**Issue**
There is no easy way to catch PHP warnings, though some progress has been made in this area for PHP 8.0 (https://wiki.php.net/rfc/consistent_type_errors).
**Before**
```php
$file = file_get_contents('unknown.txt');
// PHP Warning: file_get_contents(unknown.txt): failed to open stream: No such file or directory
// workaround:
$file = @file_get_contents('unknown.txt');
if (false === $file) {
$e = error_get_last();
throw new \ErrorException($e['message'], 0, $e['type'], $e['file'], $e['line']);
}
```
**After**
```php
$file = ErrorHandler::call('file_get_contents', 'unknown.txt');
// or
$file = ErrorHandler::call(static function () {
return file_get_contents('unknown.txt');
});
// or (PHP 7.4)
$file = ErrorHandler::call(fn () => file_get_contents('unknown.txt'));
```
