff_multidimensional($new, $old, false);
// This method call is equivalent
ArrayDiffMultidimensional::looseComparison($new, $old);

Also, a strictComparison method is available for more clarity

// Comparisons are strict by default
ArrayDiffMultidimensional::compare($new, $old);
array_diff_multidimensional($new, $old);
// This method call is equivalent
ArrayDiffMultidimensional::strictComparison($new, $old);
