最后一个查询失败，但所有其他查询都没问题。

错误是：

[08-Aug-2014 14:14:05 Europe/London] PHP Fatal error:  Call to a member 
function execute() on a non-object in /home/cufcstat/public_html/admin/ar.php
on line 317

我无法看到问题，有人可以吗？ SQL会停止执行代码，但对我来说SQL看起来是正确的吗？

对于凌乱的代码感到抱歉......

2 个答案:

答案 0 :(得分：1)

您在递增之前检查$i，因此您正在尝试准备一份不存在的声明

++$i; //returns the value of $i then increments it
$i++; //increments then returns

答案 1 :(得分：0)

问题是当骑车到我正在做的下一个玩家时停止重复SQL语句$ playerSQl =“”;但这是错误的，就好像一个sub没有出现它在$ sqlStatements中插入“”并尝试将该空间作为SQL查询执行。

相反，更改为$ playerSQL = null，并在插入数据库之前进行了检查以确保不是空值。
