For Modified date of web page

Hi..

There is an example over on php.net that might do what you want.
It was posted by :solarijj at gmail dot com

and coping right from that page the PHP is as follows:

==============================================
// get remote file last modification date (returns unix timestamp)
function GetRemoteLastModified( $uri )
{
// default
$unixtime = 0;

$fp = fopen( $uri, "r" );
if( !$fp ) {return;}

$MetaData = stream_get_meta_data( $fp );

foreach( $MetaData['wrapper_data'] as $response )
{
// case: redirection
if( substr( strtolower($response), 0, 10 ) == 'location: ' )
{
$newUri = substr( $response, 10 );
fclose( $fp );
return GetRemoteLastModified( $newUri );
}
// case: last-modified
elseif( substr( strtolower($response), 0, 15 ) == 'last-modified: ' )
{
$unixtime = strtotime( substr($response, 15) );
break;
}
}
fclose( $fp );
return $unixtime;
}
=============================================

I hope this helps
