mpdf - 如何使 mPDF 6.1 与 PHP 7.1.5 一起工作

Question

使用 PHP 5.6 在 WAMP 堆栈上开发，然后转移到 LAMP 7.1.5一切正常，除了 mPDF 6.1.0 提供以下内容:

Warning: A non-numeric value encountered in /var/sites/s/example.com/php_libs/vendor/mpdf/mpdf/mpdf.php on line 30648

Warning: A non-numeric value encountered in /var/sites/s/example.com/php_libs/vendor/mpdf/mpdf/mpdf.php on line 17074

Warning: A non-numeric value encountered in /var/sites/s/example.com/php_libs/vendor/mpdf/mpdf/mpdf.php on line 17075

Warning: A non-numeric value encountered in /var/sites/s/example.com/php_libs/vendor/mpdf/mpdf/mpdf.php on line 17093

我尝试了 Upgrade to PHP7.1 and MPDF show error - A non-numeric value encountered at line 30648 中提到的解决方案但这并没有解决它。

编辑mpdf.php，第89行，替换:

$errorlevel = error_reporting($errorlevel & ~E_NOTICE);

与:

$errorlevel = error_reporting($errorlevel & ~(E_NOTICE|E_WARNING));
