What are some best practices for error handling in PHP when dealing with TCP connection issues?

When dealing with TCP connection issues in PHP, it's important to implement proper error handling to gracefully handle any potential errors that may arise. One best practice is to use try-catch blocks to catch exceptions thrown when establishing or using a TCP connection. Additionally, you can use PHP's error handling functions like error_reporting() and set_error_handler() to customize how errors are handled. 

<?php
try {
    // Attempt to establish a TCP connection
    $socket = @fsockopen('example.com', 80, $errno, $errstr, 5);
    
    if (!$socket) {
        throw new Exception("Failed to establish TCP connection: $errstr");
    }
    
    // Perform operations on the TCP connection
    
    // Close the TCP connection
    fclose($socket);
} catch (Exception $e) {
    // Handle the exception
    echo "Error: " . $e->getMessage();
}
?>
