The Exception Class

The Exception class is the base class for all exceptions in PHP. It contains basic methods for working with exceptions: getting the error message, error code, file and line where the exception occurred, as well as the call stack. When creating an exception, you can pass a message, error code, and previous exception.

Syntax

new Exception(string $message = "", int $code = 0, Throwable $previous = null);

Example

Let's create and handle a simple exception:

<?php
	try {
		throw new Exception('Something went wrong', 100);
	} catch (Exception $e) {
		echo 'Error: ' . $e->getMessage();
	}
?>

Code execution result:

'Error: Something went wrong'

Example

Let's use the main methods of the Exception class:

<?php
	try {
		throw new Exception('Test exception', 123);
	} catch (Exception $e) {
		echo 'Message: ' . $e->getMessage() . "\n";
		echo 'Code: ' . $e->getCode() . "\n";
		echo 'File: ' . $e->getFile() . "\n";
		echo 'Line: ' . $e->getLine() . "\n";
	}
?>

Code execution result (example):

'Message: Test exception
Code: 123
File: /path/to/file.php
Line: 3'

Example

Let's get the call stack for an exception:

<?php
	function test() {
		throw new Exception('Stack trace test');
	}
	
	try {
		test();
	} catch (Exception $e) {
		print_r($e->getTrace());
	}
?>

Code execution result (example):

[
	[
		'file' => '/path/to/file.php',
		'line' => 5,
		'function' => 'test',
		'args' => []
	]
]
