That error indicates that fopen failed to open the requested file. Given
that the URL works fine in a browser, is it possible that your php is not
configured to do remote fopen? Check the setting of allow_url_fopen in
phpinfo()
It is a good idea to test the result of such calls before trying to use
the result:
fopen('Whatever') or exit('Couldn't get it, Boss!');
or
if(fopen('whatever') {
do good things;
}else{
bleat vigorously;
}

RE: [PHP] Re: Using fopen()/fread()/fscanf()
I'm fairly certain that fopen() is working fine - I can echo "$contents";
and it works great, but it displays the entire page that I fetched. I just
want certain parts of the page and unfortunately, fscanf() doesn't seem to
think $contents or $filename are valid. Just more info on this, I tried
replacing fscanf($filename,...) with fscanf($contents,...) and got the same
result.

RE: [PHP] Re: Using fopen()/fread()/fscanf()
I'm thinking that you need to remove the:
$contents = fread($filename, 100);
line. This is probably making the file pointer point to the end of the file.

RE: [PHP] Re: Using fopen()/fread()/fscanf()
Okay, I removed that line and I no longer get the invalid File-Handle
resource error, but I also don't get anything useful. Maybe my fscanf() line
needs some work? With this new code, if I print_r($headlines); I get 229 of
these: Array ( [0] => )
Code:
$filename =
fopen("http://www.kinyradio.com/juneaunews/latest_juneau_news.html";, "r");
while($headlines = fscanf($filename, "%[a-zA-Z0-9,. ]")) {
print_r($headlines);
}
fclose($filename);
What the fscanf() code -should- be doing, or at least what I intend for it
to do, is grab everything between mailto:[EMAIL PROTECTED]]

RE: [PHP] Re: Using fopen()/fread()/fscanf()
Alright, I see that this is probably the way to go, but I'm dying here. I
have this:
$filename =
fopen("http://www.kinyradio.com/juneaunews/latest_juneau_news.html";, "r");
$contents = fread($filename, 100);
preg_match_all("|+[-a-zA-Z0-9,. ]+|i",
$contents, $out);
print_r($out);
And it returns this:
Array ( [0] => Array ( [0] => Injured hiker [1] => Toy guns looked real
enough [2] => U-S Forest Service Chief visiting [3] => Millions in
compensation divided up [4] => Alaska Air [5] => One car [6] => Services [7]
=> Talkeetna ) [1] => Array ( [0] => Injured hiker [1] => Toy guns looked
real enough [2] => U-S Forest Service Chief visiting [3] => Millions in
compensation divided up [4] => Alaska Air [5] => One car [6] => Services [7]
=> Talkeetna ) )
This is definitely progress, but the headlines are truncated. I have a
feeling this has something to do with linebreaks, but I don't know how to
account for those. For example, $out[0][0] should read "Injured hiker
rescued on Mt. Juneau" and $out[0][2] should end with "...Alaska for the
first time".
The manual entries for preg_match and preg_match_all pretty much assume you
have a working knowledge of reg expressions, which I don't, and a google
search turned up a bunch of pages, none of which I could understand enough
to be of help. So, any pointers would be appreciated. Thanks!

Not sure why you're using fscanf() and why it doesn't work. I would use
preg_match() on $contents.

Assuming that the and tags are closed and you want everything in
between then try this:
preg_match_all("|(.*)|i",
$contents, $out);

You want to read up on "Pattern Modifiers" and "Pattern Syntax", that's where
all the regex black magic is explained.

RE: [PHP] Re: Using fopen()/fread()/fscanf()
I must be dumb because I still can't get it to work.
Using the following instead of my previous preg_match_all statement:
preg_match_all("|(.*)|i",
$contents, $out);
Gives me only the -last- 3 headlines on
http://www.kinyradio.com/juneaunews/latest_juneau_news.html. I've looked at
the source and there are indeed more matching tags than are being returned.
I've tried placing "r+" in my fopen() statement to put the pointer at the
beginning of the file, but no luck there. I've also tried a bigger filesize
constant in fread(), still nothing.
Actually, I just noticed what the difference is with those last three -
their lines don't break in the source. The other lines have breaks, so the
land on the following line. Is there anything I can do to have
preg_match_all 'connect' the lines?
Any help would be great. Thanks!
