Foreach显示数据两次 [英] Foreach displaying data twice

问题描述

我必须遗漏一些相当明显的东西。我有以下

代码片段，当它应该只回显一次（数组中只有一个元素）时，它回显'我的结果两次。我在俯瞰什么？

********************************

$ OpenQ = mysql_query（" SELECT column FROM table WHERE q_uid =

$ _SESSION [userid] AND status = 1"，$ db）; // DB上的SQL查询返回1

结果


$ Qresult = mysql_fetch_array（$ OpenQ）; //获取数组


if（$ _GET [''OQ'']）{//如果收到get变量

foreach（$ Qresult作为$ Q）{

echo"< br>" 。 $ Q;

}

}


***************** ****************


TY。

解决方案

OpenQ = mysql_query（" SELECT column FROM table WHERE q_uid =

_SESSION [userid] AND status = 1"，

分贝）; // DB上的SQL查询返回1

结果

I must be missing something rather obvious. I have the following
snippet of code that echo''s my result twice when it should be echoing
just once (only one element in the array). What am I overlooking?
********************************
$OpenQ = mysql_query("SELECT column FROM table WHERE q_uid =
$_SESSION[userid] AND status = 1",$db); // SQL query on DB returns 1
result

$Qresult = mysql_fetch_array($OpenQ); // Fetch the array

if ($_GET[''OQ'']) { // If the get variable is recieved
foreach ($Qresult as $Q) {
echo "<br>" . $Q;
}
}

*********************************

TY.

解决方案

OpenQ = mysql_query("SELECT column FROM table WHERE q_uid =

_SESSION[userid] AND status = 1",

db); // SQL query on DB returns 1
result
