This is exactly what try/catch is used for in PHP.I have been using try.catch blocks in my PHP code, but I'm not sure if I've been using them correctly. A catch block defines one or more types of exception or error it can handle, and optionally a variable to which to assign the exception. When writing PHP code, you’ll sometimes want to perform a certain action when an error is encountered (rather than just sending the user an error message and halting code execution). Linux is the system of choice for serving up your PHP code and is also an ideal PHP development environment. It means you can make the code execution continue even if errors are detected. This is useful for customizing how you display an error message to a user, or if you should potentially retry something that failed the first time. A PHP exception is a specified error that the system can catch and handle. This allows us to customize our code based on the type of exception that was thrown. Code may be surrounded in a try block, to facilitate the catching of potential exceptions. Once PHP has left the try block, it will not return to it. Exceptions can be attempting to read a file that doesn’t exist or connecting to the database server that is currently down. Here it checks each exception option against the list in catch and executes the appropriate code. Introduction to the PHP trycatch statement In programming, unexpected errors are called exceptions. In other words, you can 'try' to execute a block of code, and 'catch' any PHP exceptions that are thrown. PHP try catch with multiple exception types PHP supports using multiple catch blocks within try catch. An exception can be thrown, and caught (catched) within PHP. Summary: in this tutorial, you will learn how to use the PHP try.catch statement to handle exceptions. In a nutshell, the try-catch is a code block that can be used to deal with thrown exceptions without interrupting program execution. PHP is one of the most popular programming languages used to develop web applications and APIs. The primary method of handling exceptions in PHP is the try-catch.
