PHP use of undefined constant error

php undefined constants
14,311

You (or the script's author) needs to put sys_get_temp_dir into quotes:

 if (function_exists("sys_get_temp_dir")) {

this was not meant to be a constant.

    Using a great script to grab details from imdb, I would like to thank Fabian Beiner.

    Just one error i have encountered with it is:

    Use of undefined constant sys_get_temp_dir assumed 'sys_get_temp_dir' in '/path/to/directory' on line 49

    This is the complete script
