What is the significance of the pipe symbol in the test string '/msg USER TEXT' mentioned in the discussion?

The pipe symbol "|" in the test string '/msg USER TEXT' is used as a delimiter to separate different parts of the string. In this case, it is separating the command "msg", the recipient "USER", and the message "TEXT". To parse this string and extract the individual components, we can use the `explode()` function in PHP, specifying the pipe symbol as the delimiter. 

// Test string
$string = '/msg|USER|TEXT';

// Explode the string using the pipe symbol as the delimiter
$parts = explode('|', $string);

// Extract the individual components
$command = $parts[0]; // 'msg'
$recipient = $parts[1]; // 'USER'
$message = $parts[2]; // 'TEXT'

// Output the components
echo "Command: $command\nRecipient: $recipient\nMessage: $message";
