PHP升级到7.2后，laravel/mPDF非数字值遇到ErrorException [英] Laravel/mPDF non-numeric value encountered ErrorException after PHP upgrade to 7.2

问题描述

我将php7.1更新为php7.2.1(PHP 7.2.1(cli))，但未生成laravel pdf，显示在错误提示下:

(1/1) ErrorException

A non-numeric value encountered
in mpdf.php (line 30648)

at HandleExceptions->handleError(
    2, 
    'A non-numeric value encountered', 
    '/opt/lampp/htdocs/mysite/vendor/mpdf/mpdf/mpdf.php', 
    30648, 
    array(
        'size' => 0, 
        'maxsize' => 190.00155555555551245561218820512294769287109375, 
        'fontsize' => 3.704166666666667051543981870054267346858978271484375,
        'usefontsize' => false)
    )
in mpdf.php (line 30648)

解决方案

基于错误消息，您正在使用与PDF 7.2不兼容的mPDF 6.x(在此问题上也不完全与PHP 7.1兼容). /p>

您应升级到mPDF 7 (PHP 7.2之前一直受官方支持).

I update php7.1 to php7.2.1 (PHP 7.2.1 (cli)) my laravel pdf not generated show below errorr:

    )
in mpdf.php (line 30648)

解决方案

Based on the error message, you are using mPDF 6.x which is not compatible with PHP 7.2 (and not entirely with PHP 7.1 for that matter).

You should upgrade to mPDF 7 which is officially supported up to PHP 7.2.
