[PHP] exec won't pass arg with spaces

[Raul Millan]

I'm trying to execute /usr/bin/convert passing the image size and the 
file name, the problem is that the file name contains lots of spaces, so 
I try to pass "filename with lots of spaces", and nothing works.

I've read something about safe mode, but I have safe mode disabled; I 
also read something about a bug, but nothing definitive.  Can someone 
point me in the right direction?

Here's is my configuration:

Red Hat Linux 9
php-4.2.2-17.2
httpd-2.0.40-21.3
Sample code:

        exec("$imagemagickPath/convert -geometry " .
        "{$thumbnail_width}x{$thumbnail_height} " .
        "$images_dir/$filename $images_dir/tb_$filename");
where filename could be:
/var/www/html/images/SPIN CoreRT1 to EX-JF1  (cw - kpi - KPI Performance 
Report(Weekly).png

What I'm trying to do is simply create thumbnails of images stored in a 
directory, there are thounsands of images.

I've tried to send the complete strings to a externa script that 
executes convert, but at the moment of exectution the " are removed and 
the scripts fails.

Here is a extract of the /var/log/httpd/error_log

convert: Unable to open file 
(/var/www/html/ivexport/spinkpi_offline/tb_SPIN - Core-Rt2 POS to ATL 
(cw - WAN Link Performance - 3 Daily).png).

I'm not very experienced with PHP, and it's been a coulpe of years since 
I coded.

Any help would be greatly appreciated.

Regards,

Raúl Millán
