PHP Foreach query checking

Question

Array
(
    [0] => Array
        (
            [cart_id] => 24763
            [product_id] => 740
            [name] => Samsung S20
            [model] => Samsung S20
            [shipping] => 1
            [image] => catalog/samsung/samsungs20.jpg
            [option] => Array
                (
                )

            [download] => Array
                (
                )
        )

    [1] => Array
        (
            [cart_id] => 24799
            [product_id] => 749
            [name] => Huawei P40
            [model] => Huawei P40
            [shipping] => 1
            [image] => catalog/huawei/huaweip40.jpg
            [option] => Array
                (
                )

            [download] => Array
                (
                )
        )

)

^ Above is the output of the array

$productdata = $this->cart->getProducts();

^ Above is the code for query out array

is there anyway to check product_id of each array ? Let say that if product_id = 749 , alert ('P40');

Tried to do

foreach ($productdata as $productdatas) {
    if ($productdata['product_id'] = 749)
    { alert('P40'); 
    }

}

nothing happen

The code you say you tried has syntax errors so it won't run at all. Please read this to see how to make a minimal, reproducible example so we can see the problem and be able to help. — FluffyKitten

Take a look at the variables you use in foreach and then look at which of these variables you use to check the product id... do you see the problem now? — FluffyKitten

This part sets the key, not read it. You need to replace the = with ==:

// From
if ($productdata['product_id'] = 749)

// To
if ($productdata['product_id'] == 749)
