1、安装php:将下载的php压缩文件解压,文件夹改名为php复制到c盘根目录下。
2、 打开刚才解压的PHP目录,你会发现有一个叫做"php.ini-dist"的文件,这就是PHP的配置文件了,你需要把它改名成"php.ini",然后复制到系统目录winnt下。
3、 PHP安装目录下的"php4ts.dll"必须要复制到windows系统的system32目录下
4、dlls和extensions目录里的所有文件拷到system32 里
修改php.ini其中有必要注意的是
270行error_reporting = E_ALL & ~E_NOTICE
277行display_errors = On
另:365行register_globals 默认 Off,改成on的意思是打开全局变量,以后编程方便。
; cgi.force_redirect = 1改成 cgi.force_redirect = 0这样做是强迫不运行在cgi模式下
Apache2安装
首先停止你的iis或pws服务。
1 运行你下载的Apache2安装文件,安装Apache,安装过程中会提示你输入主机名,管理员信箱等信箱,这些信息在你安装完以后是可以修改的,所以可以放心的输入。
(*为了以后操作方便起见,强烈建议将此处的安装路径用"Change"改变到"X:"下(注X为你的硬盘盘符)或者符合8.3文件名格式的其他名称,以后每次输入Apache安装路径时,都不必为其添加引号。系统安装成功后将自动在此建立一个名为"Apache2"的目录,也就是说,安装之后的实际Apache系统文件所在路径将为"X:Apache2"目录。*)
安装完后,在apache2confhttpd.conf 下查找ServerAdmin,即可修改管理员信箱,(199行附近);213行则是ServerName 我改为localhost
以后我都是把程序放在了apache2的htdocs下的子目录zimulu,用http://localhost:81/zimulu/xxx.php 测试。
2 编辑apache2/conf/httpd.conf
120行Listen 80改为81端口,这是因为当你的win2k重起后,iis将会重占80端口,为避免冲突,所以apache使用81端口。
下面的134-170行左右为加载模块的部分。在这部分下面的加上两句:
LoadModule php4_module c:/php/sapi/php4apache2.dll
//注释:如果你的php目录不是C:/php,请按实际来写。
AddType application/x-httpd-php .php .php3 .php4
(这一句有人说也可以加到768行左右的AddType application/x-tar .tgz之后,不过我有一次这么作了以后没弄成)意思是:加载php4模块, 其中第2句如果仅仅是AddType application/x-httpd-php .php则只能解析php扩展名的文件,php3扩展名的程序解析不了。
注意:我们一般是模块化运行php,所以仅仅这样即可,有的文章说如此添加:
ScriptAlias /php/ "c:/php/"
AddType application/x-httpd-php .php
Action application/x-httpd-php "/php/php.exe"
或者
LoadModule php4_module c:/php/sapi/php4apache2.dll
AddType application/x-httpd-php .php4
ScriptAlias /php4/ "c:/php/"
Action application/x-httpd-php4 "/php4/php.exe"
AddType application/x-httpd-php4 .php
其实是以cgi方式运行php,没有那个必要。
找到DirectoryIndex * 这行,可以这样修改,添加默认的文件名:
DirectoryIndex index.php default.php index.htm index.html default.htm default.html
否则不能自动识别index.php。
使之支持中文
最好的解决办法是:修改了Apache中conf/httpd.conf文件,查找 AddDefaultCharset ISO-8859-1
并且改成
#AddDefaultCharset ISO-8859-1
AddDefaultCharset GB2312

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
