PHP Exercises : Print current PHP version

PHP : Exercise-17 with Solution

Write a PHP script to print current PHP version.

Note : Do not use phpinfo() function.

Sample Solution:

PHP Code:

<?php
// Output the current PHP version
echo 'Current PHP version : ' . phpversion();

// Output the version of the Tidy extension, or nothing if the extension isn't enabled
echo phpversion('tidy')."\n";
?>

Explanation:

• Display PHP Version:
• phpversion() without arguments returns the current PHP version as a string.
• echo displays this version with the message "Current PHP version : ".
• Check Tidy Extension Version:
• phpversion('tidy') checks the version of the Tidy extension if it’s enabled.
• If the Tidy extension is installed, it outputs the version. If not, it returns an empty string.

Output:

Current PHP version : 7.0.15-0ubuntu0.16.04.4 

Flowchart:

Note: string phpversion (string $extension ): Returns a string containing the version of the currently running PHP parser or extension.
