PHP的另一个问题 [英] Another Problem With PHP

问题描述

警告:mysql_fetch_assoc()期望参数1为资源，在第21行的C:\ Program Files \ xampp \ htdocs \ ZA_Kamez \ include.php中给出布尔值

此错误是什么意思?

Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in C:\Program Files\xampp\htdocs\ZA_Kamez\include.php on line 21

What does this error mean??

<?php
include 'blogpost.php';

$connection = mysql_connect('localhost', 'login_h', '1234') or die ("<p class='error'>Sorry, we were unable to connect to the database server.</p>");
$database = "articles";
mysql_select_db($database, $connection) or die ("<p class='error'>Sorry, we were unable to connect to the database.</p>");

function GetBlogPosts($inId=null, $inTagId =null)
{
	$query = null;
	if (!empty($inId))
	{
		$query = mysql_query("SELECT * FROM blog_posts WHERE id = " . $inId . " ORDER BY id DESC"); 
	}
	else
	{
		$query = mysql_query("SELECT * FROM blog_posts ORDER BY id DESC");
	}
	
	$postArray = array();
	while ($row = mysql_fetch_assoc($query))
	{
		$myPost = new BlogPost($row["id"], $row['title'], $row['post'], $row['postfull'], $row["author_id"], $row['date_up']);
		array_push($postArray, $myPost);
	}
	return $postArray;
}
?>

推荐答案

连接 = mysql_connect(' localhost'，' ' 或死亡( < p class ='error'>很抱歉，我们无法</p>")；

connection = mysql_connect('localhost', 'login_h', '1234') or die ("<p class='error'>Sorry, we were unable to connect to the database server.</p>");

数据库 = " ; mysql_select_db(

database = "articles"; mysql_select_db(

数据库，
