fopen, FTP, and error trapping

[boone]

Hi all.

I have a PHP script that runs as a cron job. It compiles some data and then uses the fopen command to FTP the file to a remote server.

The script works fine, and the FTP works fine, most of the time. However, when the FTP connection cannot be made, or fails in some other way, my script doesn't know how to deal with it.

Is there a proper procedure for FTPing files with fopen, and then subsequently verifying that it all went well?

Or should I compile in the PHP FTP functions for this level of control?

Thanks.

I had to do this same thing at my previous job, and from my experience, yes, using the PHP FTP functions worked great. You'll be able to trap erorrs at each point, which will help a lot when debugging.

The simplest form of error trapping is this:

if (!$fp = fopen(bla))
{
// error opening file, do what needs to be done
}
else
{
// file opened, write the file
};
