Trouble while installing PHP in Manjaro (LAMP)

I have some trouble while I’m installing PHP to Manjaro Linux through the terminal. I used the below tutorial to install MySQL and PHP.

I have done the 1. Update your system, 2. Install Apache, 3. Install MariaDB parts, and there is no issue. Also, the Apache server and MariaDB ran perfectly without any issue. But while part 4 (install PHP), when I uncomment the “LoadModule mpm_prefork_module modules/mod_mpm_prefork.so” in httpd.conf file, I can’t run the Apache server. The screenshots are attached below. I hope someone can solve this.
