PHP Exercises : Compare the PHP version

PHP : Exercise-23 with Solution

Write a PHP script to compare the PHP version.

Note : Use version_compare() function and PHP_VERSION constant.

Sample Solution:

PHP Code:

<?php
// Check if PHP version is at least 6.0.0
if (version_compare(PHP_VERSION, '6.0.0') >= 0) {
    echo 'I am at least PHP version 6.0.0, my version: ' . PHP_VERSION . "\n";
}

// Check if PHP version is at least 5.3.0
if (version_compare(PHP_VERSION, '5.3.0') >= 0) {
    echo 'I am at least PHP version 5.3.0, my version: ' . PHP_VERSION . "\n";
}

// Check if PHP version is at least 5.0.0
if (version_compare(PHP_VERSION, '5.0.0', '>=')) {
    echo 'I am using PHP 5, my version: ' . PHP_VERSION . "\n";
}

// Check if PHP version is less than 5.0.0
if (version_compare(PHP_VERSION, '5.0.0', '<')) {
    echo 'I am using PHP 4, my version: ' . PHP_VERSION . "\n";
}
?>

Sample Output:

I am at least PHP version 6.0.0, my version: 7.0.15-0ubuntu0.16.04.4
I am at least PHP version 5.3.0, my version: 7.0.15-0ubuntu0.16.04.4
