What is the purpose of using "@" before fsockopen() in PHP and how does it affect error handling?

When using "@" before a function in PHP, it suppresses any errors or warnings that would normally be displayed. This can be useful when you want to handle errors yourself or prevent error messages from being shown to users. However, it is generally considered a bad practice as it can make debugging more difficult.

// Suppressing errors with "@" before fsockopen()
@$fp = fsockopen($hostname, $port, $errno, $errstr, $timeout);

// Check for errors manually
if(!$fp){
    echo "Error: $errstr ($errno)";
} else {
    // Continue with fsockopen logic
}
