How to get max value in foreach php?

I'm fairly new to php and i have problem with loops. I have a foreach loop,

foreach [$contents as $g => $f]
{
  p[$f];
}

which gives some arrays, depending on how many contents i have. currently i have 2,

Array
[
    [quantity] => 1
    [discount] => 1
    [discount_id] => 0
    [id] => 1506
    [cat_id] => 160
    [price] => 89
    [title] => კაბა
]

Array
[
    [quantity] => 1
    [discount] => 1
    [discount_id] => 0
    [id] => 1561
    [cat_id] => 160
    [price] => 79
    [title] => ზედა
]

my goal is to save the array which has the max price in it as a different variable. I'm kinda stuck on how to do that, i managed to find the max price with the max[] function like so

foreach [$contents as $g => $f]
{

    $priceprod[] = $f['price'];
    $maxprice = max[$priceprod];
   p[$maxprice];
}

but i still dont get how i'm supposed to find out in which array is the max price. any suggestions would be appreciated

You should store the keys as well so that you can look it up after the loop:

$priceprod = array[];

foreach [$contents as $g => $f]
{
  // use the key $g in the $priceprod array
  $priceprod[$g] = $f['price'];
}

// get the highest price
$maxprice = max[$priceprod];

// find the key of the product with the highest price
$product_key = array_search[$maxprice, $priceprod];

$product_with_highest_price = $contents[$product_key];

Note that the results will be unreliable if there are multiple products with the same price.

Check max function for the array in outside the loop.

foreach [$contents as $g => $f]
{

    $priceprod[] = $f['price'];

}
$maxprice = max[$priceprod];
p[$maxprice];

Here you got single loop solution handling multiple items with same max price.

$maxPrice = - INF;
$keys = [];
foreach[$contents as $k=>$v]{
    if[$v['price']>$maxPrice]{
        $maxPrice = $v['price'];
        $keys = [$k];
    }else if[$v['price']==$maxPrice]{
        $keys[] = $k;
    }
}

Now a new problem.

I get the values from the code posted above but I just get the word Array when I try to use it with max[]

$arr = array[];
foreach[$array as $key => $add]{
$image_height = round[$_SESSION['imgheight'.$key]];
if[$add == "Yes"]
{
  $arr[] = $image_height;
}
}

rsort[$arr];

print_r[$arr];

That gives me

Array [ [0] => 379 [1] => 8 ]

for the print_r[$arr];

But when I try to use the MAX[] function with it

I use  max[array[$arr]];

And it just prints Array instead of the highest value??

I then tried putting it into a string

$works = implode[',', $arr];

echo $works;
$hgt = max[$works];

echo works gives me a comma sep. string of the values

But, I get Wrong parameter count for max when I use the variable.

Is there a different way to get the highest value?
