Question

我上线了我的网站。所有网站都运行良好，但有1页显示500 Internal Server Error。

你能告诉我为什么吗？

这是我的控制器。

您在代码中使用短数组标记进行制作。

<?php echo form_upload(['name' => 'image', 'id' => 'image']); ?>

你只需简单地使用：

<?php echo form_upload(array('name' => 'image', 'id' => 'image')); ?>

您的PHP版本不允许您使用php短标记数组。

<强>更新

添加@Simba的评论：您需要升级你的php版本紧急 - 短阵列格式一直存在 PHP 5.4。如果你的php不支持它，那就意味着你正在使用它非常古老且不受支持的版本。您需要升级才能避免安全问题。能够使用像短的现代PHP功能数组格式将是一个奖金，但运行安全的担忧旧版应该更重要。
