[PHP-DB] fopen() question and auto update question

[Tony S . Wu]

has any of you have any problem with fopen() that it can't open some 
web page?
i am trying to use it to gather information from other web pages, but i 
am having problem with one particular website, macmall.com.
might anyone know what the problem is?
also, if there is no solution to this, i am going to have to abandon 
the idea by using fopen() to gather information.
can anyone suggest an alternative way, which won't cost me too much 
time to get to it?
there will be around 200 data to be updated each time.
thanks a lot.

[PHP-DB] fopen() question

[Tony]

I have a database and I am writing a script to auto-update some information
in the database.
That requires me to read data from database, find the URL, read the URL,
find the information I want, then update it in the database.
My problem is, for example I read one record from database who's URL is
http://www.somedomain.com/.
And I try to read the URL with fopen() for information:

$fp = fopen(³http://www.comedomain.com/², ³r²);

if (!$fp)
{
echo ³URL not available.²;
exit;
}

If the URL is available, things will work fine.
But if the URL is NOT available, I will get a error saying ³attempt to load
file ³MyFile¹s URL² failed² from browser.
It¹s supposed to output the string ³URL not available², isn¹t it?
Anyone know how to get around with this?

Also, if you check many URL's from the same script, make sure neither 
PHP nor the browser times out. For PHP, set_time_limit() and for the 
browser echo a space and flush() after each test.
