Recently, PHP version 8.3 was officially released. This is a major update that brings a more efficient, faster and more convenient programming experience to PHP programmers.
1. Update content
Compared with PHP 8.2, the update of PHP 8.3 version mainly focuses on the following three aspects:
- New syntax features
PHP 8.3 adds some syntax features, such as:
- Variables can use prefix increment and prefix decrement operators in the same statement.
- Added static syntax feature for calling class member properties and methods.
- You can use functions for type declaration.
These new features simplify the code writing process and improve the readability and maintainability of the code.
- Improve existing features
In addition to adding new features, PHP 8.3 also improves some existing features, such as:
- Optimization Improves the internal implementation and operation efficiency of arrays.
- The support for FFI (Foreign Function Interface) is more complete, which improves the efficiency of calling C code and system library functions.
- Processor architecture aware extension support is wider.
These improvements make PHP run more stable and perform more efficiently.
- Strengthened security
In terms of security, PHP 8.3 has taken the following measures:
- Strengthened the encryption of the password hashing mechanism .
- The security of input filtering has been enhanced to avoid security risks such as injection attacks.
- Enhance the security of Cookie and Session.
These security improvements can make PHP 8.3 more secure and reliable, especially in scenarios where sensitive data is processed.
2. Advantages
Compared with the previous version, the new version of PHP 8.3 brings many advantages, mainly including the following aspects:
- Performance Improvement
PHP 8.3 has made many performance optimizations. In actual scenarios, the performance has been improved by about 10%-20% compared to the PHP 8.2 version. This is suitable for users who need to process large amounts of data or high It is very friendly to the concurrent request system.
- Code readability
New syntax features and optimization of existing features make PHP 8.3 code easier to read and write, helping programmers Understand the code better and improve the maintainability and readability of the code.
- Higher security
Enhancements to password hashing, input filtering, cookies, etc. make PHP 8.3 more secure and reliable for processing Very suitable for scenarios with sensitive data.
3. Application scenarios
The new features and improvements of PHP 8.3 make it more suitable for processing the following scenarios:
- Large data volume processing
The performance optimization of PHP 8.3 makes it more suitable for scenarios where large amounts of data are processed, such as querying and processing large databases.
- High concurrent requests
In the scenario of high concurrent requests, PHP 8.3 has a better performance experience than the previous version and can support more requests volume, providing faster response speed.
- Scenarios with high security requirements
PHP 8.3 has enhanced password hashing, input filtering, cookies, etc., making it more suitable for handling high security requirements scenarios, such as processing sensitive data such as online banking and online payments.
4. Conclusion
The release of PHP 8.3 has brought a more efficient, faster and more convenient programming experience to PHP programmers, especially for large data processing and high concurrent requests. It also provides better support for scenarios with high security requirements. The update of this version will definitely promote PHP to gain more advantages in future development.

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。

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。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在PHP中,可以利用implode()函数的第一个参数来设置没有分隔符,该函数的第一个参数用于规定数组元素之间放置的内容,默认是空字符串,也可将第一个参数设置为空,语法为“implode(数组)”或者“implode("",数组)”。

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。

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),
