(PHP 4, PHP 5)
get_magic_quotes_runtime — 获取当前 magic_quotes_runtime 配置选项的激活状态
magic_quotes_runtime 在关闭时返回 0，否则返回 1。
自 PHP 5.4.0 起始终返回 FALSE。
| 版本 | 说明 |
|---|---|
| 5.4.0 |
总是返回 FALSE，因为魔术引号（magic quotes）功能已经从 PHP 中移除。

Example #1 get_magic_quotes_runtime() 例子
<?php
// 检测 magic_quotes_runtime 是否已经激活
if(get_magic_quotes_runtime())
{
// 关闭功能
set_magic_quotes_runtime(false);
}
?>

To add to what "php at nospam-qualystem dot com" has mentioned.
Some Japanese Encoding System (shift-jis) encode characters like 予 with ASCII pairs "975C". (5C is ASCII for backslash)
Thus when reading those characters from files (saved as shift-jis) in system with magic_quotes_runtime enabled, the characeter is turned into 予\ (equivalent ASCII "975C5C")
Similarly,
予定 is turned into 予\定

get_magic_quotes runtime and set_magic_quotes_runtime are useful when you want to read some data in a binary file using fread() and some bytes in such file may be interpreted as \ (backslash), " (double quotes), ' (simple quote) or any "special" character that has a meaning for string processing.
