mysql_escape_string

(PHP 4 >= 4.0.3, PHP 5)

mysql_escape_string — 转义一个字符串用于 mysql_query

说明

mysql_escape_string(string $unescaped_string): string

本函数将 unescaped_string 转义，使之可以安全用于 mysql_query()。

注意: mysql_escape_string() 并不转义 % 和 _。本函数和 mysql_real_escape_string() 完全一样，除了 mysql_real_escape_string() 接受的是一个连接句柄并根据当前字符集转移字符串之外。mysql_escape_string() 并不接受连接参数，也不管当前字符集设定。

示例 #1 mysql_escape_string() 例子


<?php
    $item = "Zak's Laptop";
    $escaped_item = mysql_escape_string($item);
    printf ("Escaped string: %s\n", $escaped_item);
?>

以上例子将产生如下输出：

Escaped string: Zak\'s Laptop

参见 mysql_real_escape_string()，addslashes() 和 magic_quotes_gpc 指令。

You can use this function safely with your MySQL database queries if and only if you are sure that your database connection is using ASCII, UTF-8, or ISO-8859-* and that the backslash is your database's escape character. If you're not sure, then use mysqli_real_escape_string instead. This function is not safe to use on databases with multi-byte character sets.

The only benefit of this function is that it does not require a database connection.
