PHP中使用mktime获取时间戳的一个黑色幽默分析_php技巧
下面这段代码是网上大多数人给出的时间戳现实,这个一看便知只能说是取得当前日期,而不能算是时间戳,不用多解释了吧!
$now = mktime(0,0,0,date("m"),date("d"),date("Y"));
echo "now is ".date("Y/m/d", $now);
显示结果:
now is 2012/05/30
显然这不是我想要的结果。
于是,按照旧有的思维,我想当然的改造成下面这个形式:
$now = mktime(date("h"),date("M"),date("s"),date("m"),date("d"),date("Y"));
echo "now is ".date("Y/M/d h:i:s", $now);
注意红色的部分,通常如果月份用m,那么分钟就应该是M。或者前者用M,后者用m。
显示结果:
Warning: mktime() expects parameter 2 to be long, string given in D:\usr\webroot\testPHP\index.php on line 46
now is 1970/01/01 08:Jan:00
看来主观臆断是不可取的,PHP的语法和其他的语言还是有些区别的。
不卖关子了,还是直接给大家正确的答案
$now = mktime(date("h"),date("i"),date("s"),date("m"),date("d"),date("Y"));
echo "now is ".date("Y/m/d h:i:s", $now);
哈哈~是“i”而不是什么m或者M,这里给出大家这个示例只是想让PHP的初学少走一些弯路。
至于M是什么意思,大家自己做一下就明白了...嘿嘿!!!
显示结果:
now is 2012/05/30 04:54:25
网络上互相复制文章的人太多,没有多少人去深究这个,让如我一样的PHP初学者无所适从。大家拷贝复制之前是不是多动动手自己实现一下在写出了,对自己是个提高,对读者也是一直负责的态度。

Golang time conversion: How to convert timestamp to string In Golang, time operation is one of the very common operations. Sometimes we need to convert the timestamp into a string for easy display or storage. This article will introduce how to use Golang to convert timestamps to strings and provide specific code examples. 1. Conversion of timestamps and strings In Golang, timestamps are usually expressed in the form of integer numbers, which represent the number of seconds from January 1, 1970 to the current time. The string is

In Go, you can use regular expressions to match timestamps: compile a regular expression string, such as the one used to match ISO8601 timestamps: ^\d{4}-\d{2}-\d{2}T \d{2}:\d{2}:\d{2}(\.\d+)?(Z|[+-][0-9]{2}:[0-9]{2})$ . Use the regexp.MatchString function to check if a string matches a regular expression.

Change Date Format in Excel Using Number Format The easiest way to remove time from a date in Excel is to change the number format. This does not remove the time from the timestamp - it just prevents it from displaying in your cell. If you use these cells in calculations, the time and date are still included. To change the date format in Excel using number format: Open your Excel spreadsheet. Select the cell containing your timestamp. In the main menu, select the down arrow at the end of the number format box. Choose a date format. After changing the format, the time will stop appearing in your cells. If you click on one of the cells, the time format is still visible in the formula bar. Use cell formatting

Java document interpretation: Usage analysis of the currentTimeMillis() method of the System class, specific code examples are required. In Java programming, the System class is a very important class, which encapsulates some properties and operations related to the system. Among them, the currentTimeMillis method is a very commonly used method in the System class. This article will explain the method in detail and provide code examples. 1. Overview of currentTimeMillis method

Golang Programming Tool: Best Practices for Timestamp Obtaining Introduction: In software development, timestamp is a very common concept. It is a numeric value that identifies the occurrence of a specific event, usually representing the number of milliseconds or nanoseconds since some reference point in time. In Golang, processing timestamps is very simple and efficient. This article will introduce the best practices for obtaining timestamps in Golang and provide specific code examples. Text: Get the current timestamp In Golang, getting the current timestamp is very simple. we can

Timestamp handling in PHP: How to format a timestamp into a localized date time using the strftime function When developing PHP applications, we often need to deal with dates and times. PHP provides powerful date and time processing functions, among which the strftime function allows us to format timestamps into localized date and time. The strftime function has the following syntax: strftime(string$format[,int$timestamp=ti

Timestamp in PHP is an integer form representing time, usually the number of seconds that have passed since the first year of Unix (January 1, 1970 00:00:00 GMT). In programming, we often need to convert timestamps into other forms of integers. Here we will introduce how to convert PHP timestamps into integers, as well as specific code examples. In PHP, we can use the strtotime() function to convert the time string to a timestamp and then use date
