PHP下载生成表格的需求经常会使用到，代码可以一次性封装，以方便后续使用。

 

//exlcel表格下载函数function down_xls($data, $keynames,$oneway, $name='dataxls') {	$xls[] = "
     
     
      ";	$xls[] = "
';	foreach($data As $o) {		$line = array(++$index);		foreach($keynames AS $k=>$v) {			$line[] = $o[$k];		}		$xls[] = '
';	}	if($oneway)  $xls[] = '
';	$xls[] = '
      
       
        
ID
        
" . implode("
        
", array_values($keynames)) . '
       
       
        
'. implode("
        
", $line) . '
       
       
        
'.$oneway.'
       
      
     
';	$xls = join("\r\n", $xls);	header('Content-Disposition: attachment; filename="'.$name.'.xls"');	die(mb_convert_encoding($xls,'UTF-8','UTF-8'));}
