To use php5 (at least with my webhost) you need to copy everything you have in .htaccess into a file called php.ini except anywhere it says php_value in the htaccess, you just erase those words.

Here's an example of an .htaccess file:

Code:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

<IfModule mod_gzip.c>
mod_gzip_on No
</IfModule>


php_value upload_max_filesize 100M 
php_value post_max_size 100M 
php_value output_buffering on 
php_value max_execution_time 1000 
php_value max_input_time 1000 
php_value session.gc_maxlifetime 14400 

<IfModule mod_security.c>
SecFilterEngine Off
Here's the same thing, but in php.ini (for php5)

Code:
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

<IfModule mod_gzip.c>
mod_gzip_on No
</IfModule>


upload_max_filesize 100M 
post_max_size 100M 
output_buffering on 
max_execution_time 1000 
max_input_time 1000 
session.gc_maxlifetime 14400 

<IfModule mod_security.c>
SecFilterEngine Off
You might have to add "register_ globals off" or "register_globals on" to it (I had to do that with one script to be able to log in---not vshare but something else). You can't use the new features of vShare without PHP5.
