function rel2abs($rel, $base)
{
/* return if already absolute URL */
if (parse_url($rel, PHP_URL_SCHEME) != '') return $rel;
/* queries and anchors */
if ($rel[0]=='#' || $rel[0]=='?') return $base.$rel;
/* parse base URL and convert to local variables:
$scheme, $host, $path */
extract(parse_url($base));
/* remove non-directory element from path */
$path = preg_replace('#/[^/]*$#', '', $path);
/* destroy path if relative url points to root */
if ($rel[0] == '/') $path = '';
/* dirty absolute URL */
$abs = "$host$path/$rel";
/* replace '//' or '/./' or '/foo/../' with '/' */
$re = array('#(/\.?/)#', '#/(?!\.\.)[^/]+/\.\./#');
for($n=1; $n>0; $abs=preg_replace($re, '/', $abs, -1, $n)) {}
/* absolute URL is ready! */
return $scheme.'://'.$abs;
}

我喜歡jordanstephens從鏈接提供的代碼！我投它。l0oky啟發了我，以確保該功能的端口，用戶名和密碼的網址兼容。我的項目需要它。
function rel2abs( $rel, $base )
{
/* return if already absolute URL */
if( parse_url($rel, PHP_URL_SCHEME) != '' )
return( $rel );
/* queries and anchors */
if( $rel[0]=='#' || $rel[0]=='?' )
return( $base.$rel );
/* parse base URL and convert to local variables:
$scheme, $host, $path */
extract( parse_url($base) );
/* remove non-directory element from path */
$path = preg_replace( '#/[^/]*$#', '', $path );
/* destroy path if relative url points to root */
if( $rel[0] == '/' )
$path = '';
/* dirty absolute URL */
$abs = '';
/* do we have a user in our URL? */
if( isset($user) )
{
$abs.= $user;
/* password too? */
if( isset($pass) )
$abs.= ':'.$pass;
$abs.= '@';
}
$abs.= $host;
/* did somebody sneak in a port? */
if( isset($port) )
$abs.= ':'.$port;
$abs.=$path.'/'.$rel;
/* replace '//' or '/./' or '/foo/../' with '/' */
$re = array('#(/\.?/)#', '#/(?!\.\.)[^/]+/\.\./#');
for( $n=1; $n>0; $abs=preg_replace( $re, '/', $abs, -1, $n ) ) {}
/* absolute URL is ready! */
return( $scheme.'://'.$abs );
}

添加了對保留當前查詢的支持。對？page = 1很有幫助，依此類推...
function rel2abs($rel, $base)
{
/* return if already absolute URL */
if (parse_url($rel, PHP_URL_SCHEME) != '')
return ($rel);
/* queries and anchors */
if ($rel[0] == '#' || $rel[0] == '?')
return ($base . $rel);
/* parse base URL and convert to local variables: $scheme, $host, $path, $query, $port, $user, $pass */
extract(parse_url($base));
/* remove non-directory element from path */
$path = preg_replace('#/[^/]*$#', '', $path);
/* destroy path if relative url points to root */
if ($rel[0] == '/')
$path = '';
/* dirty absolute URL */
$abs = '';
/* do we have a user in our URL? */
if (isset($user)) {
$abs .= $user;
/* password too? */
if (isset($pass))
$abs .= ':' . $pass;
$abs .= '@';
}
$abs .= $host;
/* did somebody sneak in a port? */
if (isset($port))
$abs .= ':' . $port;
$abs .= $path . '/' . $rel . (isset($query) ? '?' . $query : '');
/* replace '//' or '/./' or '/foo/../' with '/' */
$re = ['#(/\.?/)#', '#/(?!\.\.)[^/]+/\.\./#'];
for ($n = 1; $n > 0; $abs = preg_replace($re, '/', $abs, -1, $n)) {
}
/* absolute URL is ready! */
return ($scheme . '://' . $abs);
}
