# PHP Math Exercises: Find the maximum and minimum marks from the specified set of arrays

## PHP math: Exercise-1 with Solution

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);

Visual Presentation:

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".
