wkhtmltopdf is working via terminal, but not via PHP
If wkhtmltopdf
is working fine when executed via the terminal but not when called from PHP, there are a few common issues you can investigate:
Path Configuration: When running
wkhtmltopdf
from the terminal, the executable may be accessible due to the system's environment variables and PATH settings. However, PHP may not have the same environment variables configured. You can try providing the full path to thewkhtmltopdf
executable in your PHP code to ensure it can be found.Permissions: Check the permissions on the
wkhtmltopdf
executable and the directories it accesses. Ensure that the PHP process running your script has appropriate read and execute permissions for the necessary files and folders.User/Group Differences: The terminal and PHP may run under different users or groups, resulting in different permissions and access levels. Confirm that the PHP process has the necessary permissions to execute
wkhtmltopdf
and access any required files or resources.Environment Variables: If
wkhtmltopdf
relies on specific environment variables to function correctly, make sure those variables are set when running PHP. You can set environment variables within your PHP script using theputenv()
function or by modifying the server's PHP configuration.Output File Destination: Check the destination directory where the generated PDF file is being saved. Ensure that the PHP process has write permissions to that directory.
Error Handling: Wrap the
wkhtmltopdf
command within PHP in a try-catch block and check for any exceptions or error messages that are being thrown. This can provide more specific information about what might be going wrong.
By investigating these points, you should be able to identify and address the issue causing wkhtmltopdf
to not work when called from PHP.
