为什么我显示这个这个错误?
( ! ) Parse error: syntax error, unexpected 'foreach' (T_FOREACH) in D:\wamp\www\cxblog.php on line 4
这个查询出来是个数组吗?我只想把数据库里面的值取出来 不要数组形式的 应该怎么写呢
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
$sql=$pdo->query('select * from blog')
foreach($sql as $row){
print_r($row);
}
?>
回复讨论(解决方案)
PDOStatement PDO::query ( string statement )
mixed PDOStatement::fetch ( [int fetch_style [, int cursor_orientation [, int cursor_offset]]] )
array PDOStatement::fetchAll ( [int fetch_style [, int column_index]] )
PDOStatement PDO::query ( string statement )
mixed PDOStatement::fetch ( [int fetch_style [, int cursor_orientation [, int cursor_offset]]] )
array PDOStatement::fetchAll ( [int fetch_style [, int column_index]] )
英文的看不懂
PDOStatement PDO::query ( string statement )
mixed PDOStatement::fetch ( [int fetch_style [, int cursor_orientation [, int cursor_offset]]] )
array PDOStatement::fetchAll ( [int fetch_style [, int column_index]] )
我知道问题了 我前面$sql没有加结束的分号 现在显示出来的是一个数组 但是我只想要数据
改成这样.
<?php $pdo=new PDO("mysql:host=localhost;dbname=t1","root",""); $sth=$pdo->query('select * from blog') $result = $sth->fetchall(PDO::FETCH_ASSOC); foreach($result as $k=>$v){ print_r($v);}?>
改成这样.
<?php $pdo=new PDO("mysql:host=localhost;dbname=t1","root",""); $sth=$pdo->query('select * from blog') $result = $sth->fetchall(PDO::FETCH_ASSOC); foreach($result as $k=>$v){ print_r($v);}?>
试了一下提示这个错误 怎么回事?
( ! ) Parse error: syntax error, unexpected '$result' (T_VARIABLE) in D:\wamp\www\cxblog2.php on line 4
改成这样.
<?php $pdo=new PDO("mysql:host=localhost;dbname=t1","root",""); $sth=$pdo->query('select * from blog') $result = $sth->fetchall(PDO::FETCH_ASSOC); foreach($result as $k=>$v){ print_r($v);}?>
这样得到的还是数组形式的 我只想得到值
当然是数组形式的!
你 select * from blog
这个 * 表示的是表中的所有字段,php 不可能越俎代庖的将他们链接成一个值
即便表中只有一个字段,但 php 也是不会知道的
因为所有的解释权在你,而不是在 php

我这个表只有一列就是content列 我改成select content from blog 还是不行啊
我已经说过了,php 对于数据库查询,总是返回数组的
$pdo=new PDO("mysql:host=localhost;dbname=t1","root",""); $sth=$pdo->query('select * from blog') $result = $sth->fetchall(PDO::FETCH_ASSOC); foreach($result as $k=>$v){ echo $v['content']; //这样不就是但值了吗?}

哦哦可以了 谢谢 我再好好看看
