Linux source code compilation of php5.4 and above comes with the configure parameters and dependency packages of php-fpm
I often need to compile and install PHP myself in the Linux environment. There are many configure parameters. Sometimes I have to recompile PHP when I use it without paying attention, so the commonly used configure commands are organized as follows.
The first step is to install the dependent package:
yum -y install gcc make gd-devel libjpeg-devel libpng-devel libxml2-devel bzip2-devel libcurl-devel libaio
In fact, you may also need to install the mcrypt extension (typical error: phpmyadmin reports an error and cannot load the mcrypt extension).
To install the mcrypt extension, you can use the command:
yum install libmcrypt-devel
Then use the command:
yum install php-mcrypt
The mcrypt extension is successfully installed.
Second step, install php:
cd /tmp wget http://cn2.php.net/get/php-5.5.10.tar.gz/from/cn2.php.net/mirror tar -zxvf mirror cd ./php-5.5.10
Then execute the command:
./configure \ --prefix=/usr/local/php5 \ --with-config-file-path=/usr/local/php5/etc \ --with-bz2 \ --with-curl \ --enable-ftp \ --enable-sockets \ --disable-ipv6 \ --with-gd \ --with-jpeg-dir=/usr/local \ --with-png-dir=/usr/local \ --with-freetype-dir=/usr/local \ --enable-gd-native-ttf \ --with-iconv-dir=/usr/local \ --enable-mbstring \ --enable-calendar \ --with-gettext \ --with-libxml-dir=/usr/local \ --with-zlib \ --with-pdo-mysql=mysqlnd \ --with-mysqli=mysqlnd \ --with-mysql=mysqlnd \ --enable-dom \ --enable-xml \ --with-libdir=lib64 \ --enable-pdo \ --enable-fpm \ --enable-mcrypt
The compilation process may report the following error:
checking for known struct flock definition… configure: error: Don’t know how to define struct flock on this system, set –enable-opcache=no
The solution is:
yum groupinstall "Development tools"
Finally execute the commands separately:
make make install
The above introduces the configure parameters and dependency packages of php-fpm that come with Linux source code compilation of php5.4 and above, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
