What is the purpose of the Php.ini file?

The php.ini file is a text file used to configure a whole range of PHP language parameters: compilation options, extensions, versions, server information, PHP environment, system information, paths, general and local configuration values, HTTP headers and the PHP licence.

The php.ini file can be used, for example, to view and modify :

max_input_vars memory_limit max_execution_time upload_max_filesize post_max_size

You can view all your PHP parameters by displaying a phpinfo in a web browser.

How do I modify the php.ini file on my VPS server via SSH?

1) Connect to your dedicated VPS server using SSH

2) Edit your php.ini file using the following command :

If you are using mod_php and therefore php.5.4 :

nano /etc/php5/apache2/php.ini

If you are using fast-CGI and php 5.3 :

nano /opt/phpfcgi-5.3.22/lib/php.ini

If you are using php-fpm :

with version php 5.3

 nano /opt/php-5.3.22/lib/php.ini

with php 5.4 :

 nano /opt/php-5.4.41/lib/php.ini 

with version php 5.5 :

 nano /opt/php-5.5.7/lib/php.ini 

with version php 5.6 :

 nano /opt/php5/fpm/php.ini 

with version php 7.0.15 :

 nano /opt/php-7.0.15/lib/php.ini 

with version php 7.1.1 :

 nano /opt/php-7.1.1/lib/php.ini 

For problems related to the SUHOSIN patch, the file is as follows:

Example of SUHOSIN errors:

Warning, your hosting provider is using the suhosin patch for PHP, which limit the maximum number of fields to post in a form: 1000 for suhosin.post.max_vars. 1000 for suhosin.request.max_vars. Please ask your hosting provider to increase the suhosin post and request limit to 4252 at least. or edit the translation file manually.

3) Modify the file as required and save it.

ctrl+x

4) Restart the Apache web server to take account of the changes made.

/etc/init.d/apache2 restart /etc/init.d/php5-fpm restart (for those using php-fpm and version 5.6) /etc/init.d/php-5.3.22 restart (for those using php-fpm and version 5.3) /etc/init.d/php-5.4.41 restart (for those using php-fpm and version 5.4) /etc/init.d/php-5.5.7 restart (for those using php-fpm and version 5.5) /etc/init.d/php-7.0.1 restart (for those using php-fpm and version 7.0.1)

If the restart was successful, you will get the following message;

Restarting web server: apache2 ... waiting .

If you get a message with the keyword ERROR, you have a problem. The following file should tell you what the problem is:

tail -f /var/log/apache2/error.log

I want a technician to modify the php.ini file on my VPS server. How do I do this?

LWS offers managed services for people who don't want to connect directly via SSH (a handling error can happen very quickly).

There are two solutions: either you have subscribed to a support option: this intervention is included in your package --> simply open an incident ticket with the technical department to indicate which directive needs to be changed.

Or, you can set up a one-off facilities management service: a technician will call you back within the hour and carry out the work with you. The technician will take the time to answer your questions and explain the changes made.
