Thesis Exceptionally

A tiny PHP library that converts errors to exceptions.

Installation

composer require thesis/exceptionally

Requires PHP 8.3+.

Usage

use function Thesis\exceptionally;

// Converts PHP errors to ErrorException
$content = exceptionally(static fn() => file_get_contents('/path/to/file'));

Many PHP functions trigger errors instead of throwing exceptions. This makes error handling inconsistent and cumbersome. exceptionally() wraps a callable and converts any triggered error into a native ErrorException.

Error suppression operator

Errors suppressed with @ are not converted to exceptions:

// Does not throw — the error is suppressed
$content = exceptionally(static fn() => @file_get_contents('/path/to/file'));

Filtering by error level

By default, all levels except E_DEPRECATED and E_USER_DEPRECATED are converted. Deprecations typically come from third-party libraries and should not interrupt execution.

You can specify which levels to convert:

// Convert notices
$result = exceptionally($function, E_USER_NOTICE);

// Convert warnings and notices
$result = exceptionally($function, E_USER_WARNING | E_USER_NOTICE);

// Convert all, including deprecations
$result = exceptionally($function, E_ALL);
