php - foreach max array value? -

i'm new php , have problem loops. have foreach loop,

foreach ($contents $g => $f) {   p($f); } 

which gives arrays, depending on how many contents have. 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 save array has max price in different variable. i'm kinda stuck on how that, managed find max price max() function so

foreach ($contents $g => $f) {      $priceprod[] = $f['price'];     $maxprice = max($priceprod);    p($maxprice); } 

but still dont how i'm supposed find out in array max price. suggestions appreciated

you should store keys can after loop:

$priceprod = array();  foreach ($contents $g => $f) {   // use key $g in $priceprod array   $priceprod[$g] = $f['price']; }  // highest price $maxprice = max($priceprod);  // find key of product highest price $product_key = array_search($maxprice, $priceprod);  $product_with_highest_price = $contents[$product_key]; 

note results unreliable if there multiple products same price.
