Php and ImageMagick in Windows?

[Chuck Anderson]

I am trying to use ImageMagick from a Php script running under Windows XP.

I have installed the latest version of ImageMagick - 6.2.1-7 and even
tried backing up to version 5.5.7 (based on a recommendation I found
during a Google search), but I can not get ImageMagick to work in Php
(using exec or system).

ImageMagick works from a Windows Command prompt -

e.g., convert C:\apache\htdoc s\testing\temp_ .jpg
C:\apache\htdoc s\testing\temp_ .png

but that same command using the system function -

i.e., system("convert C:\apache\htdoc s\testing\temp_ .jpg
C:\apache\htdoc s\testing\temp_ .png", $retval);

always fails with a retval of either 4 or 1. (The retval was 4 until I
rebooted and tried again, and now it is always 1).

I am able to execute other windows commands (e.g. dir) from within the
system and exec functions in Php.

Can anyone help me figure out how to get ImageMagick to run from a Php
script - in Windows? I have tired using the full path to the convert
command, but that does not change anything (the ImageMagick installation
adds itself to the PATH environment variable anyway).

TIA

You probably need to escape the \ characters, or switch them around so
they're / instead.

You know you need to escape backslashes in strings, right?

Thanks for the replies. I must admit that I was being a little ignorant
on that count ... but, I had already tried reversing the slashes:

system("convert .exe C:/apache/htdocs/testing/temp_.jpg
C:/apache/htdocs/testing/temp_.png", $retval);

and after these two replies, I tried escaping the backslashes:

system("convert .exe C:\\apache\\htd ocs\\testing\\t emp_.jpg
C:\\apache\\htd ocs\\testing\\t emp_.png", $retval);

But both methods still gave me a retval of 1.

However, I then tried using a relative path - or no path (leave off the c:):

system("convert .exe temp_.jpg temp_.png", $retval);

or (placing the images in a sub folder)

system("convert .exe photos/temp_.jpg photos/temp_.png", $retval);

and then it it works.

It seems that I can not use an absolute path
(c:\apache\htdo cs\testing\temp _.png). I'm not sure why the c: part is a
problem, but using relative paths is all I really need to do. I was only
using full paths to be sure I was pointing to the right location of the
files while testing.

Thanks for the help.
