php - 我在 postgresql 中的表正在截断这些字符串

Question

我在 VMobjects 中有一个这样的表

MGRCONFIG_DB=# select * from vmobjects;
               guid                |   ipaddress   | username | password |  hostid  |     vmname      | guestostype | guestos

现在我有一个 php 页面 addvm.php，当我添加 username/ip/password/ 或任何它被截断的内容时

gets truncated on entering data as '~!@#$%^&*()_+=-`{}|\][:"';<>?/.,' for all fields.

使用后pg_escape_string 我可以插入 '~!@#$%^()_=-`{}|][:"';<>?/. 除了 + 和 & 之外的所有字符串。 @Emil Vikström:说我必须为此使用 urlencode。但我不知道，它是如何使用的？

Answer 1

使用pg_escape_string在将数据输入 SQL 查询之前对数据进行处理:

$data = '~!@#$%^&*()_+=-';
$data_escaped = pg_escape_string($data);
$query = 'INSERT INTO table (data) VALUES("'. $data_escaped .'");';
