【PHPWrod】使用PHPWord导出word文档

目的：PHP通过PHPWord类库导出文件为word。

开发语言及类库：ThinkPHP、PHPWord

一、安装PHPWord类库

项目根目录使用composer安装PHPWord，安装完成后会在vendor目录下生成phpoffice文件夹，就是PHPWord类库

composer require phpoffice/phpword

二、使用PHPWord导出word文件

前端代码

<button type="button" class="layui-btn layui-btn-normal word"><i class="fa fa-file-word-o" aria-hidden="true">i> 导出分析报告 Wordbutton>

// 下载word
	$(".word").click(function () {
		var shijuan_id = GetQueryString('shijuan_id')
		var grade_id = GetQueryString('grade_id')
		$.ajax({
			url:"exportreport2",
			type:'get',
			dataType:'JSON',
			data:{shijuan_id:shijuan_id,grade_id:grade_id},
			success:function (res) {
				console.log(res)
				if (res.code == '200') {
 
					var index = layer.alert('导出成功，请点击下载！', {
					  skin: 'layui-layer-lan' //样式类名
					  ,closeBtn: 0
					  , btn: ['下载'] //按钮
					}, function(){
						var downloadDom = $("");
						// 触发a链接点击事件
						downloadDom.find('span').click();
						setTimeout(function(){ layer.close(index); }, 500);
						
					});
				}else{
					layer.msg('导出失败，请重试~')
				}
			}
		})
	})

PHP代码

use PhpOffice\PhpWord\IOFactory; 
use PhpOffice\PhpWord\PhpWord;
 
public function exportreport2()
{
	$shijuan_id = trim(input('post.shijuan_id'));
	$grade_id = trim(input('post.grade_id'));
 
	try {
		// 班级、试卷信息
		$info = model('Shijuan')->getShijuanGradeInfo($shijuan_id,$grade_id);
 
		// 标题
        $title = $info['filename'].'_考试分析报告';
		// 文件名
        $docxname = $info['grade'].'_'.$info['year'].$info['season'].'_'.$info['filename'].'_考试分析报告'.date('YmdHis',time());
 
		// 分析报告 二维数组
		$list = model('Shijuan')->getStudyReport($shijuan_id,$grade_id);
 
		// 实例化
		$phpWord = new PhpWord();
		header("Content-Type: text/html; charset=UTF-8");
 
		$phpWord->addFontStyle('cStyle', array('size' => 12,'name' => 'msyh'));//内容样式
		$phpWord->addFontStyle('bStyle', array('size' => 12, 'bold' => true, 'name' => 'msyh'));//加粗样式
        $phpWord->addFontStyle('titlestyle', array('bold' => true,'size' => 16,'name' => 'msyh'));//标题的样式
 
        // 创建新页面

        $section->addText('导出时间： '.date('Y-m-d H:i:s',time()), 'cStyle', ['alignment' => 'right']);
 
        // 表格样式
        $styleTable = array( 'borderSize'=>6, 'alignment' => 'center','cellMargin'=>80);
        // 第一行样式
		$styleFirstRow = array('bgColor'=>'f2f2f2' );
    	$phpWord ->addTableStyle('myOwnTableStyle',$styleTable,$styleFirstRow);
 
        foreach($list as $k=>$v) {

            // 添加表格
        	$table = $section->addTable('myOwnTableStyle');
 
			//添加一行（addRow执行后才能使用addCell给本行添加列，括号内数字代表高度）

		// 保存 Word 文档到指定路径
		$savePath1 = '/uploads/docs/'.$docxname.'.docx';
		$savePath = $_SERVER['DOCUMENT_ROOT'].'/uploads/docs/'.$docxname.'.docx';
		$objWriter->save($savePath);

1、前端：先使用按钮事件，在点击事件里去请求后端返回的word文件的地址（这个地址是/uploads/docs/xxx.docx，而不是从系统目录开始）；再使用JQ去触发a链接事件，注意a链接里必须有子元素（这里是span），通过子元素去触发链接

2、后端：上面info、list是从数据库查出来的数据，其中list是要导出的数据，这里是二维数组。先把文件保存到服务器上，再把word地址返回给前端，在前端通过a链接事件去下载导出。由于每导出一个文件都会保留在服务器上一份，长此以往文件会越来越多，所以只保留最近5份，如果文件数量超过5个就全部删除，再执行下载操作。
