Are there any specific PHP functions or methods that can be used to replace commands in case of errors?

When encountering errors in PHP, it is important to handle them gracefully to prevent the script from crashing. One way to replace commands in case of errors is by using try-catch blocks. By wrapping the potentially problematic code in a try block and catching any exceptions in a catch block, you can execute alternative commands or display an error message instead. 

try {
    // Potentially problematic code here
    $result = 10 / 0; // Example of a division by zero error
} catch (Exception $e) {
    // Handle the error by executing alternative commands or displaying an error message
    echo "An error occurred: " . $e->getMessage();
}
