47. Increasing Order Check for x,y,z

Write a PHP program to check if y is greater than x, and z is greater than y from three given integers x,y,z.

Sample Solution:

PHP Code :

<?php
// Define a function that checks if $x is less than $y and $y is less than $z
function test($x, $y, $z)
{
    // Check if $x is less than $y AND $y is less than $z
    return $x < $y && $y < $z;
}

// Test the function with different sets of numbers
var_dump(test(1, 2, 3))."\n";
var_dump(test(4, 5, 6))."\n";
var_dump(test(-1, 1, 0))."\n";
?>

Explanation:

Function Definition:

The function test checks if the numbers follow a strictly increasing order, i.e., $x < $y and $y < $z.

Condition Checked:

Condition: It returns true if $x is less than $y and $y is less than $z; otherwise, it returns false.

Output:

bool(true)
bool(true)
bool(false)
