Checking if a .gif file exists

[batman]

<?php 
$file = "http://free.x3.hu/bighed/valami.zip";
$fp = fsockopen ($file, 80); 
if (!$fp) 
{ 
echo "<img src=\"status_red.gif\" height=\"20\" width=\"20\">"; 
} 
else 
{ 
echo "<img src=\"status_green.gif\" height=\"20\" width=\"20\">"; 
} 
?>

Try that,

[Bighed]

I got this error message:

Warning: fsockopen() [function.fsockopen]: php_network_getaddresses: gethostbyname failed in C:\www\bighed\bighed_temp\ping\file.php on line 3

Warning: fsockopen() [function.fsockopen]: unable to connect to http://free.x3.hu/bighed/valami.zip:80 in C:\www\bighed\bighed_temp\ping\file.php on line 3

The first parameter of fsockopen() is the domain isn't it?

But how can I put in the file name?

[batman]

<?php  

$file = "http://free.x3.hu/bighed/valami.zip"; 
$fp = fsockopen ($file, 2082);  

if (!$fp)  

{  

echo "<img src=\"status_red.gif\" height=\"20\" width=\"20\">";  

}  

else  

{  

echo "<img src=\"status_green.gif\" height=\"20\" width=\"20\">";  

}  

?>

Just keep changing the # after the $file till it works. I am not sure what socket number it is.

[Bighed]

And where can I watch this number?

It's different on all server or not?

[batman]

Not sure. Try the code I posted above and see if it works with the number 2082.

[Bighed]

It isn't working. :mad:

[Bighed]

I think that the problem is not the socket number...

I wrote a script which tries the socket numbers and I tried the first 11000 numbers!

So it's not good..

A question: Is this url correct??? http://free.x3.hu/bighed/valami.zip:2654

So the socket number comes behind the file name?

Anything else?

[batman]

Yes the socket number comes after. yes the url is correct. No, I don't have any more ideas. 🙂 sorry about that.

[Bighed]

OK, no problem! 🙂

But I discowared why I get always green picture!!!
If the file doesn't exists, I get the 404 error which is always exist, so I always get the green pic.

[batman]

Yes, forgot about that. 🙂 I used to have a way around this, but forgot how. LOL If I remember, I'll tell you.

[Xoid]

hmm..

[Bighed]

Hi!

Thanx for the script, but the problem is the same:
I always get the "File found" message, because of the 404 error.

[Xoid]

yeah, I thought I had it working then, now it's not, strange but true 🙁

[Xoid]

ok, try this, from my system this is working;

hope it works for you 😉

<?php

$file = "http://free.x3.hu/bighed/index.html";

$fp = fopen($file,"r");

$getid = substr($fp,strlen($fp)-1);

if( (integer)$getid==2 )
{
print "Could not open file or file does not exist";
}
else {
print "File Found $file";
}

fclose($fp);

?>

[Xoid]

btw - make sure that allow_url_fopen is set to [On] on the server that your using, it probably won't work for all servers dependant upon the setting but On is the default setting.

but again, hope it helps!

[Bighed]

It's much better and it's working!

Thank you Xoid!

[Bighed]

My homepage is on a free server, and fopen disabled 🙁

But the script is good...

[Xoid]

hmm... are you sure that file_exists() doesn't work? I've tried fsockopen but it doesn't work either.

apart from the solution I posted I don't really know what else to try, sorry 🙁
