[file_get_contents]: failed to open stream "need help"

Hello,
I've got the following problem:
I want to include the googleSearch into my wiki.
Therefore I use the following implementation for mediawiki:

<?php

# Created by Matt Hart, Intuit, Inc. http://meta.wikimedia.org/wiki/User:MHart
# Note that this is not really an extension in the scrict sense - it isn't added
# to the extensions list and such. Rather it replaces the search.

function wfGoogleSearch( $par='' ) {

global $wgRequest, $wgUser;
global $wgOut, $wgSitename;
global $wgScriptPath;

$searchPage = new SpecialSearch( $wgRequest, $wgUser );

$search = $wgRequest->getText( 'search', $par );
$start = $wgRequest->getText( 'start', $par);

$wgOut->setPageTitle($search . " - Google Search");

$sitesearch = urlencode($_SERVER["HTTP_HOST"] . $wgScriptPath);

# Google URL Parameters
# site=ext_name  : this is the Google appliance (GA) "collection" to search
# client=name    : this is the GA client that is allowed to make requests
# as_sitesearch= : this restricts the results to this specific wiki, even on shared domains
#                  so wikis.intuit.com/first  gets its own results
#                        likewise wikis.intuit.com/second gets its own
$url = 'http://googlesearchurl.yoursite.com/search?q=' . urlencode($search) . 
'&output=xml&site=
ext_name&client=name&as_sitesearch=' . $sitesearch . '&start=' . $start;

$xmldata = file_get_contents($url);

# This saves the file to a temp location so that XSLTPROC can
# run on it. If you have Sablotron installed with PHP 5, you can
# use it's XSLT functions. The following method, however, works with
# any version of PHP.

$xmlfile = tempnam("","");
$file = fopen($xmlfile,"w");
fwrite($file,$xmldata);
fclose($file);

$results = xsltproc('extensions/Google.xslt',$xmlfile);

$wgOut->addHTML($results);

unlink($xmlfile);

$wgOut->output();
return;
}

function xsltproc($xslfile, $xmlfile)
{
    $toexec = "xsltproc " . $xslfile . " " . $xmlfile;
    exec($toexec,$results);
    return implode("",$results);
}
?>

Code (markup):

For the url: googlesearch.yoursite.com I use my local directory, where I am testing my extension: http://localhost/wiki/index.php/

If i am now testing this extension, searching for a word, there will appear the following fault:[file_get_contents]: failed to open stream: HTTP request failed!

Can you help me?
I'm disappointed that i cannot correct the mistake by my own..

Best regards,
Daniel

Try putting this right before the line that calls file_get_contents.
ini_set ('allow_url_fopen', 1);

 

try something in the line of

ob_start();
$xmldata = ob_get_contents($url);
 ob_end_clean();

Code (markup):

 

could be from this one:

$url = 'http://googlesearchurl.yoursite.com/....

Code (markup):

 

$xmldata = file_get_contents($url);

Code (markup):

make sure that $url doesn't end in a space (or tab, or newline... ), I was helping a guy who couldn't get file_get_contents() just to day and he took a list of URL and exploded them but forgot to use rtrim() to remove extra stuff and it gave him errors.

---- ---
also, is the URL a real website?

 

That works,
but now there follows another error:

Call to a member function getID() on a non-object in..
(this line)

if ( $wgOut->isArticle() and (!isset( $oldid ) or isset( $diff )) and 0 != $wgArticle->getID() )

Code (markup):

and this line I think refers to another file where I changed the normal SearchEngine:

if( !$this->getVal('DisableInternalSearch') && !is_null( $search ) && $search !== '' ) {
     // Commented OUT the default search
     // require_once( 'includes/SpecialSearch.php' );
     // $title = Title::makeTitle( NS_SPECIAL, 'Search' );         
     // wfSpecialSearch();
     // Add GoogleSearch here AND see the line below where it's added
     wfGoogleSearch();} 
else if( !$title or $title->getDBkey() == '' ) {
     $title = Title::makeTitle( NS_SPECIAL, 'Badtitle' );
     # Die now before we mess up $wgArticle and the skin stops working
     throw new ErrorPageError( 'badtitle', 'badtitletext' );
} else if ( $title->getText() == 'Search') {
     wfGoogleSearch();
} else if ( $title->getInterwiki() != '' )...

Code (markup):

Any ideas why this error occurs?Is the index of the "Search"Array zero and generates this one?

 

Oh, I haven't seen a fault in the description of this extension, so this topic is closed because it's no longer interesting for me. Thanks for your help!
