how to retrieve and echo a remote page?

[angelcool]

Hello community,

 

I want to retrieve and echo a remote web page using php (perhaps php as a client).

 

Example:

 

File to retrieve: http://10-network.net/angelcool.net/cisw21/index.htm

 

PHP file retriever: http://10-network.net/test.php

 

As you can see my cute face does not get retrieved  .

 

Is there any way possible to display the image? Perhaps using a different technique(cURL,fopen etc.)?

Another issue to note is the lack of CSS on the links.

 

code in php file:

 

<?php

 

$file = file_get_contents("http://10-network.net/angelcool.net/cisw21",'r');

 

echo $file;

?>

 

I was thinking a way to solve this is a function to string replace the relative paths for the CSS file and the image from relative to absolute in the PHP file retriever.

 

Any better suggestion will be apreciated.

 

I will apreciate any suggestions/help.

 

Thank you

 

Angel

angelcool,

 

  When you right-click on your missing image and select Properties, it says that the image is: 10-network.net/yummy.jpg , but if you enter:

 

  http://10-network.net/yummy.jpg into a browser, you get 404: The requested URL /yummy.jpg was not found on this server.

 

  I would check test.php to see how you are building your <img element.

I was thinking a way to solve this is a function to string replace the relative paths for the CSS file and the image from relative to absolute in the PHP file retriever.

 

That's what I would do. More specific, search for href="*" and src="*" (using regular expressions), and replace the paths with absolute paths.

 

This functions works for converting the paths:

 

<?php
// http://w-shadow.com/blog/2007/07/16/how-to-extract-all-urls-from-a-page-using-php/
function relative2absolute($absolute, $relative) {
        $p = @parse_url($relative);
        if(!$p) {
        //$relative is a seriously malformed URL
        return false;
        }
        if(isset($p["scheme"])) return $relative;

        $parts=(parse_url($absolute));

        if(substr($relative,0,1)=='/') {
            $cparts = (explode("/", $relative));
            array_shift($cparts);
        } else {
            if(isset($parts['path'])){
                 $aparts=explode('/',$parts['path']);
                 array_pop($aparts);
                 $aparts=array_filter($aparts);
            } else {
                 $aparts=array();
            }
           $rparts = (explode("/", $relative));
           $cparts = array_merge($aparts, $rparts);
           foreach($cparts as $i => $part) {
                if($part == '.') {
                    unset($cparts[$i]);
                } else if($part == '..') {
                    unset($cparts[$i]);
                    unset($cparts[$i-1]);
                }
            }
        }
        $path = implode("/", $cparts);

        $url = '';
        if($parts['scheme']) {
            $url = "$parts[scheme]://";
        }
        if(isset($parts['user'])) {
            $url .= $parts['user'];
            if(isset($parts['pass'])) {
                $url .= ":".$parts['pass'];
            }
            $url .= "@";
        }
        if(isset($parts['host'])) {
            $url .= $parts['host']."/";
        }
        $url .= $path;

        return $url;
}
?>

 

preg_replace() should be able to do it all in one run; untested code below. Also, what's the second parameter for, in your file_get_contents()?

 

<?php
$abs_url = 'http://10-network.net/angelcool.net/cisw21/index.htm';
$page = file_get_contents($abs_url);
$find = array(
'~href="(.+?)"~ise',
'~src="(.+?)"~ise'
);
$replace = array(
"'href=\"'.relative2absolute($abs_url, '\\1').'\"'",
"'src=\"'.relative2absolute($abs_url, '\\1').'\"'"
);
$page = preg_replace($find, $replace, $page);
echo $page;
?>

Just tested the code and noticed a small error. Forgot to enclose $abs_url in quotes inside the $replace array. This works:

 

<?php
$abs_url = 'http://10-network.net/angelcool.net/cisw21/index.htm';
$page = file_get_contents($abs_url);
$find = array(
'~href="(.+?)"~ise',
'~src="(.+?)"~ise'
);
$replace = array(
"'href=\"'.relative2absolute('$abs_url', '\\1').'\"'",
"'src=\"'.relative2absolute('$abs_url', '\\1').'\"'"
);
$page = preg_replace($find, $replace, $page);
echo $page;
?>

Wow, that function really works!

 

Thank you!
