/** * 判断字符串是否符合手机号码格式 * 移动号段: 134,135,136,137,138,139,147,150,151,152,157,158,159,170,178,182,183,184,187,188 * 联通号段: 130,131,132,145,155,156,170,171,175,176,185,186 * 电信号段: 133,149,153,170,173,177,180,181,189 * @param str * @return 待检测的字符串 */
public static boolean isMobileNO(String mobileNums) { /** * 判断字符串是否符合手机号码格式 * 移动号段: 134,135,136,137,138,139,147,150,151,152,157,158,159,170,178,182,183,184,187,188 * 联通号段: 130,131,132,145,155,156,170,171,175,176,185,186 * 电信号段: 133,149,153,170,173,177,180,181,189 * @param str * @return 待检测的字符串 */ String telRegex = "^((13[0-9])|(14[5,7,9])|(15[^4])|(18[0-9])|(17[0,1,3,5,6,7,8]))\\d{8}$";// "[1]"代表第1位为数字1,"[358]"代表第二位可以为3、5、8中的一个,"\\d{9}"代表后面是可以是0~9的数字,有9位。 if (TextUtils.isEmpty(mobileNums)) return false; else return mobileNums.matches(telRegex); }
”^((13[0-9])|(14[5,7,9])|(15[^4])|(18[0-9])|(17[0,1,3,5,6,7,8]))\d{8}$”这句话其实很简单:
①130-139这十个前三位已经全部开通,后面8位每一位都是0-9之间的任意数;
②14开头的目前只有145、147、149三位,后面8位每一位都是0-9之间的任意数;
③15开头的除了154以外第三位可以随意取,后面8位每一位都是0-9之间的任意数;
④180-189这十个前三位已经全部开通,后面8位每一位都是0-9之间的任意数;
⑤17开头的目前有170、171、173、175、176、177、178这七位,后面8位每一位都是0-9之间的任意数;
这些正则表达式只是在前端进行判断,实际开发里面这些数据依旧会传给后台,后台会在数据库里去判断这11位号码是不是手机号,我们这样写是为了过滤一些最基本的号码,保证输入的号码位数是11位,还有就是一些看起来就不是手机号的某些11位数。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
