PHP 进度条函数的简单实例

function ShowPercent($now,$total) 
{ 
 $percent = sprintf('%.0f',$now*100/$total); 
 $html = '<table width="60%" style="border-collapse:separate" height="10" border="0" cellpadding="0" cellspacing="2" bgcolor="#fff"><tr>'; 
 $count=0; 
 $pertr = 30; 
 while($count < $total) 
 { 
  $bgcolor = $count < $now "'.$bgcolor.'"> </td>'; 
  $count++; 
  if($count%$pertr == 0) $html .= '</tr><tr>'; 
 } 
 $bgcolor2 = $now == $total "font-weight:bold;color:green;"':''; 
 $html .= '<td'.$bgcolor2.' colspan="'.($count%$pertr).'">'.$percent.'%</td></tr></table>';
