PHP is known as the general purpose programming language. It is used as a server-side scripting language that is mainly used for the development of web sites. The PHP frameworks also make web development easier. This framework helps in reusing the same code and there is no need to write the lengthy and complex code for the web applications. PHP frameworks are mainly open source and can be used easily. It was developed by Rasmus Lerdorf and it was developed in the year 1994. PHP was written in C language primarily but some of the components were written in C++ language as well.

Advantages of PHP
Following are the top 10 advantages of PHP which are as follows:
1. Open Source
PHP is open-source and free of cost, which helps developers to install it quickly and readily available for use. There are a lot of PHP frameworks and developer can choose any of the frameworks to work. All the features and tools will be provided to the developer for that framework easily. As it is open-source, it makes the system ready with PHP in quick time and makes the web development faster with the help of providing the tools and other features easily.
2. Platform Independent
PHP is mainly supported by all the operating systems like Windows, Unix, Linux etc. The PHP based developed web applications can be easily run on any platform. It can be integrated with other programming language and database easily and there is no requirement of re-development. It helps in saving a lot of effort and cost.
3. Simple and Easy
This advantage of PHP is simple and easy to learn and code. It is mainly organized code and clean, which helps the new developers also. The command functions of PHP can easily learn and understood. The one who knows any programming language can easily work on PHP. It is simple to learn, as its learning curve is not large. The syntax is simple and flexible to use.
4. Database
PHP is easily connected with the database and make the connection securely with databases. It has a built-in module that is used to connect to the database easily. There are many web applications, which require strong programming language with a good database management system. PHP and its database connection solve the purpose for development of web applications. It reduces the time to connect to a database management system as well. Multiple databases can be integrated with PHP.
5. Fast
PHP is known as the fastest Programming language as compared to another. PHP applications can be easily loaded over the slow Internet and data speed. Other applications take a lot of time to connect the database and fetch the data after executing certain queries to the database. PHP does not face this problem and it loads the website very easily and fast. The fast speed of PHP provides the developer with an edge to develop the web applications in PHP programming language.
6. Maintenance
PHP framework is mainly used to make the web application development easier and maintain the code automatically. The model view controller architecture in PHP framework helps the code to be easily maintained and used. The MVC architecture helps the separation of a file for different module separately.
7. Support
This advantage of PHP has great online support and community, which helps the new developers to help in writing the code and developing the web applications. The documentation provided at the official site helps in using the different features of PHP and its framework. The latest updates are released timely by the PHP to make it better for the developer to develop the web-based applications.
8. Testing
PHP based web applications can be easily tested. PHP unit uses to perform the unit testing quickly and easily. It also helps the programmers to write test cases and perform the testing smoothly. For PHP based web applications, the developers do not need to write the additional code. PHP frameworks help in automating the different tasks.
9. Security
PHP frameworks built-in feature and tools make it easier to protect the web applications from the outer attacks and security threats. The security threats can be like SQL injection, data tampering, and forgery etc. To protect from these security threats, developers used PHP frameworks for developing web applications.
10. Stable
PHP is also stable as compared to other programming languages. It has been in existence for a long time. The developers have worked on PHP to make it easy for the programmers to work on developing the PHP web-based applications. They have fixed the issues and bugs over the period of time for the different version of PHP and make it very stable.
Conclusion
PHP has a lot of advantages and some are described above. It has disadvantages as well but it is still better than other programming languages. It is being widely used the programming language and many people are using this programming language for creating the different types of web-based application. It is used because of its features and open source. It does not cost and able to develop the customized application integrated with other programming languages as well.

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。

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。

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。

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.
