<?php
// 创建临时文件指针
$fp = tmpfile();
// 写入一些数据
fwrite($fp, '\'PHP\' is a Recursive acronym');
// 没有 magic_quotes_runtime
rewind($fp);
set_magic_quotes_runtime(false);
echo 'Without magic_quotes_runtime: ' . fread($fp, 64), PHP_EOL;
// 有 magic_quotes_runtime
rewind($fp);
set_magic_quotes_runtime(true);
echo 'With magic_quotes_runtime: ' . fread($fp, 64), PHP_EOL;
// 清理
fclose($fp);
?>

Be aware that even using ini_set to set 'magic_quotes_runtime' will stop working in PHP 5.4. See http://php.net/manual/en/info.configuration.php#ini.magic-quotes-runtime

You should NEVER rely on magic quotes or addslashes for security in an SQL context. You should ALWAYS use proper escape functions, such as mysql_real_escape_string. Failure to do so may result in an SQL injection vulnerability.

Since this function is depracted as of PHP 5.3, use ini_set('magic_quotes_runtime', 0); instead.

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.
