php怎么导出EXCEL文件呢?如果是ThinkPHP,可能会想到用PHPExcel,但是这个组件在数据量大时会导致内存溢出,那么有没有其他好方法呢?下面介绍一种:

<head>\r\n
<meta http-equiv=Content-Type content=\"text/html; charset=utf-8\">\r\n
</head>\r\n
<body>";
$str .="<table border=1><head>".$headtitle."</head>";
$str .= $tdtitle;
foreach ($datas as $key=> $rt )
{
$str .= "<tr>";
foreach ( $rt as $k => $v )
{
$str .= "<td>{$v}</td>";
}
$str .= "</tr>\n";
}
$str .= "</table></body></html>";
header( "Content-Type: application/vnd.ms-excel; name='excel'" );
header( "Content-type: application/octet-stream" );
header( "Content-Disposition: attachment; filename=".$filename );
header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" );
header( "Pragma: no-cache" );
header( "Expires: 0" );
exit( $str );
}
