[SOLVED] Warning: socket_set_timeout():

drexnefex · January 4, 2007

Hello -

I am getting the following error: Warning: socket_set_timeout(): supplied argument is not a valid stream resource in /testbuoy4.php on line 179.

This script was working fine a few days ago and suddenly broke. I haven't edited the file recently and am completely stumped on why it's broken.

Any ideas out there?

# HOW TO USE phpBuoy #
######################
#
# phpBuoy is meant to be used as either a PHP
# or SSI include file, and of course must be
# used on a machine with PHP installed.
#
# There are a number of user-based customizations
# possible, most importantly the buoy station
# from which to parse the buoy reports.
# Please see below for details.

################################
# START OF USER CUSTOMIZATIONS #
################################

# Go to http://www.ndbc.noaa.gov/ and locate the station number
# of the buoy for which you want to get data. Enter that number
# below for $, and then provide whatever info you
# want display for the station on the output page as $stationName.

Set stream timeout AFTER the connection is established:

[code=php:0]
if($fpread = fopen($backend, 'r')) {
socket_set_timeout($fpread, 3);
$line = fgets($fpread, 1024);
}
[/code]

Appearantly the stream cannot be opened, remove @ to see why.

If you want to set a timeout for the connecting, consider fsockopen.

thanks for the reply.

i figured out the problem.

the script was parsing a series of txt files on a NOAA gov server. one of the files (the 1st in my array) isn't being served anymore due the Buoy that was recording wave data having been lost in the big winter storms we've been having out here.

i eliminated that from my array, changed my counter and it worked!
