fopen not working (in MODX)

    Hi guys,
    I´m using MODX REVO and have the problem to get the following code to work.

    Heres my code-snippet:
    <?php
$handle = fopen("http://www.domain.com/some-page.asp", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
fclose($handle);
	
echo $contents;
?>


    This code works without any problem in a normal PHP-file on my webserver (outside of MODX!), but it doesn´t if I insert this code into a MODX-snippet (neither saved as a static file nor in database).

    The output?
    The modx-page, where i included the snippet via [[mysnippet] or [[!mysnippet]], is served as a totally blank page - the source-code is completly empty. No errors listed under "REPORT > ERROR LOG".
    I cleared the cache serveral times as well.


    When I try some other way, like "file_get_contents", there´s the same problem. In a single php-file (outside of MODX) it works, implemented into MODX is doesn´t.


    The whole problem is some kind of weird and too complicated to explain in all its details. The workaround I have to realise is to get the content of a parsed (ASP)file and just to output the content in my modx-page.

    Any ideas?
    Is there maybe some system variable in modx which blocks the fopen-command?

      There are other options to fetching the content of an external file. cURL comes to mind. AJAX also would do the job.

        the cURL options works (again) in an external (php) file, inside of modx the output is still blank (as described above).

        $url = 'http://www.domain.com/some-file.asp';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
 
echo $data;


        Am I the only one with such problems? Don´t understand why that code is not executed by modx.

        AJAX, ...that could be an option.

          Have you tried returning your value rather than echo it? I believe this is the way it's supposed to be handled in Revo. 

          <?php
$handle = fopen("http://www.domain.com/some-page.asp", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
fclose($handle);
     
return $contents;
?>

            Yes, I tried it in this way too, with no success.

            But, finally, I got two solution to work with:
            1) use the AJAX way (like sottwell noted)

            2) to use the following code:

            ob_start();
include("http://www.domain.com/some-file.asp");
$yourfile = ob_get_clean();

echo $yourfile;



            thx for help.
