php中addslashes数组递归转义例子
我们知道在php中addslashes函数是一个安全过滤函数,可以对接受到的变量进行转义以安全的入库了,但如果我们是以数组形式传参数过来,直接使用此函数无法进行操作了,下面我们一起来看看实现方法。
一、函数主要了addslashes 方法
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 (\)
•NULL
二、array_map 说明
array_map() 函数返回用户自定义函数作用后的数组。回调函数接受的参数数目应该和传递给 array_map() 函数的数组数目一致。
如果传递进来的参数 是数组形式则使用array_map方法进行参数的转义。
我们在开发对于$_GET,$_POST等变量
代码如下 | 复制代码 |
/** |
如果是数组将无法完成安全转义了,下面整理了一个例子,大家来看看
方法三,可以参考该递归方法实现其他功能,代码如下:
代码如下 | 复制代码 |
$arr = array('a"aa',array("c'd",array('e"f'))); Array ) ) |
原理是非常的简单,就是把数据利用foreach遍历一个个数组值进行操作了。
