php - mysql_fetch_array() 执行无限循环

Question

我不知道为什么，一个应该是有限的循环，比如

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

正在执行无限循环，并且页面未加载...

为什么会这样？

Answer 1

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'];
    }

但mysql_*函数已弃用，因此请使用 pdo 或 mysqli

用pdo简单简单这里是很简单的pdo教程

$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);

Answer 2

尝试这个。

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