php中foreach和list循环语句实例
文章重点讲到了关于foreach循环和list循环语句的用法,好了下面我们就来看实现吧,费话也不说多了有需要的同学可以参考一下。
最近买了本php和mysql web开发,看到数组循环语句。值得自己关注下,特此留点字迹,以便以后读阅。
一般foreach用的比较多
代码如下 | 复制代码 |
$price=array('apple'=>10,'orange'=>20,'banner'=>30); |
还有个更高级和常见的方法
代码如下 | 复制代码 |
$shuiguo=array('apple'=>10,'orange'=>20,'banner'=>30); |
以前还真没怎么关注下,今天自己动手,还不错,又了解新的东西了,还是自己太菜了,哎
list()函数可以用来一个数组分解成一系列的值,允许为新变量命名。不懂list的

两段代码输出是一样。
需要注意的是,当使用each()函数时候,数组将记录当前元素。如果希望在相同的脚本中使用两次该数组。就需要使用reset()降当前元素重新设置到数组开始处。
代码如下 | 复制代码 |
$price=array('apple'=>10,'orange'=>20,'banner'=>30); |
这样就可以依然使用数组$price咯。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3.
