How to use try-catch block In PHP
When an exception is thrown, the normal execution flow is interrupted, and PHP will search for the nearest catch
block that can handle the exception. If no suitable catch
block is found, PHP will terminate the script and display an uncaught exception error message.
try {
// Code that may throw an exception
throw new Exception("An error occurred");
} catch (Exception $e) {
// Handling the exception
echo "Exception caught: " . $e->getMessage();
}
In this example, the catch
block catches the exception thrown within the try
block and handles it by printing out the error message. You can include additional logic within the catch
block to handle exceptions as needed, such as logging errors or displaying user-friendly error messages.
How to throw an Exception in PHP?
In PHP, you can throw exceptions to indicate that an error or exceptional condition has occurred during script execution. This allows you to gracefully handle errors by interrupting the normal flow of the program and providing a mechanism for error propagation.
To throw an exception in PHP, you use the throw
keyword followed by an object that represents the exception being thrown. Typically, you’ll use instances of the built-in Exception
class or its subclasses to represent different types of exceptions.
