$tabs[ count( $tabs ) - 1 ][ 'text' ] = $text;  
ob_start();

function tab( $title )   
{  
global $tabs;  
if ( count( $tabs ) > 0 )  
endtab();

text => ""  
);  
}  
 
function tabs_end( )  
{  
global $tabs;  
endtab( );  
ob_end_clean( );  
$index = 0;  
if ( $_GET['tabindex'] )  
$index = $_GET['tabindex'];  
?> 
< table width="100%" cellspacing="0" cellpadding="0"> 
< tr> 
< ?php  
$baseuri = $_SERVER['REQUEST_URI'];  
$baseuri = preg_replace( "/?.*$/", "", $baseuri );  
$curindex = 0;  
foreach( $tabs as $tab )  
{  
$class = "tab";  
if ( $index == $curindex )  
$class ="tab-active";  
?> 
< td class="< ?php echo($class); ?>"> 
< a href="< ?php echo( $baseuri."?tabindex=".$curindex ); ?>"> 
< ?php echo( $tab['title'] ); ?> 
< /a> 
< /td> 
< ?php  
$curindex += 1;  
}  
?> 
< /tr> 
< tr>< td class="tab-content" colspan="< ?php echo( count( $tabs ) + 1 ); ?>"> 
< ?php echo( $tabs[$index ]['text'] ); ?> 
< /td>tr>
