Linux上安装PHP的问题
在虚拟机上安装PHP(测试成功通过,问题已经解决) (1)首先把php-5.2.17.tar.gz挂载到操作系统上 mount /mnt/cdrom(我的做法是然后复制到/home/soft目录下,这里专门放置我的软件包,读者可以不需要这样做) (2)然后解压 tar -zxvfphp-5.2.17.tar.gz ,
在虚拟机上安装PHP(测试成功通过,问题已经解决)
(1)首先把php-5.2.17.tar.gz挂载到操作系统上 mount /mnt/cdrom(我的做法是然后复制到/home/soft目录下,这里专门放置我的软件包,读者可以不需要这样做)
(2)然后解压 tar -zxvf php-5.2.17.tar.gz ,当前目录出现php-5.2.17文件,进入php-5.2.17文件中cd php-5.2.17
(3)然后准备安装./configure --prefix=/usr/local/php
--with-apxs2=/usr/local/apache/bin/apxs
--with-mysql=/usr/local/mysql
(4)当执行第三步的代码的时候出现configure: error: libxml2 version 2.6.11 or greater required.这样的问题,这样就不能make以及make install操作了。首先分析问题,看到刚才报错的提示,发现时操作系统自带的libxml2的版本过低。这个时候需要在本操作系统上查看是否安装过libxml.
(5)rpm -qa |grep libxml,发现本操作系统确实安装了libxml的软件,但是版本过低,此时我在www.xmlsoft.org网站中下载更高的版本程序包(libxml2-2.7.2。tar.gz)准备进行安装
(6)首先是卸载过低版本的libxml2。rpm -e libxml --nodeps(强制删除)
(7)卸载完之后接下来安装新版本的libxml2-2.7.2.步骤:挂载-》解压,解压后进入到libxml2-2.7.2目录中然后执行./configure --prefix=/usr/local/libxml命令准备安装-》make->make install 这样就安装完心版本的libxml2-2.7.2
(8)安装完之后返回第三步重新开始安装PHP
./configure --prefix=/usr/local/php
--with-apxs2=/usr/local/apache/bin/apxs
--with-mysql=/usr/local/mysql
(9)这时候还是出现configure: error: libxml2 version 2.6.11 or greater required.这样的问题,经过分析后发现在PHP的安装过程中没有指定libxml2所在的路径,所以附带参数-
./configure --prefix=/usr/local/php
--with-apxs2=/usr/local/apache/bin/apxs
--with-mysql=/usr/local/mysql
--with-libxml-dir=/usr/local/libxml。
(10)这时候执行成功,然后执行make,最后执行make install
(11)当我第二天启动系统执行startx进入操作界面的时候又出现新的一个问题
error while loading shared libraries: libxml2.so.2:cannot open shared object file: No such file or directory这样的问题。首先经过分析之后找到原因,是因为昨天我安装了libxml2的时候我指定它一个新的安装目录,系统找不到libxml2.so.2
(12)我进入/usr/local/libxml/lib中确实是发有libxml2.so.2。然后我经过分析之后就在/etc/ld.so.conf中加入/usr/local/libxml/lib这一行,保存之后,再运行:/sbin/ldconfig –v更新一下配置即可。
(13)经过以上问题的解决,总体把PHP安装完成,接下来就需要把php,mysql.apache。配置好并运行起来,这样LAMP(Linux+Apache+MySQL+PHP)环境搭建好了。

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.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

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 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.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

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.
