this test.php file:

<?php $my_file = 'file.txt'; $handle = fopen($my_file, 'w') or die('cannot open file:  '.$my_file); //implicitly creates file

related question: why crontab not executing php script?.

you need use full paths in scripts. otherwise, cron won't know file.

so instead of

$my_file = 'file.txt'; 

use

$my_file = '/path/to/file.txt'; 

probably getting file.txt stored somewhere in /.

note crontab runs in limited environment, cannot assume regarding paths. that's why have provide full path of php, etc.

from troubleshooting common issues cron jobs:

using relative paths. if cron job executing script of kind, must sure use absolute paths inside script. example, if script located @ /path/to/script.phpand you're trying open file called file.php in same directory, cannot use relative path such fopen(file.php). file must called absolute path, this: fopen(/path/to/file.php). because cron jobs not run directory in script located, paths must called specifically.
