Make sure you establish a connection to your MySQL database first.

确保首先建立与MySQL数据库的连接。

$sql = "insert into yyy (id, twitterid, twitterkullanici, tweetsayisi, takipettigi, takipeden, nerden, bio, profilresmi, ismi) values ('', '$id', '$twk', '$tws', '$tkpettigi', '$tkpeden', '$nerden', '" . mysql_real_escape_string($bio) . "', '$img', '$isim')";

FYI, this could have easily been found with a Google search or using the PHP documention.

仅供参考，这可以通过Google搜索或使用PHP文档轻松找到。

Also, you should use this for any strings and/or user submitted data. Not just select fields.

此外，您应该将此用于任何字符串和/或用户提交的数据。不只是选择字段。

You don't. Start using parameterized queries with mysqli or better, PDO

你没有。开始使用mysqli或更好的PDO参数化查询

Example from the php doc with PDO :

来自PDO的php doc示例：

<?php
$stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (:name, :value)");
$stmt->bindParam(':name', $name);
$stmt->bindParam(':value', $value);

// insert one row
$name = 'one';
$value = 1;
$stmt->execute();

// insert another row with different values
$name = 'two';
$value = 2;
$stmt->execute();
?>
