PHP实现excel导出

   /**excel导出数据
     * @param $xlsName 文件名称
     * @param array $titleArr 文件标题
     * @param array $dataArr 数据
     */
    function excel_out($xlsName, array $titleArr, array $dataArr) {
        if (empty($titleArr) || empty($dataArr)) {
            die('error');
        }
        date_default_timezone_set('PRC');//设置时区
        set_time_limit(0);
        //设置header头信息
        Header("Content-Type:application/vnd.ms-excel;charset=UTF-8");
        Header("Accept-Ranges:bytes");
        Header("Content-Disposition:attachment;filename=".$xlsName.'_'.date('YmdHis').".xls");
        Header("Pragma:no-cache");
        Header("Expires:0");
        
        $str = $str2 = '';
        foreach ($titleArr as $field => $name) {
            $str .= trim(iconv("UTF-8","GBK", $name)) ."	";
        }
        $str .= "
";
        echo $str;
        foreach ($dataArr as $k => $v) {
            foreach ($titleArr as $field => $name) {
                $str2 .= trim(iconv("UTF-8","GBK", $v[$field]))."	";
            }
            $str2 .= "
";
        }
        echo $str2;
        die;
    }

使用示例：

$res  = array(
            array("name"=>'张三','sex'=>'男','age'=>20,'tel'=>'17895623145','id_number'=>"15616619941025152X"),
            array("name"=>'李四','sex'=>'女','age'=>25,'tel'=>'17895623145','id_number'=>"156166199410251520"),
            array("name"=>'王五','sex'=>'男','age'=>20,'tel'=>'17895623145','id_number'=>"156166199410251528"),
        );
$xlsName = '用户信息表';
$xlsCell = ['name'=>'姓名','sex'=>'性别','age'=>'年龄','tel'=>'手机号','id_number'=>'身份证号'];
foreach ($res as $key=>&$val) {
     //防止数字过长 变成科学计数法 1.56166E+17
     $val['tel'] = ':'.$val['tel'] ;
     $val['id_number'] = ':'.$val['id_number'];
}
excel_out($xlsName, $xlsCell, $res);

这样的excel就导出下来喽……见下图
