OSX Apache : allow execution of shell command for PHP script - include path

Question

I am running a website on OSX server, that needs to execute pdftotext, which is installed in /usr/local/bin. However, there seems to be an issue with the command not being in the Apache path.

I first confirmed that I can execute shell scripts. <?php shell_exec('whoami'); ?> returns _www.

However, when I run the following :

 $cmd = 'has pdftotext 2>&- || echo 1';
 $out = shell_exec($cmd);
 echo $out;

it returns "1" meaning it cannot access the command.

The same command run from terminal returns nothing (I can access the program without any issue).

When I run shell_exec('env'."2>&1") /usr/local/bin is indeed not in the path. Where do I set it for Apache2 on OSX Mountain Lion Server ?

UPDATE

I found the answer as to how to modify the Apache PATH here: https://gist.github.com/thebigdog/5208619

I needed to modify /System/Library/LaunchDaemons/org.apache.httpd.plist, adding

<key>PATH</key>
<string>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin</string>

to the existing <key>EnvironmentVariables</key> definition. So in the end it looked like this:

<key>EnvironmentVariables</key>
<dict>
    <key>PATH</key>
    <string>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin</string>
    <key>SERVER_INSTALL_PATH_PREFIX</key>
    <string>/Applications/Server.app/Contents/ServerRoot</string>
    <key>XPC_SERVICES_UNAVAILABLE</key>
    <string>1</string>
</dict>

Once I restarted the Apache server, the path was added and the shell command was executed properly.
