How to test whether PHP 5.6 was installed successfully

PHP is a popular server-side programming language used for building dynamic websites and applications. Although new versions have been released, PHP 5.6 is still used in many websites and applications. In this article, we will discuss how to test whether PHP 5.6 was successfully installed.

The test method for successful installation of PHP 5.6 is as follows:

1. Create a phpinfo.php file

Create a file named phpinfo.php file and copy the following code into the file:

<?php     phpinfo();
?>

This will generate a page containing PHP configuration information.

2. Open the phpinfo.php file in a web browser

Enter the URL of the web server in the web browser, followed by the name of the phpinfo.php file. For example: http://localhost/phpinfo.php. This will open the phpinfo.php file in your web browser.

3. Confirm PHP version

Search for "PHP Version" in the opened phpinfo.php file, and you can find the PHP version seconds in the box behind it. The version number of PHP 5.6.x should appear here.

4. Confirm required modules

Search for "Loaded Modules" in the opened phpinfo.php file. This module manifest should contain some required modules like mysql, mysqli, pdo_mysql, etc. If these modules are not in the module list, the PHP installation is incomplete. In this case, PHP needs to be rebuilt and ensure required modules are included correctly.

5. Test whether the PHP function is normal

Search for the "PHP Core" section in the opened phpinfo.php file and find the two lines "Zend Engine" and "Configuration". If both lines read "OK", it means that the basic functionality of PHP is normal. In addition, you can also test some PHP functions, such as echo and print. If everything goes well, these functions should output the expected results.

Summary:

You can confirm whether PHP 5.6 has been successfully installed by testing PHP configuration information, checking PHP version number, checking required modules, checking PHP core and testing PHP functions. These steps help build and maintain PHP websites and applications by ensuring that your PHP environment is functioning properly.
