∟Dump PHP/Apache Environment Information

This section provides a tutorial example on how to dump Apache/PHP environment information on CentOS Linux systems.

The execution environment of running PHP scripts on the Apache Web server is different than running them from the command line. You need to dump the Apache/PHP environment information as shown in this tutorial.

1. Publish the following script file, test_phpinfo.php, to the Apache Web server directory, /var/www/html/test:

<?php phpinfo(); ?>

2. View the script file as a Web page, http://localhost/test/test_phpinfo.php in a Web browser. You should see the Apache/PHP environment information displayed in a nice format.

Now I know where to go find the Apache/PHP error log file:

centos$ sudo ls -l /var/log/php-fpm/
