php stripslashes() addslashes() 解析

stripslashes() 函数删除由 addslashes() 函数添加的反斜杠。

实例：

<?php
$str = "Is your name O\'reilly?";

// Outputs: Is your name O'reilly?
echo stripslashes($str);
?>

实例：

<?php
$str = "Who's John Adams?";
echo $str . " This is not safe in a database query.<br />";
echo addslashes($str) . " This is safe in a database query.";
?>

结果：

Who's John Adams? This is not safe in a database query.
Who\'s John Adams? This is safe in a database query.
