PHP search values from multidimensional array-CodePudding

I have two arrays as following:

$price = [
    34 => 65.00,
    35 => 95.00,
    36 => 125.00,
];

$dbPrices = [
    36 => [
        'sales_price' => 125.00,
        'our_price' => 0.00
    ],
    35 => [
        'sales_price' => 98.00,
        'our_price' => 0.00
    ],
    34 => [
        'sales_price' => 70.00,
        'our_price' => 65.00
   ]
];

What I really want to find out if the values in the $price array are exist in the second array. It this case it can be check either sales_price or our_price contains the value from the $price array.

If those values in the $price array cannot be found in the second array, a new array must be created from those values.

So, new array should be as follow:

$newPrices = [35 => 95]

This is how I tried it. $dbPrices is my second array:

$discountItems = [];
$discountItems = array_intersect_key($price, $dbPrices);

$filter = function($v,$k) use($dbPrices){
return array_values($dbPrices[$k]) != $v;
};

$newPrices = array_filter($discountItems, $filter, ARRAY_FILTER_USE_BOTH );

It doesn't work in this way. Can anybody help me regarding this?

Your filter logic is currently comparing an array to a number. I believe the solution you're looking for may be as simple as utilizing in_array:

<?php

$price = [
    34 => 65.00,
    35 => 95.00,
    36 => 125.00,
];

$dbPrices = [
    36 => [
        'sales_price' => 125.00,
        'our_price' => 0.00
    ],
    35 => [
        'sales_price' => 98.00,
        'our_price' => 0.00
    ],
    34 => [
        'sales_price' => 70.00,
        'our_price' => 65.00
    ]
];


$discountItems = [];
$discountItems = array_intersect_key($price, $dbPrices);

$filter = function($v,$k) use($dbPrices){
    return !in_array($v, array_values($dbPrices[$k]));
};

$newPrices = array_filter($discountItems, $filter, ARRAY_FILTER_USE_BOTH );

print_r($newPrices);

The output:

Array ( [35] => 95 )

You can use foreach and compaire $price array with $dbPrices using it's key. if sales_price or our_price match then loop continue else store $price array value which not match in $dbPrices array. try below code.

 <?php
        $price = [
            34 => 65.00,
            35 => 95.00,
            36 => 125.00,
        ];
        
        $dbPrices = [
            '36' => [
                'sales_price' => 125.00,
                'our_price' => 0.00
            ],
            '35' => [
                'sales_price' => 98.00,
                'our_price' => 0.00
            ],
            '34' => [
                'sales_price' => 70.00,
                'our_price' => 65.00
           ]
        ];
        
        $newPrices = [];
        foreach($dbPrices as $key => $value ) {
            if ($price[$key] == $value['sales_price'] || $price[$key] == $value['our_price']) {
                continue;   
            }else{
                $newPrices[$key] = $price[$key];
            }
        }
    
    print_r($newPrices);
    ?>
