PHP program to find the maximum element in an array

To find the maximum element in an array, the PHP code is as follows −

Example

 Live Demo

<?php
   function get_max_value($my_array){
      $n = count($my_array);
      $max_val = $my_array[0];
      for ($i = 1; $i < $n; $i++)
         if ($max_val < $my_array[$i])
            $max_val = $my_array[$i];
      return $max_val;
   }
   $my_array = array(56, 78, 91, 44, 0, 11);
   print_r("The highest value of the array is ");
   echo(get_max_value($my_array));
   echo("
");
?>

Output

The highest value of the array is91

A function named ‘get_max_value()’ is defined, that takes an array as parameter. Inside this function, the count function is used to find the number of elements in the array, and it is assigned to a variable −

$n = count($my_array);

The first element in the array is assigned to a variable, and the array is iterated over, and adjacent values in the array are compared, and the highest value amongst all of them is given as output −

$max_val = $my_array[0];
for ($i = 1; $i < $n; $i++)
   if ($max_val < $my_array[$i])
      $max_val = $my_array[$i];
return $max_val;

Outside the function, the array is defined, and the function is called by passing this array as a parameter. The output is displayed on the screen −

$my_array = array(56, 78, 91, 44, 0, 11);
print_r("The highest value of the array is");
echo(get_max_value($my_array));
