PHP基础之Win7下PHP开发环境的搭建
今天重做了一次win7系统,所有的环境重新配置
?
步骤如下:
?
一、下载apache,版本:httpd-2.2.17-win32-x86-openssl,apache的安装没有什么特别,默认即可
?
二、安装mysql,版本:5.1,同样,默认安装即可
?
三、安装php,版本:php-5.3.5-Win32-VC6-x86,注意:VC9是专门为IIS定制的,VC6 是为了其他WEB服务软件提供的,如 Apache,我下载的是zip包。
?
然后下面就是配置
?
1.找到
On windows: ; extension_dir = "ext"
改成:
; On windows: extension_dir = "D:/php/ext"
?
2.增加一些常用的库扩展,例如mysql,将前面的分好去掉即可
extension=php_curl.dll extension=php_gd2.dll extension=php_mbstring.dll extension=php_mysql.dll extension=php_pdo_mysql.dll extension=php_pdo_odbc.dll extension=php_xmlrpc.dll
?
?3.配置PHP的Session功能
session.save_path = "D:/phpsessiontmp"
?
4.配置PHP的文件上传功能
upload_tmp_dir = "D:/phpfileuploadtmp
?
5.修改date.timezone,否则在执行phpinfo时date部分默认是美国的LA时间
date.timezone = Asia/Shanghai
?
6.使得apache能够载入conf/extra/httpd-vhosts.conf来设置虚拟主机
# Virtual hosts Include conf/extra/httpd-vhosts.conf
?
7.配置虚拟主机conf/extra/httpd-vhosts.conf
<virtualhost localhost:80> DocumentRoot "D:/PHPServer/workspace" ServerName gm.me ErrorLog "logs/dummy-host2.break.local-error.log" CustomLog "logs/dummy-host2.break.local-access.log" common <directory> AllowOverride None Options Indexes Order allow,deny Allow from all </directory> </virtualhost>
?
8.我们应该知道默认Apache服务器执行WEB主程序的目录为Apache2.2/htdocs,所以当你的WEB主程序目录变更时,我们需要修改相应的Apache配置
DocumentRoot "D:/PHPServer/workspace"
?
9.配置apache以支持php
LoadModule php5_module "d:/php/php5apache2_2.dll" PHPIniDir "d:/php" AddType application/x-httpd-php .php .html .htm
?此处注意:如果下载的php版本不对,例如不带线程安全的就会发现在php目录下面没有
php5apache2_2.dll
?
10.具体的index文件先后顺序,由于配置了PHP功能,当然需要index.php优先执行
DirectoryIndex index.php index.html?
?

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
