将数据输出到Excel表格中的方法

1.第一种

<?php
	$str = '';
	$str = '<table border = "2">
				<thead>
					<tr>
						<th>顶顶顶顶顶顶顶顶顶顶顶顶顶顶</th>
						<th>2</th>
						<th>3</th>
						<th>3</th>						
					</tr>
				</thead>
				<thead>
					<tr>
						<th>1</th>
						<th>2</th>
						<th>3</th>
						<th>3</th>						
					</tr>
				</thead>				
	';
	$filename = '11111111';
	header("Content-type:application/vnd.ms-excel");
	header("Content-Disposition:filename=".$filename.".xls");
	echo $str;
?>

2.第二种，封装为一个类

<?php

 * @file: cls_output_excl.php

**/
class cls_output_execl {
    public $inEncode; //页面编码
    public $outEncode; //Excel文件的编码

    public function __construct(){
      
    }
    /**
     * @name: set_encode
     * @description: 设置编码

    **/
    public function set_encode($incode,$outcode){
        $this->inEncode=$incode;

        $this->outEncode=$outcode;
    }
    /**

    **/
    public function set_title($titlearr){
        $title="";
        foreach($titlearr as $v){
            if($this->inEncode!=$this->outEncode){
                $title.=iconv($this->inEncode,$this->outEncode,$v)."\t";
            }
            else{
                $title.=$v."\t";
            }
        }
        $title.="\n";
        return $title;
    }

    /**

    **/
    public function set_row($array){
        $content="";
        foreach($array as $k => $v){
            foreach($v as $vs){
                if($this->inEncode!=$this->outEncode){
                    $content.=iconv($this->inEncode,$this->outEncode,$vs)."\t";
                }
                else{
                    $content.=$vs."\t";
                }
            }
            $content.="\n";
        }
        return $content;
    }
    
    /**
     * @name: set_title

    **/    
    public function get_excel($titlearr,$array,$filename=''){
        if($filename==''){
            $filename=date('YmdHis');
        }
        $title=$this->set_title($titlearr);
        $content=$this->set_row($array);
        header("Content-type:application/vnd.ms-excel");
        header("Content-Disposition:filename=".$filename.".xls");
        echo $title;
        echo $content;
        die;
    }
}

调用方法：

//输出到execl
if($output_op == 'output'){ 
    g('output_execl') -> set_encode('utf-8','utf-8'); 
    $title = array('消息序号','商家名称','商铺名称','消息标题','消息发送时间','发送的人数');
    $contentarr = $data['data'];
    if(is_array($contentarr) && count($contentarr)){
        foreach ($contentarr as $key => &$val){
            unset($val['ms_desc']);
            unset($val['ms_issend']);
            unset($val['pus_read']);
            unset($val['bui_call']);
            if($val['ms_send_time']){
                $contentarr[$key]['ms_send_time'] = date('Y-m-d H:i:s',$val['ms_send_time']);
            }
        }
    } 
        
     g('output_execl') -> get_excel($title,$contentarr);
}
