按照教程用Homebrew安装好了PHP,但是怎么打开PHP呢?
可能这个问题太小白了,我没有Google到解决方法。。。初学者,安装好PHP、MySQL就已经蒙圈了,求各位大大原谅我提这么蠢的问题。感谢感谢!
谢谢大家的耐心!没有一个人说我蠢,人间自有真情在哈哈~!

我大概能理解你的意思,PHP不是应用程序,没法打开(我感觉我这句话说得有一点问题…不过没关系了…反正别想“打开”php就是啦~),homebrew安装完成PHP以后,你就可以进行PHP的开发了,推荐使用IDE来进行之后的工作,可以省略很多步骤。IDE推荐使用jetbrain家的PHPstorm。
如果不用IDE的话,桌面去新建一个文件夹(phptest),然后用文本编辑器(推荐使用sublime)写一个简单的php文件,比如index.php,里面写一个然后输入命令:php -S localhost:8888(端口可以自己随便填)
然后可以看到这样:
然后浏览器里访问:localhost:8888就可以看到本机安装的PHP的信息了。
再举几个例子,比如你想循环输出hello world一百遍。把index里的内容改成这样:
command+s保存,然后刷新浏览器localhost:8888。就可以看到效果了。
至于IDE就比较简单了,就不多说了。
MAC下强烈建议MAMP套件。很方便好用。][2]
mac 下自带了 apache 和 php , 控制 apache 的程序是 apachectl , 终端下输入 apachectl start 即可启动 apache 服务器。
建议用macports或brew这种管理工具 命令行大法好
phpStorm,集成开发环境(就是IDE啦),类似xcode.
这个用来编写项目代码的,但是运行的话,需要把你的项目放到web目录下面,用浏览器去访问目录地址
我也刚会搞。。。。。。 (%>_

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
