Are there any best practices for using the system() function in PHP to avoid unnecessary output?

When using the system() function in PHP to execute shell commands, it can sometimes produce unwanted output that gets displayed on the screen. To avoid this, you can redirect the output to /dev/null or use the output buffering functions to capture and suppress the output. 

// Redirecting output to /dev/null
system('your_command > /dev/null 2>&1');

// Using output buffering to capture and suppress output
ob_start();
system('your_command');
ob_end_clean();
