I have been running some basic sites on Bluehost for a few months without any real problems yet. They are Drupal 5.1 and running under PHP 4.4.6.
In anticipation of adding more modules, I would like to bump up the "memory_limit" PHP setting to at least 32, which Bluehost will allow me to do by making changes to the php.ini file located in the root ( public_html ) folder.
My question relates to a comment in the php.ini file ( from Bluehost ) that says:
";;;;;;;;;;;;;;;;;;;;;;;;;;;
; Bluehost Considerations ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;
; If you would like to change the PHP environment for any PHP files
; in your account, make the changes to this file. Then copy this file to
; all directories, including subdirectories, that have PHP files in them.
;
; NOTE: If you do not copy this file to all directories and subdirectories
; with PHP files, your changes here will not affect those files in other
; directories."
In my limited knowledge of how Apache and PHP work, it was my assumption that if I make changes to this "root" php.ini file, it would be applicable to ALL php script execution, unless overridden by the occurrence of another php.ini file in another folder from which a script would be executed.
