PHP DateTime extension overview
php editor Strawberry introduces you to using PHP DateTime extension to explore time zone and date operations. With the development of time, people's time management has become more and more important. PHP DateTime extension provides us with rich functions to help us better control time. Whether dealing with time zone conversion, date formatting, or date calculation and other operations, the PHP DateTime extension can provide powerful support. Let’s take a deeper look at this extension and explore the mysteries and fun of time.
- Represent dates and times as objects
- Perform date and time operations
- Format date and time
- Convert date and time to different time zone
- Compare dates and times
Use the PHP DateTime extension to manipulate dates and times
Create DateTime object
To use the PHP DateTime extension, you first need to create a DateTime object. You can create a DateTime object using one of the following methods:
- Use the
new DateTime()
function to create the current date and time object - Use
new DateTime("2022-03-08 12:30:00")
function to create a specific date and time object - Use the
new DateTime(1646791800)
function to create a date and time object from a Unix timestamp
Getting and setting date and time
You can use the following methods to get and set the date and time of a DateTime object:
- Use the
getDate()
method to get the date part - Use
getTime()
method to get the time part - Use the
setDate()
method to set the date part - Use the
setTime()
method to set the time part
Format date and time
You can use the following methods to format the date and time of a DateTime object:
- Use the
f<strong class="keylink">ORM</strong>at()
method to format the DateTime object into a string - Use the
setTimestamp()
method to set the timestamp of the DateTime object to the specified timestamp
Convert time zone
You can convert a DateTime object to a different time zone using the following methods:
- Use the
setTimezone()
method to convert the DateTime object to the specified time zone - Use the
getOffset()
method to obtain the time zone offset of the DateTime object - Use the
getDateTime()
method to convert the DateTime object to UTC time
Compare dates and times
You can use the following methods to compare the date and time of two DateTime objects:
- Compare the dates of two DateTime objects using the
, <code>>
,and <code>>=
operators and time - Use the
diff()
method to get the difference between two DateTime objects
Conclusion
ThePHP DateTime extension is a powerful tool for working with dates and times. It provides many useful functions and classes that can help us easily manipulate date and time and perform various date and time related operations.

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。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
