PHP PDO MySQL source code compilation and installation guide

PHP is a commonly used server-side scripting language, while MySQL is a popular relational database management system. PHP PDO is part of PHP Data Objects, which provides a lightweight, consistent interface to access various databases. When compiling and installing PHP, you can interact with the MySQL database by turning on PDO MySQL support. This article will provide readers with a full guide to enabling PDO MySQL support in PHP compilation and installation, with specific code examples.

Step One: Preparation

Before compiling and installing, you first need to ensure that the necessary tools and dependent libraries have been installed in the system. Before installing PHP, you need to ensure that the following software packages have been installed in the system:

• gcc compiler
• make tool
• automake
• autoconf
• libxml2
• libxml2-devel
• zlib
• zlib-devel
• openssl
• openssl-devel
• libcurl
• libcurl-devel

You can install these software packages through the system's default package management tool. For example, you can use the apt-get command in Debian/Ubuntu systems. , you can use the yum command in CentOS systems.

Step 2: Download PHP source code

Before compiling and installing PHP, you need to download the latest PHP source code package from the PHP official website (https://www.php.net/downloads). Select the appropriate version and download it locally through the wget command or in the browser.

$ wget https://www.php.net/distributions/php-7.4.0.tar.gz

Step 3: Decompress the source code package and configure compilation options

Decompress the downloaded PHP source code package, enter the decompressed directory, and execute the configure command to configure compilation options. During configuration, you need to enable PDO MySQL support and specify the MySQL installation path.

$ tar -zxvf php-7.4.0.tar.gz
$ cd php-7.4.0
$ ./configure --with-pdo-mysql --with-mysql=/path/to/mysql

Step 4: Compile and install PHP

After the configuration is completed, execute the make command to compile the PHP source code, and execute the make install command to install PHP into the system.

$ make
$ make install

Step 5: Verify the installation result

After the compilation and installation are completed, you can create a simple PHP file and check whether PHP has enabled PDO MySQL support through the phpinfo function. Create a file named info.php and enter the following content:

<?php
phpinfo();
?>

After saving the file, place it in the root directory of the website, access the file through the browser, and check whether there is PDO MySQL related information in the phpinfo page .

Conclusion

Through the above steps, we can successfully enable PDO MySQL support during the PHP compilation and installation process. By turning on PDO MySQL support, we can easily connect and operate the MySQL database in PHP to achieve more powerful database interaction functions. I hope this article is helpful to readers, and I wish you smooth compilation and installation!
