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);
?>
输出：
Who's John Adams?
addslashes() 函数在指定的预定义字符前添加反斜杠。
这些预定义字符是：
- 单引号 (')
- 双引号 (")
- 反斜杠 (\)
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.
