上载产品php脚本不工作

我创建了一个

Php

脚本来将产品上传到我的网站，但它不起作用，也没有显示任何错误。我被这个问题困扰了5天多，我仍然在寻找错误，但我不能请任何人检查我的代码，我需要立即帮助

您可以检查几件事情来确保这一点。因为这是一个文件资源，所以您也必须考虑代码之外的内容。我知道在过去的5天里，您已经做了大量的研发工作，可能已经完成了下面提到的所有步骤，但请再试一次。我希望它能解决你的问题

您上载的位置是否具有适当的写入权限
使错误报告在代码顶部可用
无论在何处使用move\u上传的\u文件，都要创建错误日志
使用断点检查您的代码是否到达代码的上载点
正如在您的问题评论中所说的，检查move_上传的文件函数返回的内容

php\上传值\最大\文件大小=16G

php_值post_max_size=16G

php_值最大输入时间3600

php_值最大执行时间3600

在.htaccess中输入此代码，并根据需要更改值。
检查move_upload_file函数返回的值（真/假）。其中@Param Bhat//上载文件并插入数据库move_upload_file（$tmpLoc，$uploadPath）；=>如果文件正在上载或未上载，请选中此行。添加if（move_uplated_file（$tmpLoc，$uploadPath））{echo“true”；}否则{echo“false”；}您正在使用此函数move_uplated_file，因此将其放入如下变量$abc=move_uplated_file（src，dest）；然后打印这张$abc来检查它返回的内容。它不工作了。
