<?php echo "今天:".date("Y-m-d")."<br>"; echo "昨天:".date("Y-m-d",strtotime("-1 day")), "<br>"; echo "明天:".date("Y-m-d",strtotime("+1 day")). "<br>"; echo "一周后:".date("Y-m-d",strtotime("+1 week")). "<br>"; echo "一周零两天四小时两秒后:".date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")). "<br>"; echo "下个星期四:".date("Y-m-d",strtotime("next Thursday")).

strtotime()函数的作用是将日期时间描述解析为 Unix 时间戳 int strtotime ( string time [, int now] ) PHP星期几获取代码: date("l"); //data就可以获取英文的星期比如Sunday date("w"); //这个可以获取数字星期比如123,注意0是星期日 获取中文星期可以这样 $weekarray=array("日","一","二","三","四","五","六"); echo "星期".$weekarray[date("w")]; 获取指定日期是: $weekarray=array("日","一","二","三","四","五","六"); echo "星期".$weekarray[date("w","2011-11-11")]; 因为date函数非常强大,他完全可以胜任一切这样的工作我附个手册里的表吧 a - "am" 或是 "pm" A - "AM" 或是 "PM" d - 几日,二位数字,若不足二位则前面补零; 如: "01" 至 "31" D - 星期几,三个英文字母; 如: "Fri" F - 月份,英文全名; 如: "January" h - 12 小时制的小时; 如: "01" 至 "12" H - 24 小时制的小时; 如: "00" 至 "23" g - 12 小时制的小时,不足二位不补零; 如: "1" 至 12" G - 24 小时制的小时,不足二位不补零; 如: "0" 至 "23" i - 分钟; 如: "00" 至 "59" j - 几日,二位数字,若不足二位不补零; 如: "1" 至 "31" l - 星期几,英文全名; 如: "Friday" m - 月份,二位数字,若不足二位则在前面补零; 如: "01" 至 "12" n - 月份,二位数字,若不足二位则不补零; 如: "1" 至 "12" M - 月份,三个英文字母; 如: "Jan" s - 秒; 如: "00" 至 "59" S - 字尾加英文序数,二个英文字母; 如: "th","nd" t - 指定月份的天数; 如: "28" 至 "31" U - 总秒数 w - 数字型的星期几,如: "0" (星期日) 至 "6" (星期六) Y - 年,四位数字; 如: "1999" y - 年,二位数字; 如: "99" z - 一年中的第几天; 如: "0" 至 "365"
The above introduces PHP to get today, yesterday, and tomorrow's date, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

MinGW - Minimalist GNU for Windows
This project is in the process of being migrated to osdn.net/projects/mingw, you can continue to follow us there. MinGW: A native Windows port of the GNU Compiler Collection (GCC), freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All MinGW software can run on 64-bit Windows platforms.

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.
