get url from a webpage

[maddali]

Hi folks,

 

I was wondering if there is any code that can get the url's that's in a webpage....

 

here is the page I'm referring to....I need this url http://hdl.handle.net/1920/5657 ,which is in http://omars.gmu.edu/items/show/2536...

 

 

[newbtophp]

<?php

$file = file_get_contents("http://omars.gmu.edu/items/show/2536");

preg_match("/<div class=\"element-text\">http:\/\/([a-z0-9\/\.]*)<\/div>/i", $file, $matches);

echo $matches[0];

?>

It worked...Thanks

 

Can the url in the file_get_contents be replaced with $_SERVER['REQUEST_URI'],so that I get a dynamic function which get the Identifier's url of the current page....

[maddali]

<?php

$tem=$_SERVER['REQUEST_URI'];

echo "$tem";

$file=file_get_contents("$tem");

 

preg_match("/<div class=\"element-text\">http:\/\/([a-z0-9\/\.]*)<\/div>/i",$file,$matches);

 

$temp=$matches[0];

echo $temp;

 

I'm trying to write a code that takes the current url and get the url link in that webpage.I'm sure I went wrong somewhere in the line 4,where file_get_contents should accept the current url of $tem.Can somebody correct the code please

 

Thanks

Access it like pagename.php?url=http://omars.gmu.edu/items/show/2536

 

<?php

$url = strip_tags($_GET['url']);

if(isset($url)){
$file = file_get_contents($url);

preg_match("/<div class=\"element-text\">http:\/\/([a-z0-9\/\.]*)<\/div>/i", $file, $matches);

echo $matches[0];

}
?>
