一种方法:(为https://www.rfc-editor.org/rfc/rfc6902#section-4.6实现“考虑平等”)

这种方式允许关联数组的成员顺序不同——例如，除了php，它们在每种语言中都被认为是相等的:)

// recursive ksort
function rksort($a) {
  if (!is_array($a)) {
    return $a;
  }
  foreach (array_keys($a) as $key) {
    $a[$key] = ksort($a[$key]);
  }
  // SORT_STRING seems required, as otherwise
  // numeric indices (e.g. "0") aren't sorted.
  ksort($a, SORT_STRING);
  return $a;
}


// Per https://www.rfc-editor.org/rfc/rfc6902#section-4.6
function considered_equal($a1, $a2) {
  return json_encode(rksort($a1)) === json_encode(rksort($a2));
}

另一种不考虑值顺序检查是否相等的方法使用http://php.net/manual/en/function.array-intersect.php，如下所示:

$array1 = array(2,5,3);
$array2 = array(5,2,3);
if($array1 === array_intersect($array1, $array2) && $array2 === array_intersect($array2, $array1)) {
    echo 'Equal';
} else {
    echo 'Not equal';
}

下面是一个使用http://php.net/manual/en/function.array-uintersect.php:也可以用于多维数组的版本

$array1 = array(
    array(5, 2),
    array(3, 6),
    array(2, 9, 4)
);
$array2 = array(
    array(3, 6),
    array(2, 9, 4),
    array(5, 2)
);

if($array1 === array_uintersect($array1, $array2, 'compare') && $array2 === array_uintersect($array2, $array1, 'compare')) {
    echo 'Equal';
} else {
    echo 'Not equal';
}

function compare($v1, $v2) {
    if ($v1===$v2) {
        return 0;
    }
    if ($v1 > $v2) return 1;
    return -1;
}

array_diff -计算数组的差值

http://php.net/manual/en/function.array-diff.php

数组$array1，数组$array2[，数组$…]) 将array1与一个或多个其他数组进行比较，并返回array1中没有出现在任何其他数组中的值。

将它们与其他值进行比较:

if($array_a == $array_b) {
  //they are the same
}

你可以在这里阅读所有数组操作符: http://php.net/manual/en/language.operators.array.php 例如，请注意===还检查数组中元素的类型和顺序是否相同。

比较你的数组的值，也是多维的，关联的和任意组合的:

/**
 * @see PHPUnit Assert::assertEqualsCanonicalizing()
 * @return true if all keys and values are equal and of the same type,
 * irregardless of items or keys order
 */
function array_vals_equal(array $a, array $b): bool {
    // sort multi-dimensional recursive
    $_deep_sort = function (array $a) use (&$_deep_sort): array{
        // sort discarding index association or sort keys, depending on array type
        array_is_list($a) ? sort($a) : ksort($a);
        return array_map(fn($v) => is_array($v) ? $_deep_sort($v) : $v, $a);
    };
    // operator === checks that the count, types and order of the elements are the same
    return $_deep_sort($a) === $_deep_sort($b);
}

// Test cases
assertEquals(array_vals_equal([1], [1]), true, 'simple eq');
assertEquals(array_vals_equal([0], [false]), false, 'simple eq');
assertEquals(array_vals_equal([0], [null]), false, 'simple eq');
assertEquals(array_vals_equal([0, 1], [1, 0]), true, 'simple eq, diff order');
assertEquals(array_vals_equal([0, 1, 2], [1, 0]), false, 'diff count');
assertEquals(array_vals_equal([0, 1], [0, 1, 2]), false, 'diff count 2');
assertEquals(array_vals_equal([1, 2], [1, 2, 'hello']), false, 'diff count 3');
//
assertEquals(array_vals_equal([1, 2, 2], [2, 1, 1]), false, 'same vals repeated');
assertEquals(array_vals_equal([1, 2, 2], [2, 2, 1]), true, 'same vals, different order');
//
assertEquals(array_vals_equal([1, 2, 3], ['1', '2', '3']), false, 'int should not be eq string');
assertEquals(array_vals_equal([0 => 'a', 1 => 'b'], [0 => 'b', 1 => 'a']), true, 'same vals, diff order');
assertEquals(array_vals_equal(['a', 'b'], [3 => 'b', 5 => 'a']), true, 'same vals, diff indexes');
// associative arrays whose members are ordered differently
assertEquals(array_vals_equal(['aa' => 'a', 'bb' => 'b'], ['bb' => 'b', 'aa' => 'a']), true, 'dict with different order');
assertEquals(array_vals_equal(['aa' => 'a', 'bb' => 'b'], ['aa' => 'a']), false, 'a key is missing');
assertEquals(array_vals_equal(['aa' => 'a', 'bb' => 'b'], ['aa' => 'a', 'zz' => 'b']), false, 'dict same vals diff key');
// nested arrays with keys in different order
assertEquals(array_vals_equal(
    ['aa' => 'a', 'bb' => ['bb' => 'b', 'aa' => 'a']],
    ['aa' => 'a', 'bb' => ['aa' => 'a', 'bb' => 'b']]
), true, 'dict multi 2 level, keys in different order');
assertEquals(array_vals_equal(
    ['aa' => 'a', 'bb' => ['aa2' => 'a', 'bb2' => ['aa3' => 'a', 'bb3' => 'b']]],
    ['aa' => 'a', 'bb' => ['aa2' => 'a', 'bb2' => ['aa3' => 'a', 'bb3' => 'b']]]
), true, 'dict multi 3 level');
assertEquals(array_vals_equal(
    ['aa' => 'a', 'bb' => [0, 1]],
    ['aa' => 'a', 'bb' => [1, 0]]
), true, 'dict multi level, 2^ level sequential in different order');
assertEquals(array_vals_equal([[0, 1], ['a', 'b']], [['b', 'a'], [1, 0]]), true, 'multi level sequential');

如果你想生成一份详细的报告，你可以使用这样的东西:

function deepCompare(Array $a, Array $b, string $parentAKey, string $parentBKey, bool $compareInverted = true, bool $compareValues = true, string $log = '')
{
    foreach ($a as $aKey => $aValue) {
        $fullAKey = implode('.', [$parentAKey, $aKey]);
        $fullBKey = implode('.', [$parentBKey, $aKey]);
        if (! isset($b[$aKey])) {
            $log .= "⍰ {$fullAKey} has no equivalent {$fullBKey}\n";
        } else {
            $bValue = $b[$aKey];
            if (is_array($aValue)) {
                $log = deepCompare($aValue, $bValue, $fullAKey, $fullBKey, false, $compareValues, $log);
            } else {
              if ($compareValues) {
                  if ($aValue != $bValue) {
                      $log .= "≠ {$fullAKey} value differs from {$fullBKey}\n";
                  }
              }
            }
        }
    }
    if ($compareInverted) {
        $log = deepCompare($b, $a, $parentBKey, $parentAKey, false, false, $log);
    }
    return $log;
}

下面是一个例子:

$november = [
  'site1' => [
    'id' => 15,
    'name' => 'Brazil',
    'extendedHours' => 454,
  ],
  'site2' => [
    'id' => 43,
    'name' => 'Portugal',
    'extendedHours' => 448,
  ],
  'site3' => [
    'id' => 49,
    'name' => 'Spain',
    'extendedHours' => 0,
  ],  
  'totalExtendedHours' => 902,
];

$december = [
  'site1' => [
    'id' => 15,
    'name' => 'Brazil',
    'extendedHours' => 498,
  ],
  'site2' => [
    'id' => 43,
    'name' => 'Portugal',
    'extendedHours' => 409,
    'extraRequests' => 6,
  ],
  'totalExtendedHours' => 907,
  'totalExtraRequests' => 6,
];

echo deepCompare(
    $november,    -- origin array
    $december,    -- target array
    'Nov2022',    -- descriptive name of origin array
    'Dec2022',    -- descriptive name of target array
    true,         -- should also compare arrays in reverse order?
    true          -- should care about array values? (false = names only)
);

这个例子将输出:

≠ Nov2022.site1.extendedHours value differs from Dec2022.site1.extendedHours
≠ Nov2022.site2.extendedHours value differs from Dec2022.site2.extendedHours
⍰ Nov2022.site3 has no equivalent Dec2022.site3
≠ Nov2022.totalExtendedHours value differs from Dec2022.totalExtendedHours
⍰ Dec2022.site2.extraRequests has no equivalent Nov2022.site2.extraRequests
⍰ Dec2022.totalExtraRequests has no equivalent Nov2022.totalExtraRequests

我希望这能帮助到一些人。
