无语的出错,mysql_fetch_array()
代码如下，求帮忙看一下吧!
<?php
class Conn{
private $dbhost = "";//服务器
private $dbuser = "";//mysql帐号
private $dbpsw = "";//mysql密码
private $dbchar = "";//数据库编码类型
private $dbname = "";//数据库名称
private $tablepre = "";//表前缀
private $conn = NULL;//连接对象
/**
* 数据库链接初始化
*/
public function __construct(){
$this->getConn();
}
public function getConn(){
$db = require_once 'config/config.php';
$this->dbhost = $db['dbhost'];
$this->dbuser = $db['dbuser'];
$this->dbpsw = $db['dbpsw'];
$this->dbchar = $db['dbchar'];
$this->dbname = $db['dbname'];
$this->tablepre = $db['tablepre'];
$this->conn = mysql_connect($this->dbhost,$this->dbuser,$this->dbpsw) or die(mysql_error()."<br/>Mysql连接失败!");
mysql_select_db($this->dbname,$this->conn) or die(mysql_error()."<br/>数据库访问出错");
mysql_query("set names ".$this->dbchar,$this->conn);
}
/**
* 执行sql
*/
public function query($sql){
return mysql_query($sql,$this->conn) or die(mysql_error()."<br/>SQL执行出错：$sql");
}
/**
* 返回多条记录
*/
public function getDataArrays($sql,$type = MYSQL_BOTH){
$result = $this->query($sql);
$refArr = array();
while ($row = mysql_fetch_array($result,$type)){
$refArr[] = $row;
}
return $refArr;
}
/**
* 关闭数据库链接
*/
public function closeConn(){
mysql_close($this->conn);
}
}
$conn = new Conn();
$sql = "select * from qj_content";
$contentList = $conn->getDataArrays($sql,MYSQL_ASSOC);
$conn->closeConn();

[解决办法]
LZ看看W3C上面的例子吧
语法
mysql_fetch_array(data,array_type)
参数 描述
data 可选。规定要使用的数据指针。该数据指针是 mysql_query() 函数产生的结果。
array_type
可选。规定返回哪种结果。可能的值：
MYSQL_ASSOC - 关联数组
MYSQL_NUM - 数字数组
MYSQL_BOTH - 默认。同时产生关联和数字数组
<?php
$con = mysql_connect("localhost", "hello", "321");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
$db_selected = mysql_select_db("test_db",$con);
$sql = "SELECT * from Person WHERE Lastname='Adams'";
$result = mysql_query($sql,$con);
print_r(mysql_fetch_array($result));
mysql_close($con);
?>
public function query($sql){
$rs = mysql_query($sql,$this->conn) or die(mysql_error()."<br/>SQL执行出错：$sql");
return $rs;
}
