In previous PHP versions, if we wanted to catch an exception, then we needed to store it in a variable to check if the variable was used.
Before PHP 8, in order to handle exception catching blocks, we needed to catch the exception (thrown by the try block) into a variable.
Example: Catching exceptions in PHP
<?php
function foo()
{
try{
throw new Exception('Hello');
}
catch (Exception $e) {
return $e->getMessage();
}
}
?>Explanation − In the above program, the exception is caught by the catch block into a variable $e. Now the $e variable can save any information about the exception, such as code, message, etc.
PHP 8Introduced non-capturing catch. It is now possible to catch exceptions without capturing them in variables. We can ignore this variable for now.
Example: Non- Capturing Exception Catches in PHP 8
<?php
try{
throw new Exception('hello');
}
catch (Exception) { // $e variable omitted
}
?>Note: In the above program, we did not use the $e variable to save Exception information.
