How does the Apache server determine which file types are sent to the parser in PHP?

The Apache server determines which file types are sent to the PHP parser based on the configuration settings in the Apache configuration file (httpd.conf). The AddType directive is used to specify which file extensions should be processed by the PHP interpreter. By adding the appropriate AddType directive for PHP files, Apache will send those files to the PHP parser for execution. ```apache # AddType directive to send .php files to PHP parser AddType application/x-httpd-php .php ```
