搜索数组 [英] Searching through an array

问题描述

我创建了一个数组，但我需要搜索它。从mysql调用创建数组
。代码如下：


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

函数respond_check（$ qid）

{

包括db.inc.php;

$ postchk2 = mysql_query（" SELECT * FROM`answer`，`users`在哪里`qid`

= $ qid AND`a_uid` =`userid` LIMIT 0,30"，$ db）;


while（$ userx = mysql_fetch_array（$ postchk2））

{

$ poster2 = $ u_row22 [''username''];

}
< br $>
}


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

我已经尝试包括各种* if *语句来搜索

数组中的$ X（确实存在），但我一直惨遭失败。建议？

I have an array created but I need to search it. The array is created
from a mysql call. Code as follows:

******************
function respond_check($qid)
{
include "db.inc.php";
$postchk2 = mysql_query("SELECT * FROM `answers` , `users` WHERE `qid`
= $qid AND `a_uid` = `userid` LIMIT 0, 30",$db);

while ($userx=mysql_fetch_array($postchk2))
{
$poster2 = $u_row22[''username''];
}

}

******************
I''ve tried including various *if* statements to search for $X in the
array (which does exist) but I keep failing miserably. Suggestions?

推荐答案

qid）

{

包括db .inc.php" ;;

qid)
{
include "db.inc.php";

postchk2 = mysql_query（" SELECT * FROM`answer`，`users` WHERE`qid`

=

postchk2 = mysql_query("SELECT * FROM `answers` , `users` WHERE `qid`
=

qid AND`a_uid` =`userid` LIMIT 0,30"，

qid AND `a_uid` = `userid` LIMIT 0, 30",
