PHP空白页面。 [英] PHP Blank Page.

问题描述

好的，


我之前发布的这是一个空白的php页面。我已经在php.ini中启用了日志记录

ALL，但没有。如果我在

中更改包含文件的数据库名称，我会收到一条错误消息，所以我猜这意味着它是连接到mysql数据库的
。我已经为这个页面添加了几行

代码：


index.php

<？php

session_start（）;

require_once（''inc / db_config.inc.php''）;

$ conn = db_connect（）;

$ sqlsu =" SELECT * FROM subject ORDER BY ID" ;;

$ ressu = mysql_query（$ sqlsu，$ conn）;

if（mysql_num_rows（$ ressu））{

while（$ qry = mysql_fetch_array（$ ressu））{

$ cat = stripSlashes（$ qry [''cat'' ]）;

$ resns = mysql_query（" SELECT * FROM questions WHERE test LIKE''$ cat''"，

$ conn）;

$ numcat = mysql_num_rows（$ resns）;


inc / db_config.inc.php

函数db_connect（）

{

$ result = @mysql_pconnect（''localhost''，''root''，''密码）;

if（！$ result）

返回false;

if（！@mysql_select_db（''quiz''））

返回false;


返回$ result;

}

Ok,

I posted earlier about this, a blank php page. I''ve enabled logging
ALL in the php.ini, but nothing. If I change the name of the db in
the include file, I get an error message, so I guess this means it''s
connecting to the mysql db. I''ve included the first couple lines of
code for this page:

index.php
<?php
session_start();
require_once(''inc/db_config.inc.php'');
$conn = db_connect();
$sqlsu = "SELECT * FROM subjects ORDER BY ID";
$ressu = mysql_query($sqlsu, $conn);
if (mysql_num_rows($ressu)) {
while ($qry = mysql_fetch_array($ressu)) {
$cat = stripSlashes($qry[''cat'']);
$resns = mysql_query("SELECT * FROM questions WHERE test LIKE ''$cat''",
$conn);
$numcat = mysql_num_rows($resns);

inc/db_config.inc.php
function db_connect()
{
$result = @mysql_pconnect(''localhost'', ''root'', ''password);
if (!$result)
return false;
if (!@mysql_select_db(''quiz''))
return false;

return $result;
}
?>

推荐答案

conn = db_connect（）;

conn = db_connect();

sqlsu =" SELECT * FROM subject ORDER BY ID" ;;

sqlsu = "SELECT * FROM subjects ORDER BY ID";

ressu = mysql_query（

ressu = mysql_query(
