PHP Internal Function(s) Missing?

[KeithAbbott]

I just upgraded from 6.10.3 to 6.11.5, no real issues with the upgrade.  I see that Unraid now has PHP included, which is really nice.  However, I am trying to execute a small PHP script from the Unraid Terminal, using the following command:

 

php -f /mnt/user/sagemedia/pictures/DeleteOrphanedRecordingFiles.php

 

I get the following error:

 

Fatal error: Uncaught Error: Call to undefined function  scandir() in /mnt/user/sagemedia/pictures/DeleteOrphanedRecordingFiles.php:18

 

scandir is a PHP internal/built-in function (since version 5), so I'm not sure what I am doing wrong that Unraid's PHP is not recognizing it.  Any ideas?

This works fine for me, try adding #! and <?php to the code. chmod +x and then run the file.

I added #! as the first line, and changed the permissions for the .php file to 777.  I already had <?php in the code.  Still getting exact same error message as before.  Here is the stripped down php script that I am executing:

 

#!/usr/bin/php

<?php

$files2 = scandir('/tmp');

?>

Not sure why this does not run for you.

It seems to be working now.  I think I was supplying an invalid directory name to the scandir function, and the error that was being returned was a red herring.  Thanks for your help, SimonF!

 

p.s. Turns out that wasn't the root cause of the problem.  I was pasting in some code snippets, and what looked to be spaces in the code were actually a non-space character.  Once I figured that out and over-typed with actual spaces, everything started working smoothly.  I sure was getting some strange results until I found the actual problem.
