我在使用 imagecreatefromjpeg 函数时遇到此错误。
Warning: imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Invalid SOS parameters for sequential JPEG in C:\wamp\www\test\index.php on line 7
我研究过，使用这个命令可以很好地传递错误，效果很好。
ini_set("gd.jpeg_ignore_warning", 1);
error_reporting(E_ALL & ~E_NOTICE);
但我想知道这是怎么回事？
这里是我的图片exif数据

最佳答案
你可以忽略这个错误
ini_set ('gd.jpeg_ignore_warning', 1);
(这是自 PHP 7.1 以来的默认设置，但在旧版本中不是)
关于php - 连续 JPEG 的 SOS 参数无效，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35337709/
