错误信息

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in C:\Apache\htdocs\growers\news.php on line 147

回复讨论(解决方案)

$sql = mysql_query("select * from frontpagenews where identification = ".$_GET['identification']." order by createDate desc limit 0,7");

 mysql_query("select * from frontpagenews where identification = ".$_GET['identification']. "order by createDate desc limit 0,7");
除非 $_GET['identification'] 最后的字符是空格,不然 $_GET['identification'] 的值不就和 order 连在一起了?
如果 $_GET['identification'] = 1
你的 sql指令不就了
"select * from frontpagenews where identification = 1order by createDate desc limit 0,7"
吗?

粗心要人命啊。多谢了。少个空格

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
