[Resolved] require when using cron to fie command line script

houltd

my web app sits in a folder called app,
there is a config.php file in this folder that contains some constants, eg database connection variables etc.etc

i want to run a script: app/scripts/dosomthing.php from cron every so often, but it fails saying it can't find the config.php file.

i require it like so:
<?php
require '../config.php';
?>

it works fine if you hit that scipt through the web browser, or on the command line, but gets error through cron.

anyone have any ideas?

you can always try
require "/full/path/to/config.php";
if its not working with the parent ../ method.

i just don't want to hard code the directory. so when we move it around i don't have to change anything in the code.

i did add the HOME=/pathtoscripts/ in the crontab file and that seems to have fixed it.

Is there any other way of doing it?

you can use $SERVER['DOCUMENT_ROOT'] instead of the home directory. that way if its in /home/username/public_html/folder/config.php you just do
require $SERVER['DOCUMENT_ROOT'] . "/folder/config.php";
and no matter where its moved as long as folder is in the document root it should work.-

hmm, that leads me to another option:

grab the $_SERVER['SCRIPT_NAME'] and just cut the last directory off....

drew010

yeah thats not a bad idea...

require $SERVER['DOCUMENT_ROOT'] . dirname($SERVER['SCRIPT_NAME']) . "/config.php";

that will use the document root and chop the filename off the directory path to the script.
