mysql_fetch_array（）这样无限循环

Question

我不知道为什么，一环，应该是有限的，像

while ($noticia = mysql_fetch_array(mysql_query("SELECT * FROM noticias WHERE deletada='0' ORDER BY id ASC"))) 
{ 
    // echo $noticia['blabla']; 
} 

正在做无限循环，并在页面没有加载...

为什么会发生？

Answer 1

尝试。

$query = mysql_query("SELECT * FROM noticias WHERE deletada='0' ORDER BY id ASC"); 
while($noticia = mysql_fetch_array($query)){ 
    echo $noticia['table_field']; 
} 

Answer 2

它可以通过

$qry = mysql_query("SELECT * FROM noticias WHERE deletada='0' ORDER BY id ASC") 

    while ($noticia = mysql_fetch_array($qry)) 
    { 
     // echo $noticia['blabla']; 
    } 

来解决，但mysql_*函数已不再那么请使用PDO或mysqli的

与PDO一个简单的简单here is very simple pdo tutorial

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=UTF-8', 'username', 'password'); 
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false); 

$query = $pdo->prepare("SELECT * FROM noticias WHERE deletada='0' ORDER BY id ASC"); 
$query->execute(); 
$row=$articlequery->fetch(pdo::FETCH_ASSOC);
