The seven principles of PHP code specifications include consistency, readability, simplicity, reusability, testability, security and performance. Detailed introduction: 1. Consistency, the code should maintain consistency, that is, use the same naming convention, indentation style, code comments, etc. throughout the entire code base. This can make it easier for team members to understand and read the code, and reduce errors and confusion. Possibility; 2. Readability, the code should be easy to read and understand. In order to improve readability, you can use meaningful variable and function naming, avoid using overly complex expressions and nested structures, etc.

In PHP development, it is very important to follow good coding standards, which can improve the readability, maintainability and scalability of the code. The following are the seven principles of PHP code specifications:
1. Consistency: The code should maintain consistency, that is, use the same naming convention, indentation style, code comments, etc. throughout the code base. This makes it easier for team members to understand and read the code, reducing the chance of errors and confusion.
2. Readability: Code should be easy to read and understand. To improve readability, you can use meaningful variable and function names, avoid using overly complex expressions and nested structures, and use spaces, indentations, and blank lines to organize your code.
3. Simplicity: The code should be kept as simple as possible. Concise code is easier to understand and maintain, and reduces the possibility of errors. Code simplicity can be achieved by avoiding redundant code, using appropriate abstractions and design patterns, and following the single responsibility principle.
4. Reusability: Code should be highly reusable, that is, it can be reused in different scenarios and projects. In order to improve the reusability of code, commonly used functions can be encapsulated into functions or classes and placed in independent files so that they can be referenced and called when needed.
5. Testability: Code should be easy to test. Testable code makes it easier to perform unit testing, integration testing, and automated testing, thereby improving the quality and stability of your code. To improve code testability, you can use the design principles of dependency injection, decoupling, and modularity.
6. Security: The code should have certain security to prevent malicious attacks and data leakage. In order to improve the security of the code, you can use filtering and validating user input, avoid directly executing user-submitted code, use secure encryption algorithms, etc.
7. Performance: The code should have certain performance optimization. Performance optimization can improve code execution efficiency and response speed, and improve user experience. In order to improve the performance of the code, you can use appropriate data structures and algorithms, avoid repeated calculations and database queries, use cache appropriately, etc.
It should be noted that the above principles are not absolute, and specific coding specifications may vary depending on project needs, team agreements, and personal preferences. Therefore, in actual development, it is recommended to discuss and negotiate with team members to formulate code specifications suitable for the team.
To sum up, the seven principles of PHP code specifications include consistency, readability, simplicity, reusability, testability, security and performance. Following these principles can improve the quality, maintainability, and scalability of your code. If you have any further questions please feel free to let me know.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
