Home Backend Development PHP Tutorial 经常忘掉函数参数位置

经常忘掉函数参数位置

Jun 23, 2016 pm 02:09 PM

PHP函数不少。
有些函数参数有几个,函数倒是知道,
但过一段时间,老是忘了函数参数位置。

如 strpos(string, find)
还是
strpos(find, string)
等等……


大家有没这样的情况? 


回复讨论(解决方案)

有的,很正常的。php那么多函数都记得那么清楚太难了,反正我是做不到的。
不过没关系,知道函数名字查下就可以了。

太正常不过了!
一般不使用不熟悉的函数,万不得已时就查查手册
不过测试一下也是常有的
echo strpos('abcd', 'c'),':',strpos('c','abcd');
谁对就用谁

原来大家都会这样啊。
php一步一步过来都没考虑到这一点呢,

如果主体都能放首位,
类似参数位置都能这样就好了 = =...
strpos(string, find)
str_replace(string, find, replace)
in_array(array, value)
...

主要是因为有一些函数是直接源于 C 库,没有重载机制,所以换不过来
加上扩展都是由不同的php爱好者们独立书写的,必然留下来他们自己的习惯

解决同一的唯一方法就是放弃对库函数的支持,而一律改为对象
不过这就不是 php 而是 java 了

也是,估计没方法了。

en, 是可以自己定义一对象使用__call
全部重写原函数……,不过也只是闹着玩了

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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. 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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
