PHP获取指定时间段之间的 年,月,天,时,分,秒
需求:前端传俩个标准的 时间格式过来,格式像2009-05-12 12:12:30,然后根据需要返回这个时间段的不同单位的表示
对于时间格式的校验我这里代码没贴出来,所以用的时候自己考虑加上
Class Utils { /** * format MySQL DateTime (YYYY-MM-DD hh:mm:ss) 把mysql中查找出来的数据格式转换成时间秒数 * @param string $datetime */ public function fmDatetime($datetime) { $year = substr($datetime,0,4); $month = substr($datetime,5,2); $day = substr($datetime,8,2); $hour = substr($datetime,11,2); $min = substr($datetime,14,2); $sec = substr($datetime,17,2); return mktime($hour,$min,$sec,$month,$day,0+$year); } /** * * 根据俩个时间获取俩个时间的 包含的 年,月数,天数,小时,分钟,秒 * @param String $start * @param String $end * @return ArrayObject */ private function diffDateTime($DateStart,$DateEnd){ $rs = array(); $sYear = substr($DateStart,0,4); $eYear = substr($DateEnd,0,4); $sMonth = substr($DateStart,5,2); $eMonth = substr($DateEnd,5,2); $sDay = substr($DateStart,8,2); $eDay = substr($DateEnd,8,2); $startTime = $this->fmDatetime($DateStart); $endTime = $this->fmDatetime($DateEnd); $dis = $endTime-$startTime;//得到俩个时间的秒数 $d = ceil($dis/(24*60*60));//得到天数 $rs['day'] = $d;//天数 $rs['hour'] = ceil($dis/(60*60));//小时 $rs['minute'] = ceil($dis/60);//分钟 $rs['second'] = $dis;//秒数 $rs['week'] = ceil($d/7);//周 $tem = ($eYear-$sYear)*12;//月份 $tem1 = $eYear-$sYear;//年 if($eMonth-$sMonth<0){//月份相减为负 $tem +=($eMonth-$sMonth); }else if($eMonth==$sMonth){//月份相同 if($eDay-$sDay>=0){ $tem ++; $tem1++; } }else if($eMonth-$sMonth>0){//月份相减正负 $tem1++; if($eDay-$sDay>=0){//且日期相减为正数 $tem +=($eMonth-$sMonth)+1; }else{ $tem +=($eMonth-$sMonth); } } $rs['month'] = $tem; $rs['year'] = $tem1; return $rs; } }
一年多一天,返回的是2年,一个月多一天返回的是2个月,以此推......项目需要,才做此出来,开始我也到网上找这样的例子,但大家都是把年就按365天来算,月就按30天来算,这样算出来的结果肯定是没用的,年有可能是366天,月有可能是31,29,28都有可能

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.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
