How can the DocumentRoot and DirectoryIndex settings in the httpd.conf file affect the execution of PHP scripts on an Apache server?

The DocumentRoot setting in the httpd.conf file determines the root directory from which the server serves files. If the DocumentRoot is not set correctly, Apache may not be able to locate the PHP scripts to execute them. The DirectoryIndex setting specifies the default file to serve when a directory is requested. If the DirectoryIndex is not set to include PHP files (e.g., index.php), Apache may not execute PHP scripts properly. To ensure that PHP scripts can be executed correctly on an Apache server, make sure that the DocumentRoot is set to the correct directory where the PHP scripts are located. Additionally, include PHP files in the DirectoryIndex setting to ensure that Apache knows to execute them by default. 

<IfModule dir_module>
    DirectoryIndex index.php index.html
</IfModule>
