Handling errors in PHP is almost the same as handling errors in other programming languages.
When we say error handling we are referring to the process of catching errors produced by your program which needs proper action.
It is used to change the usual way of handling code execution of a specific error condition when it occurs.
In this way, exception handling provides a better technique over error handling.
It’s pointless that the application continue executing because it would not still return some data from the database.
During development, using the function die or exit to halt code is a go-to-coding style for developers.
When a PHP exception is thrown, the PHP runtime looks for a catch statement that can handle that type of exception.
If one is not found, the exception is handed to the global exception handler that we will also cover in this article.
// run your code here
//code to handle the exception
//optional code that always runs
The following keywords are used for PHP exception handling.

When an error occurs the PHP script displays a fatal error. For avoiding the error, one should write the code properly for handling the exception in the PHP script. The PHP exception handler is a clever way of managing the exceptional condition.

try {
// Some code
} catch (Exception $e) {
echo ‘Message: ‘ . $e->getMessage();
}

3. array_key_exists() vs in_array()
If you are using array_key_exists() instead of in_array(), believe it or not, it is a good choice you made. array_key_exists() is much faster than in_array().
array_key_exists($key, $array); // ideal
in_array( $key, array_keys( $array ) ) // This creates an array of keys from the given array first, which makes it much slower than array_key_exists()
4. unserialize() vs json_decode()
Try to avoid using unserialize, use json_decode instead. The main difference between the two is the fact that unserialize is much more dangerous if used for data received from the network.
