thinkphp not found php module

In the process of using thinkphp for development, sometimes you will encounter the error message "php module not found". This kind of error message may confuse beginners and they don't know where to start to solve the problem. This article will introduce the causes, solutions and preventive measures of this error to help readers easily solve related problems.

1. Cause of the error

When using thinkphp, if the error message "php module not found" appears, it is usually because PHP on the server lacks relevant extensions or dependent libraries. This error message is usually accompanied by a specific PHP module name, such as "pdo_mysql", "gd", "mbstring", etc. These modules are commonly used extensions or dependent libraries in PHP.

2. Solution

1. Install the corresponding php module

For different "php module not found" error prompts, you can install the corresponding php module to solve the problem. Taking the "pdo_mysql" module as an example, you can install it through the following command:

sudo apt-get install php-mysql

2. Modify the php.ini configuration file

In addition to installing the missing php module, you can also install it through Modify the php.ini configuration file to solve the problem. We can find the location of the php.ini file through the following steps:

php --ini

This command will output the location of the php.ini file. Under the Ubuntu system, the default is /etc/php/7.2/cli/php. ini, under CentOS system it is in /etc/php.ini.

After finding the php.ini file, you can modify it according to the following steps:

• To open the php.ini file, you can use the nano or vi command
• in the file Find the part about the corresponding php module, such as "extension=pdo_mysql.so"
• If there is a ";" in front of it, it means it has been commented out, and you need to remove the ";"
• Save the file and restart the php-fpm service

This method is applicable to both the php command line and the web server environment.

3. Modify the php-fpm configuration file

If you are using php-fpm, you can also solve the problem by modifying the php-fpm configuration file. This configuration file is generally located at /etc/php/7.2/fpm/php-fpm.conf or /etc/php-fpm.d/www.conf.

The specific steps are as follows:

• Open the php-fpm.conf file, you can use the nano or vi command
• to find something similar to "php_value[pdo_mysql.default_socket] =/var/lib/mysql/mysql.sock" configuration item, remove the comment character ";", save the file
• Restart the php-fpm service

3. Preventive measures

1. Install necessary PHP extensions

Before deploying the application, first check whether the necessary PHP extensions have been installed, such as commonly used extensions such as pdo_mysql, gd, mbstring, etc. Avoid deployment failures due to missing extensions.

2. Comply with development specifications

During the development process, you should abide by development specifications and try not to use functions and class libraries that may not exist in the system or third-party extensions. Ensure the deployment process is stable and reliable.

3. The development environment and the production environment are consistent

When switching between the development environment and the production environment, you should ensure that the PHP versions and extension libraries of the two environments are consistent to avoid Some extensions are missing due to switching environments.

4. Summary

"php module not found" is one of the common errors in the development process. We can install the missing php module, modify the php.ini configuration file or php-fpm configuration file to solve the problem. In addition, we must also pay attention to preventive measures such as complying with development specifications and ensuring that the development environment and production environment are consistent to ensure smooth application deployment.
