Chapitre 56. Miscellaneous Questions

Get powered by PHP from: 

I wish to do the following using php scripting techniques:
Accept text through a text box from a user, open an existing jpg file,
place the user's text upon  it and save the composite as a different file.
In order to do this I tried the following php  code.

-------------
<?php 

$img_number = imagecreatefromjpeg ("blue-button.jpg");

$namee="web";
 
Imagettftext($img_number, 30,0,10,33,$black,"ARIAL.TTF",$namee);

$fp=fopen("button.jpg", "w+");

header("Content-type: image/jpeg"); 

imagejpeg($img_number,"button.jpg",100); 

?>

---------------

I also put a jpg file called blue-button.jpg in the same folder where I
put the php file. When I  try to run this php file on your servers I
received the following error.

Error

Warning: ImageTtfText: No TTF support in this PHP build in

I would be grateful to you if you could tell me if this is the reason why
the function is  crashing and how to rectify it, or, alternatively, let me
know of a workaround that will solve  the problem.

I installed PHP without errors (on Xitami), but if I try to run a
php-script i get this error message:

Security Alert! The PHP CGI cannot be accessed directly. 
This PHP CGI binary was compiled with force-cgi-redirect enabled. This
means that a page will only be served up if the REDIRECT_STATUS CGI
variable is set, e.g. via an Apache Action directive.

For more information as to why this behaviour exists, see the manual page
for CGI security.

For more information about changing this behaviour or re-enabling this
webserver, consult the installation file that came with this distribution,
or visit the manual page.

How can I "repair" this bug?

Edit the php.ini file in your windows directory and look for the Directive
it mentions.  Change it to 0 (I think) and restart the server.  Should
work then...

Is anyone doing work on the PHP module to give it the functionality of say
perl_mod or python_mod. I think giving PHP programmers the ability to
write handlers and modules in PHP for Apache would be great.

It seams that this could be added with a little tweaking of the run-time
module.

you can do this by defining a php-script as a handler for special files:

AddHandler xmldoc xml
Action xmldoc /xmlparse.php4

so for every file with .xml ending the client requests, the xmlparse.php4
would get executed and the path to the script is set in $PATH_INFO, so you
can write your own handlers for special file types (okay its not exactly a
mod_xxx but its truly near on that)

I see what your saying, and understand it and how it works. But my question
is since you can't access the the internal apache data table how can you
get values like the uri requested and things available to real modules
from apache. It seems to me that the php script would have no way of
getting the requested file to parse.

Am I wrong here?
