What potential issues can arise when trying to identify multiple servers by PID in PHP?

When trying to identify multiple servers by PID in PHP, potential issues can arise if multiple servers are running on the same machine and have the same PID. To solve this issue, you can generate unique PIDs for each server by combining the server's hostname with a unique identifier. 

// Generate a unique PID for the server by combining the hostname with a unique identifier
$pid = gethostname() . '_' . uniqid();

// Use the unique PID to identify the server
echo "Server PID: " . $pid;
