Many times we need to find the max/min value of a particular key from an multidimensional array Below are the function through which we can get these values. Please check example right below it.
Example
$arr= array(array(110, 20, 52),array(105, 56, 89, 96),array( 556, 89, 96));
$b = 0;
foreach ($arr as $val)
{
foreach($val as $key=>$val1)
{
if ($val1 > $b)
{
$b = $val1;
}
}
}
echo $b;
?>
