How to Display PHP Configuration for Your Vtiger CRM

Start with your hosting control panel

Sign in to your hosting panel, select the domain or subdomain used by Vtiger, and open its PHP settings or PHP version selector. Menu names vary by provider. Check the selected PHP branch without changing it.

If the panel shows only a branch such as 8.2, ask the provider for the complete installed PHP package version when checking security updates. For detailed values such as memory limits and loaded extensions, use the browser method below.

Display the PHP configuration in your browser

1Find your Vtiger installation folder

Open your hosting file manager or connect using SFTP. Locate the folder containing Vtiger's index.php and config.inc.php. Do not edit either file. Use the CRM directory, not the WordPress directory or another website on the server.

2Create a temporary PHP information file

After restricting access to the diagnostic page, create crm-php-info.php in that folder. Save it as plain text with the following content:

<?php
header('Cache-Control: no-store');
phpinfo(INFO_GENERAL | INFO_CONFIGURATION | INFO_MODULES);

This limits the report to general information, configuration and modules. It omits the dedicated environment and request variable sections, but the remaining report still contains sensitive server details. A hard to guess filename alone is not access protection.

3Open the file using your CRM address

Open the address in your browser through the protected access you configured. The page reports the PHP runtime executing that file on the CRM domain. Per script or application overrides can still make some values differ inside Vtiger.

4Record the relevant values and remove the file

Note only the values needed for your investigation, then delete crm-php-info.php. Confirm that the report is no longer served. Do not publish the report or share a complete screenshot containing internal paths or other private details.

Which PHP settings should you check for Vtiger?

Use your browser's search function to find these entries in the report. Compare the values with our Vtiger system requirements and the requirements of your installed extensions.

Need only the PHP version? You can use this smaller temporary file instead of the full report. Apply the same access restrictions and deletion step:

<?php
header('Content-Type: text/plain; charset=UTF-8');
header('Cache-Control: no-store');
echo phpversion();

Check PHP through SSH and compare it with Cron

If you have SSH access, run these commands separately:

php -v
php --ini
php -m

php -v displays the command line version, php --ini lists its configuration files, and php -m lists its loaded modules.

What if the PHP information page does not work?

Check first, then plan configuration changes

Once you know the active environment, follow our guide to changing PHP settings for Vtiger. Back up configuration before making changes and test the CRM functions involved.

Do not switch to a newer PHP branch without checking Vtiger, extension and custom code compatibility. For older installations, our Vtiger upgrade service can help plan a compatible upgrade path. For the recent security issues, read our PHP security update guide for Vtiger CRM.
