How to go through 2 distinct arrays to verify which values are equal and after the check print only the equal values of both arrays?

The arrays' structures are in the following form below, I tried to traverse using Function in_array but it doesn’t work, someone can help?

Array 1

Array
(
    [0] => Array
        (
            [id] => 1899
            [bola1] => 1
            [bola2] => 3
            [bola3] => 5
            [bola4] => 6
            [bola5] => 9
            [bola6] => 10
            [bola7] => 11
            [bola8] => 14
            [bola9] => 15
            [bola10] => 16
            [bola11] => 17
            [bola12] => 18
            [bola13] => 19
            [bola14] => 20
            [bola15] => 23
        )

)

Array 2

Array
(
    [0] => Array
        (
            [id] => 1
            [bola1] => 1
            [bola2] => 2
            [bola3] => 3
            [bola4] => 4
            [bola5] => 6
            [bola6] => 7
            [bola7] => 8
            [bola8] => 10
            [bola9] => 11
            [bola10] => 13
            [bola11] => 14
            [bola12] => 18
            [bola13] => 20
            [bola14] => 21
            [bola15] => 24
        )

)
php array loop

  • Does the key and value have to be equal? Only the value? Only the key?

  • Only the value, for example: the key value [ball1] of Array 1 is 1, the key value [ball1] of Array 2 is 1 so they are equal, prints 1. Already the key value [ball2] of Array 1 is 3, the key value [ball2] of Array 2 is 2, so they are not equal, captured the idea?

  • See if the array_intersect serves https://www.php.net/manual/en/function.array-intersect.php.

  • It didn’t work with this array_intersect function

In your case the array is inside another array, try this.

$result = array_intersect($array1[0], $array2[0]);

print_r($result);

You’ve tried it this way ?

$arrNumber = [1,2,3,4,5]; $otherArr = [1,3,7,9];

foreach($arrNumber as $arr){ foreach ($otherArr as $v) { if($arr === $v){ print 'Equal values:'. $v ."
"; } } }

if it is an array within another array it traverses the first level and then the second one comparing the values.
