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($filename, p style=\padding-left: 45\font
face=\Verdana\ size=\3\b%[a-zA-Z0-9,. ]/b/font)) {
print_r($headlines);
}
fclose($filename);
What the fscanf() code -should- be doing, or at least what I intend for it
to do, is grab everything between p style=padding-left: 45...b and
/b/font - is my code structured for that?

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.

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.
Thanks,

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(|font face=\Verdana\ size=\3\b+[-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!

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(|font face=\Verdana\ size=\3\b(.*)/b/font|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 /b/font 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!

I think I'm pretty close to getting this right (maybe!), I've been reading
through the manual, but can't seem to work it out. I keep getting this
error:
[Mon Jul 22 19:03:24 2002] [error] PHP Warning: Supplied argument is not

valid File-Handle resource in index.php on line 66
I'm trying to open a URL, read the contents, then pull out specific info
found between specific HTML tags. This is what I have so far:
63| ?php
64| $filename =
fopen(http://www.kinyradio.com/juneaunews/latest_juneau_news.html;, r);
65| $contents = fread($filename, 100);
66| while($headlines = fscanf($filename, p style=\padding-left:

68| print a
href=\http://www.kinyradio.com/juneaunews/latest_juneau_news.html\;$headli
ne/abr;
69| }
70| fclose($filename);
71| ?
Any ideas? Any other functions I could try instead of fscanf()?
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;
}
