After you install MySQL, you’re ready to install PHP. As I mention earlier, you must install MySQL before you install PHP because you may need to provide the path to the MySQL software when you install PHP. If PHP isn’t compiled with MySQL support when it is installed, it won’t communicate with MySQL.
Before you install PHP, check whether it’s already installed. For instance, some Linux and Mac distributions automatically install PHP. To see whether PHP is installed, search your disk for any PHP files:
Before you install PHP, check whether it’s already installed. For instance, some Linux and Mac distributions automatically install PHP. To see whether PHP is installed, search your disk for any PHP files:
- _ Linux/Unix/Mac: Type the following: find / -name “php*”
- _ Windows: Use the Find feature (choose StartFind) to search for php*.
If you find PHP files, PHP is already installed, and you might not need to reinstall it. For instance, even if you installed MySQL yourself after PHP was installed, you might have installed it in the location where PHP is expecting it. Better safe than sorry, however: Perform the testing that I describe in the next section to see whether MySQL and PHP are working correctly together.
If you don’t find any PHP files, PHP is not installed. To install PHP, you need access to the Web server for your site. For instance, when you install PHP with Apache, you need to edit the Apache configuration file. All the information and software that you need is provided on the PHP Web site (www.php.net).
