php新人入门问题请教
一直在做Java的开发,现在因为要帮朋友搞个Wordpress,所以想就php的问题向各位请教下,
1. Java中有容器,如List, Map, php 是否也有类似的东西?
2. 比如对象排序的问题,用java可以写比较器Comprator进行排序; php是否也有类似的对象排序的功能?

各位对学习Php有什么好的建议,或是经验,书籍的推荐;也一并感激!


------解决方案--------------------
php最好的书是官方手册
http://www.php.net/manual/en/
------解决方案--------------------
有java 基础很快上手啦,看下楼上的手册. 不用几天就行了.主要要适应一下php的规范
------解决方案--------------------
实践...
------解决方案--------------------
1.php就一个数组,想怎么揉捏就怎么揉捏,php的特性之一就是强大灵活的数组,不管你什么ArrayList,HashMap到php手里都是一个样,就是数组。
2.这个倒没有,不过你可以实现,只要搞清楚两个对象之间如何判定大,小,等于关系即可。
------解决方案--------------------
粗略的说
java 源于 c++ 在面向对象方面高于 c++
php 源于 c 介于 c、c++ 之间

如果你不习惯面向过程,最好还是少沾

When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections.

Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
