Do you want to output a dynamic link on your site?

<a href="<?php print ?>">Link</a>

<a href="<?php print $myvariablelink ?>"><?php print $myvariable title ?></a>

<?php print "<a href="$myvariablelink">$myvariabletitle</a>" ?>

Are you wanting to forward the user to a different page? (Must be sent before any output is printed.)

<?php
header( "Location: );
exit;
?>

or (can be executed after output has already been sent to the browser, but requires javascript or a click)

<?php
print '<script language="javascript">window.location =
print '<noscript>Please click <a to move along</noscript>';
?>

Do you want to read in another web page and output it on your own? (Requires allow_url_fopen to be enabled in the configuration.) Be careful about doing this sort of thing, because if a hundred people hit your page, your server makes one hundred sudden requests to download. If this is the route you're after, look into cacheing/saving the result for a period of time or get fancy and ask the web server if the page has been updated.

<?php
$url =
$f = fopen( $url, "r" );
if( !$f ) die( "Could not open $url for reading" );
while( !feof( $f ) ) {
$data = fread( $f, 1024 );

// Print it out
print $data;

// Or store it in a variable
$text .= $data;
}
fclose( $f );
?>

Hope that helps.
