PHP Math Exercises: Find the maximum and minimum marks from the specified set of arrays
Write a PHP script to find the maximum and minimum marks from the following set of arrays.
Sample arrays :
$marks1 = array(360,310,310,330,313,375,456,111,256);
$marks2 = array(350,340,356,330,321);
$marks3 = array(630,340,570,635,434,255,298);

Sample Solution:
PHP Code:
<?php
// Define arrays of marks for three subjects
$marks1 = array(360,310,310,330,313,375,456,111,256);
$marks2 = array(350,340,356,330,321);
$marks3 = array(630,340,570,635,434,255,298);
// Find the maximum marks among all subjects
$max_marks = max(max($marks1), max($marks2), max($marks3));
// Find the minimum marks among all subjects
$min_marks = min(min($marks1), min($marks2), min($marks3));
// Output the maximum and minimum marks
echo "Maximum marks : ".$max_marks."\n";
echo "Minimum marks : ".$min_marks."\n";
?>
Output:
Maximum marks : 635 Minimum marks : 111
Explanation:
The above PHP code finds the maximum and minimum marks among three arrays of marks for different subjects.
- Three arrays named '$marks1', '$marks2', and '$marks3' contain marks for different subjects.
- The "max()" and "min()" functions are used to find the maximum and minimum values in each array.
- "max()" and "min()" functions are again used with all three arrays as arguments to find the overall maximum and minimum marks across all subjects.
- The maximum and minimum marks are then printed out using "echo".
