Need a little help....

Anon

Ok so I need a lot of help, I've read most of the manual, looked at some examples and can hack the code pretty well. I however have not been able to write a code that I want to use for something on my site.

Since the search function here is less then desireable for finding information.

I would like to create a script that when called it will open up the warnings file from here:
http://iwin.nws.noaa.gov/iwin/mo/allwarnings.html

It will read it line by line looking for the occurance of "SVRSGF", when it finds that occurance it will print out everything between that and "$$" which as you can see is text, it would then look for multiple occurances of the "SVRSGF" and "$$" and print that out too, It must be printed out how it appears and not jumbled up :-p.

Can anyone write me a chunk of code or point me to a script that maybe already does something like this???

Thanks!

$fp = fopen("http://iwin.nws.noaa.gov/iwin/mo/allwarnings.html", "r");

$text = "";
while(!feof($fp)) {
$line = fgets($fp, 4096);
if ($line == "SVRSGF") {
do {
$text .= $line;
$line = fgets($fp, 4096);
} while ($line != "$$");
}

print "<PRE>$text</PRE>";

That should do it, although I didn't see any $$ in the file.

No go sir. It prints out nothing, I even changed the SVRSGF and $$ markers to 2 different lines that were at the top of the file, that should have worked. No errors and no data :-(

So I changed the <PRE>$text</PRE> to $line and it prints the last line of the file, but at least it prints something :-)

Do you know what's wrong??

If it only prints the last line I would guess that you missed the . in the .= statements. Post the code you wrote and I'll take a look at it.

I copied the exact same code you gave me. But I changed the "SVRSGF" to "SVRPAH" because it existed at the top of the list at that time. It also had the $$ at the bottom of the entry.

<?php
$fp = fopen("http://iwin.nws.noaa.gov/iwin/mo/allwarnings.html", "r");

$text = "";
while(!feof($fp)) {
$line = fgets($fp, 4096);
if ($line == "SVRPAH") {
do {
$text .= $line;
$line = fgets($fp, 4096);
} while ($line != "$$");
}

print "<PRE>$text</PRE>";
?>

Here you go:

<?php
$fp = fopen("http://iwin.nws.noaa.gov/iwin/mo/allwarnings.html", "r");

$text = "";

while(!feof($fp)) {
$line = fgets($fp, 4096);
if (substr($line, 0, 6) == "NPWSGF") {
do {
$text .= $line;
$line = fgets($fp, 4096);
} while (substr($line, 0, 2) != "$$");
}
}
fclose($fp);

print "<PRE>$text</PRE>";
?>

You were missing a closing } and it turns out that you need to specify what parts of the text you are searching. So I added the substr() function to your tests to make sure the characters appeared in the proper location. Also I had to change what you were looking for since there wasn't the item you were looking for on that page today.

Exactly what I was wanting, Thanks for your help sir :-)
