php http请求非法偏移量

php http请求非法偏移量,php,mysql,Php,Mysql,我正在尝试制作一个php脚本,它允许http请求将某些数据插入数据库。我对此有3个文件: Database.php Record.php 和Test.php 我试图发送以下请求: 这给我带来了以下错误消息: 警告:中的字符串偏移量“Naam”非法 /mnt/web106/b1/74/58274074/htdocs/school/fontyskart/php/test.php on 第25行警告:中的非法字符串偏移量“Eindtijd” /mnt/web106/b1/74/58274

我正在尝试制作一个php脚本,它允许http请求将某些数据插入数据库。我对此有3个文件:

Database.php


Record.php


Test.php


我试图发送以下请求:

这给我带来了以下错误消息:

警告:中的字符串偏移量“Naam”非法 /mnt/web106/b1/74/58274074/htdocs/school/fontyskart/php/test.php on 第25行警告:中的非法字符串偏移量“Eindtijd” /mnt/web106/b1/74/58274074/htdocs/school/fontyskart/php/test.php on 第26行警告:中的非法字符串偏移量“Tijdstip” /mnt/web106/b1/74/58274074/htdocs/school/fontyskart/php/test.php on 第27行{“消息”:“产品已创建”}

如您所见:它确实在数据库中创建了一个产品,但它们只是空记录


因为我是PHP新手,我真的不知道我做错了什么。任何能帮我解决这个问题的人?

file\u get\u contents都无法获取发布的数据。阅读该功能的文档。我不知道你从哪里得到这样的想法,它会做你所期待的。你在网上找不到它的任何例子,教程,文档中没有任何能给你这种印象的东西。是什么让你决定试试这个??它将发出一个新的HTTP请求,并以文本而不是数组的形式从调用该URL返回响应。要获取发布到脚本中的数据,您要做的是从$\u POST数组中读取数据。世界上的每一个PHP教程都会向您展示这一点。
