Script runs OK from browser but not from PHP CLI.

My php script isn't connecting to the noaa.gov server and fetching weather reports when it's run from a cron jon. However, when I run the script from a browser it works fine and connects and fetches the weather report for a given airport. The script then parases it into an MySql table.

When the script runs from the cron job, the MySQL table is empty - indicating that it didn't fetch the weather data from noaa.gov.

Can anyone see anything in my code below that would cause it to not work from the CLI yet work when run from a browser?
BTW - there is no html code in my script. I write debug data to a file so I know how the script ran. When I run the script from a browser the web page is blank.

$php_resultID = mysql_query($php_SQL, $php_linkID);
