[SOLVED] Question about my PHP Script

[sjxx]

Hey,

To start off , I am a total noob to PHP but I have done a fair share of research on it and tried making my own script.

 

The script I am trying to make is supposed to do the following

 

Check a website ( www.example.com ) for files

Ex:

It should check for this

www.random.com/1.wmv

www.random.com/1.avi

--------------------

www.random.com/2.wmv

www.random.com/2.avi

--------------------

www.random.com/3.wmv

www.random.com/3.avi

----------------------

ETC.....

The script should do this all the way up to a 100 and then echo back to me with information whether the file/video exists or not

 

 

 

 

 

Here's something I got so far

 

 

 

 

<?php

for ($i=1; $i<101; $i++)
{
echo "www.seajist.100webspace.net/".$i.".wmv<br>/n";
echo "www.seajist.100webspace.net/".$i.".avi<br>/n";
}


?>

 

 

Then I assume I should combine it with something like this

 

 

<?php
$filename = 'www.seajist.100webspace.net/71.avi';

if (file_exists($filename)) {
    echo "The file $filename exists";
} else {
    echo "The file $filename does not exist";
}
?> 

 

 

The problem is, I don't know how to sort of combine the two to work in the way I need it.

Could anyone possibly help =)

 

Thanks,

-SJ

http://us2.php.net/file_exists

file_exists is only for files on your server, it won't (AFAIK) work for URLS (which btw, need to begin with http://)

 

Try get_headers perhaps?

http://us2.php.net/manual/en/function.get-headers.php

[sjxx]

I appreciate the quick reply but I am trying to check for files on a remote server so I would have to use the fopen()

 

Would this work?

 

 

<?php

for ($i=1; $i<101; $i++)
{
$filename_avi = 'www.seajist.100webspace.net/'.$i.'.avi';
$filename_wmv = 'www.seajist.100webspace.net/'.$i.'.wmv';

  if (fopen($filename_avi)) {
      echo "www.seajist.100webspace.net/".$i.".avi<br />/n";
  } else {
      echo "The file ".$filename." does not exist<br />/n";
  }
  if (fopen($filename_wmv)) {
      echo "www.seajist.100webspace.net/".$i.".wmv<br />/n";
  } else {
      echo "The file ".$filename." does not exist<br />/n";
  }
}


?>

you will have a long code using that try this first

http://us2.php.net/file_exists

file_exists is only for files on your server, it won't (AFAIK) work for URLS (which btw, need to begin with http://)

 

Try get_headers perhaps?

http://us2.php.net/manual/en/function.get-headers.php

 

 

[matthewhaworth]

If PHP has decided that filename specifies a local file, then it will try to open a stream on that file. The file must be accessible to PHP, so you need to ensure that the file access permissions allow this access. If you have enabled safe mode, or open_basedir further restrictions may apply.

 

If PHP has decided that filename specifies a registered protocol, and that protocol is registered as a network URL, PHP will check to make sure that allow_url_fopen is enabled. If it is switched off, PHP will emit a warning and the fopen call will fail.

 

Thought it might interest you..

 

http://uk.php.net/manual/en/function.fopen.php

[teng84]

why do you need to use fopen when all you want is to check if that thing exist?????????????????

[sjxx]

I already looked at that website but I am not sure how to associate the fopen with my needs =/

[sjxx]

Ya, I don't need to open/stream the file, I just need a verification that "File number ## Exists"

^I tried the above script but the page is just all blank, which I assume is incorrect because it should have found the 77.avi on the server

[Jessica]

Did you try it with http://www...I think it has to be http:// not just www.

[sjxx]

I added in http://www. but the page is still blank

[Jessica]

Take out the www.

 

Look at the URL you're trying to access.

www.seajist.100webspace.net/77.avi

Actually go to it in your browser. Is anything there? No.

 

Google "subdomains". Your site is not www.seajist.100webspace.net/ it is http://seajist.100webspace.net/

http://seajist.100webspace.net/77.avi HAS a file.

[sjxx]

Yes I know but it isn't my site I am trying to look for files, it was just an example.

Here is the script I am currently using modified to my needs

 

<?php

  for ($i=1; $i<=100; $i++) {
    $filename_avi = 'http://www.xspand.ca/'.$i.'.avi';
    $filename_wmv = 'http://www.xspand.ca/'.$i.'.wmv';
    $ok = @get_headers($filename_avi);
    if (preg_match("|200|", $ok[0])) {
      echo "$filename_avi<br />/n";
    } else {
      echo "The file ".$filename_avi." does not exist<br />/n";
    }
    $ok = @get_headers($filename_wmv);
    if (preg_match("|200|", $ok[0])) {
      echo "$filename_wmv<br />/n";
    } else {
      echo "The file ".$filename_wmv." does not exist<br />/n";
    }
  }

?>

 

 

Either way, the PHP page returns blank

[Jessica]

Take out the error supression sybmol: @ everywhere.

The file:

http://www.xspand.ca/77.avi

 

Doesn't exist there either. Do you have an example of a url that actually exists?

[sjxx]

No I don't have an actual example

The example I was using to test was the seajist.100webspace.net/77.avi

 

 

Here is the error after removing @

 

 

Fatal error: Call to undefined function: get_headers() in /home/www/seajist.100webspace.net/omg.php on line 6

[Jessica]

Are you using PHP4? get_headers is a PHP5 function only.

http://us.php.net/manual/en/function.get-headers.php

 

If you scroll down through the comments it looks like someone has posted a function to emulate it, that will work in 4.

[sjxx]

Yes I am,

The free service from 100webspace I am using says PHP 4/5 Support

[Jessica]

You'll probably need to contact them to see how to get it switched to PHP5 for all your pages.

 

This is how I force PHP5 on my server on MT. It may/may not work for you, but it's worth a shot.

Save this code as simply .htaccess and upload it to your site:

AddHandler php5-script .php

[sjxx]

I added that and it made it so I couldn't view my php file, it automatically asks me to download it if I try to view it

[Jessica]

You need to contact your host then. If it says the function is not found, then it sounds like you're running PHP4, not PHP5.

You can also try changing the file extension from .php to .php5 but I think it will have the same result. (Remove the .htaccess file tho.)

[sjxx]

nevermind, got it working =D
