使用PHPOffice/PHPPresentation生成超大PPT文件

估计一般大家也用不到这个方式，必定需要生成几个G甚至几十G的PPT用途也不大，但生产环境有时候真的需要。下面就简单介绍分批生成单个超大PPT的方式。
原理：Office家族 Excel,PowerPoint都是压缩文件，将文件名后缀修改为.zip就会发现原来他们都是压缩包，针对里面的关联文件做修改便可以实现追加或者删除操作，是不是被惊到了呢？！这可是我研究了好多方式才发现的哦。
因为代码太据针对性，不是通用的，这里只列举一些通用的东西。
先说保存之前，所需数据都是差不多的， 首先需要一个封装好的类 PowerPoint.php 这里面封装通用的方法
调用时候代码说明（以CI（CodeIgniter）为例）
require_once APPPATH . 'third_party' . DIRECTORY_SEPARATOR . 'PHPOffice' . DIRECTORY_SEPARATOR . 'PowerPoint.php';
//创建类
$powerPoint = new PowerPoint();
//第一次生成的时候加上文档信息把，追加PPT的时候就不需要了
$powerPoint->getDocumentProperties()->setCreater('CX')->setCompany('Focusmedia')->setTitle('PPT属性里面的标题')->setDescription('PPT属性里面的描述')->setCategory('PPT')->setLastModifiedBy('System');
//无论首次还是追加都需要设置母版
$powerPoint->createMaster();
//第一次的时候可能需要单独的一个头部信息
$powerPoint->createHeader($dataHeader);
//循环调用此方法，每调用一次增加一个PPT页面
$powerPoint->createCotent($data);
//判断所有PPT页面都加完了调用此方法
$powerPoint->createFooter();
//保存或者追加用此方法，里面判断不存在文件时用自带的save方法，否则追加，追加方法看后面
$powerPoint->appendSave($file);
下面举例调用方式，比如你上万条记录需要生成PPT，我们要分批追加，这样才不会导致内存溢出而无法正常使用。
可以先将数据整理成二维数组，每组为1个页面，看实际情况
$list_page = array();
foreach ($list as $key => $item) {
$list_page[$item['page_number']][] = $item;
}
$per_group = 100;//每生成100页PPT保存1次
$group_page = ceil( count($list_page) / $per_group);//总数据分的页数
//引入类
require_once APPPATH . 'third_party' . DIRECTORY_SEPARATOR . 'PHPOffice' . DIRECTORY_SEPARATOR . 'PowerPoint.php';
$tmp_file_path = '要保存的文件名.pptx'
for( $i = 1; $i <= $group_page; $i++) {
$powerPoint = new PowerPoint();//每批都需要重新创建此类
$powerPoint->createMaster();//每批都需要设置母版
//这里每批要处理的循环
for($key = ($i-1) * $per_group + 1; $key <= $i * $per_group AND $key <= count($list_page); $key++ ) {
if($key == 1) { //第一条记录为头部
$powerPoint->getDocumentProperties()->setCreater('System Report monitor')->setCompany('Focusmedia')
->setTitle($report['contract_no'] . '_' . $report['city_name'].'_'.$report['publish_date'])
->setDescription($report['contract_no'] . '_' . $report['city_name'].'_'.$report['publish_date'] . '_' . ($report['export_war'] == 2 ? $report['design_no_str'] : $report['export_war']))
->setCategory($report['contract_no'])->setLastModifiedBy('System');
//创建第一页，因为第一页可能和后面的内容不同;
$powerPoint->createHeader($list_page[$key][0]);
} else {
$powerPoint->createContent($list_page[$key]);
}
if($key == count($list_page)) {
//创建完所有数据是不是应该还有个结束页，谢谢大家观赏
$powerPoint->createFooter($type);
}
if($key == $i * $per_group || $key == count($list_page)) {
//******此次循环结束或数据结束，保存PPT
$powerPoint->appendSave($tmp_file_path);
$powerPoint = null;
}
}
}
//循环执行完，就得到想要的文件了，
以下重点介绍PowerPoint.php的内容，尤其是appendSave()方法，是整个操作的核心

重点：把PPTX文件看作一个压缩文件，读取压缩包中特定文件或添加特定文件，这样可以保证不把所有的内容全部加载到内存。 其实里面占比例最大的是图片，所以这里我们按每次100张幻灯片来处理，请根据实际情况分配批次。
难点：如何将已经存入到PhpPresentation中的内容写入到已存在的文件中，这里需要我们将PPTX文件中的子文件都了解清楚，以及研读系统中save的实现方式，将我们需要的内容单独处理掉。
