php不使用插件导出excel的简单方法，首先获取需要导出的数据的数组，数组的格式在下面。

之后就是定义文件名称和需要导出的excel的样式，最后就是循环数组，输出数据了

代码：

$filename=date("Y年m月d日")."数据信息统计结果.xls";  //文件名
$ua = $_SERVER["HTTP_USER_AGENT"]; //中文文件名不乱码
if (preg_match("/MSIE/", $ua)) {
      $filename=urlencode($filename);
} else if (preg_match("/Firefox/", $ua)) {
      $filename=$filename;
} else {
      $filename=urlencode($filename);
}
header("Content-type:application/vnd.ms-excel");　//输出excel头
header("Content-Disposition:filename=".$filename);
$n = iconv('utf-8', 'gbk', '11'); //设置excel表格列
$t = iconv('utf-8', 'gbk', '22');
$k = iconv('utf-8', 'gbk', '33'); 
$s = iconv('utf-8', 'gbk', '44');
$r= iconv('utf-8', 'gbk', '55');
$a= iconv('utf-8', 'gbk', '66');
echo "{$n}\t";
echo "{$t}\t";
echo "{$k}\t";
echo "{$s}\t";
echo "{$r}\t";
echo "{$a}\t\n";
// www.jbxue.com
foreach($a as $kk=>$pp){//对每列些数据
foreach($pp['child'] as $k=>$p){
echo iconv("utf-8", "gbk//IGNORE", $pp['u']."\t");
echo iconv("utf-8", "gbk//IGNORE", $p['u']."\t");
echo iconv("utf-8", "gbk//IGNORE", $p['s']."\t");
echo iconv("utf-8", "gbk//IGNORE", $p['t']."\t");
echo iconv("utf-8", "gbk//IGNORE", $p['c']."\t");
echo iconv("utf-8", "gbk//IGNORE", $p['t']."\t\n");
}
}

数组格式为

[0] => Array

[unitid] => 1234
