With the continuous development and popularization of Internet technology, Web development has become an indispensable part of people's work and life. As a server-side scripting language, PHP is widely used in the field of web development and is used by many websites. However, in actual development, sometimes we encounter situations where the PHP file in the server cannot run normally. At this time, we need to carefully troubleshoot the problem and solve it.
1. Modify the PHP.ini file
When solving the problem that the PHP file cannot run on the server, you first need to check whether the PHP configuration file is normal. The PHP configuration file is configured by the PHP.ini file, so if there is a problem with the PHP.ini file, the PHP file may not run properly. Here are some possible reasons for problems with the PHP.ini file:
The methods to solve these problems are as follows:
php --ini
Find the PHP.ini file based on the output results, and check whether the file path is correct.
max_execution_time = 60 memory_limit = 128M post_max_size = 50M upload_max_filesize = 50M
After modification, save the file and restart the server.
ls -l /path/to/php.ini
Confirm whether you have read and write permissions. If not, you can use the following command to change the file permissions:
chmod 644 /path/to/php.ini
2. Check PHP program syntax
When a PHP file does not run properly, it may be because there are syntax errors in it. You can check whether the syntax of the PHP file is correct by the following method:
php -l /path/to/file.php
If an error message similar to "Errors parsing /path/to/file.php" is output, it means that there is a syntax error in the file and needs to be modified. Rerun.
3. Check the Web server configuration
If the PHP.ini file and PHP program syntax are correct, but the PHP file still cannot run normally, you can consider checking whether the Web server configuration is correct. For different web servers, the configuration method may be different. Here is the Apache server as an example:
apache2ctl -M | grep php
If there is no output, it means that the PHP module is not enabled. You can enable the module using the following command:
sudo a2enmod php7.2
Then restart the Apache server.
<FilesMatch ".php$"> SetHandler application/x-httpd-php </FilesMatch>
If not, you need to manually add it and restart the Apache server.
ls -l /usr/bin/php
Confirm whether you have execution permissions. If not, you can use the following command to change the permissions:
chmod +x /usr/bin/php
4. Summary
Server The PHP file in the file cannot run normally, which may cause inconvenience and impact on web development, so we need to carefully troubleshoot the problem and solve it in time. This article introduces some methods to troubleshoot the problem that PHP files cannot run on the server, including modifying the PHP.ini file, checking PHP program syntax, checking Web server configuration, etc. We hope that these methods can help readers efficiently solve the problem of PHP files that cannot run.
