Info & Debugging

List Plugins - This will list all of the available plugin in the WordPress plugin directory. Useful to check the installed plugins in your installation.

<?php

// Directory to scan
$files = scandir("wp-content/plugins");

// Return the result of the scan
foreach($files as $file) {
    echo $file."\n";
}

Test Database Connection - This will return a database connection status. This is useful to when you want to make sure your database credentials are working correctly or not.

<?php

// Test Database Connection
$servername = "localhost";
$username = "username-here";
$password = "password-here";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";

View File Contents - Able to view file contents in your installation. For example, you want to check the wp-config.php contents.

<?php

// define specific file
$file = "./wp-config.php";

// do the magic
$view = file_get_contents($file, true);

// return the results
echo $view;

Check Free Disk Space - This will return the total free disk space on your web server.

<?php

// checking disk space
$bytes = disk_free_space(".");

// setting up arraw for prefix
$si_prefix = array( 'B', 'KB', 'MB', 'GB', 'TB', 'EB', 'ZB', 'YB' );

// do the magic with math!
$base = 1024;
$class = min((int)log($bytes , $base) , count($si_prefix) - 1);

// return the result
echo "Remaining disk space is " . sprintf('%1.2f' , $bytes / pow($base,$class)) . ' ' . $si_prefix[$class];
