正从数据库和PHP

我正在做的API来简单的论坛信息,, 现在试图从数据库中的信息，并显示在控制页面上正从数据库和PHP

： showForums.php

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<title>TheForums</title> 
</head> 
<body> 

<?php 
error_reporting(E_ALL); 
ini_set('display_errors', 1); 

require_once('fourmsAPI.php'); 
/* 
function tinyf_forums_get($extra ='') 
{ 
    global $tf_handle; 
    $query = sprintf("SELECT * FROM `forums` %s",$extra); 
    $qresult = mysqli_query($tf_handle, $query); 

    if (!$qresult) 
     return NULL; 
    $recount = mysqli_num_rows($qresult); 
    if ($recount == 0) 
     return NULL ; 
    $forums = array(); 
    for($i = 0 ; $i < $recount ; $i++) 
     $users[count($forums)] = mysqli_fetch_object($qresult); 
    //mysql_free_result($qresult); 

    return $forums; 

} 
*/ 
$forums = tinyf_forums_get(); 
if($forums == NULL) 
{ 
    die('problem'); 
} 
$fcount = count($forums); 
if($fcount == 0) 
{ 
    die('No Forums '); 
} 
?> 

<ul type = "square"> 
<?php 
for($i = 0 ; $i < $ucount ; $i++) 
{ 
    $forum = $forums[$i]; 
    echo "<li><a href = \"forums.php?id=$forum->id\"> $forum->title <a/> <br/> $forum->desc <br/> </li>"; //$array -> 

} 
?> 
</ul> 

</body> 
</html>

结果===> '问题'

我预计它会显示信息

我认为功能tinyf_forums_get（）是造成该

您的代码被打破：

你定义一个数组，那么千万不要使用它：

$forums = array(); 

    $users[count($forums)] = mysqli_fetch_object($qresult); 
    ^^^^^---undefined, never returned, never used otherwise, therefore useless. 

return $forums; 
     ^^^^^^---returning permanently empty array

a第二，因为$forums是一个空数组：

php > $x = array(); 
php > var_dump($x == null); 
bool(true)

你可能想

if (count($forums) == 0)

代替。

是的，真的非常感谢，因为我从用户的api复制了一些功能。另一个API文件 – smile
