[Chameleon] PHP5 and Chameleon

[Delfos, Jacob]

Hi Bart,

Thanks for giving those instructions. I'll try it out soon.
I did some testing with DLL dependencies, and found that many DLL's have to
be in the system directory. Even if they are in your PATH, it is not
sufficient. This is quite annoying, because I was trying to do things the
'clean' way, to avoid conflicts, by having my DLL's sorted in separate
directories.

Regards,

Jacob

Hi Jacob,

I think the difference between php.exe and php-cgi.exe is that php.exe is
supposed to be used from the command-line only. It used to be one
executable, but I think they separated the two. See also install.txt:

   |-php-cgi.exe          -- CGI executable
   |
   |-php-win.exe          -- executes scripts without an opened command
prompt
   |
   |-php.exe              -- CLI executable - ONLY for command line
scripting

I did not get any error messages with the ROI sample, the only problem I
had was with the sample application finding chameleon.php.

I changed my include_path in php.ini:

include_path = ".;/ms4w/apps/chameleon/htdocs"

And used in the phtml file:

include( "chameleon.php" );

For the whole module thing I had to do the following:

For PHP4 (with PHP5 this is not necessary because they changed the
directory structures):
copy everything from dlls and sapi to the php root directory.

The following config in httpd.conf:

##
## PHP 4 Module config
##
#AddType application/x-httpd-php .php4 .php3 .phtml .php
#LoadModule php4_module "C:/ms4w/Apache/php/php4apache2.dll"
#PHPIniDir "/ms4w/Apache/php/"

##
## PHP 5 Module config
##
AddType application/x-httpd-php .php4 .php3 .phtml .php
LoadModule php5_module "C:/ms4w/Apache/php5/php5apache2.dll"
PHPIniDir "/ms4w/Apache/php5/"

I did move some of the dll's mapscript depends on, into the system32
folder, but I don't know if this is necessary. I guess not, but I was just
lazy ...

Best regards,
Bart
