使用PDO回显表中的所有行 [英] Using PDO to echo display all rows from a table

问题描述

我正在尝试使用PDO回显表的所有行，但遇到麻烦了.

I'm trying to echo out all the rows of a table using PDO but am running into trouble.

使用旧的方式，我会像这样

With the old way of doing I'd have done it like

$result = mysql_query($sql);
while ($row = mysql_fetch_array($result)){
   $title= $row['title'];
   $body= $row['body'];
}

但是我正在尝试PDO；

But with PDO I'm trying;

$result = $db->prepare("SELECT title, body FROM post");
$result->execute();

while ($row = $db->fetchAll(PDO::FETCH_ASSOC))
{
$title = $row['title'];
$body = $row['body'];
}

echo $title;
echo $body;

哪个一直给我打电话给未定义的方法PDO :: fetchAll()

Which keeps giving me Call to undefined method PDO::fetchAll()

按照手册中的示例进行操作

Doing the example given in the manual

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();

/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll();
print_r($result);
?>

有效，但是我不认为我可以像$ row = ['blah']那样控制各个列.可以吗它也像这样打印出来；相当丑陋:

Works, but I don't think I have control over the individual colums like I would with a $row=['blah']; do I? It also prints out like this; rather ugly:

Array([0] => Array([title] =>这是在数据库中输入的测试标题[0]

Array ( [0] => Array ( [title] => This is the test title entered in the database[0]

要正确使用PDO来做到这一点需要做些什么?

What needs to be done to properly use PDO to do this?

推荐答案

更改:

while ($row = $db->fetchAll(PDO::FETCH_ASSOC))
{
$title = $row['title'];
$body = $row['body'];
}

收件人:

while ($row = $result->fetch(PDO::FETCH_ASSOC))
{
$title = $row['title'];
$body = $row['body'];
}
