How can conflicting or multiple php.ini and .htaccess files impact the PHP configuration and execution on a server, and what steps can be taken to resolve such conflicts?

Conflicting or multiple php.ini and .htaccess files can lead to inconsistent PHP configurations and execution on a server. To resolve such conflicts, it is important to ensure that there is only one php.ini file that is being used and that the settings in the .htaccess file do not override those in the php.ini file.

# To ensure only one php.ini file is being used, specify the path to the desired php.ini file in the .htaccess file
# Add the following line to the .htaccess file
# For example, if the php.ini file is located in the root directory:
SetEnv PHPRC /path/to/php.ini
