⑴ php怎么读取ppt文字内容并在浏览器中显示出来
具体代码麻烦我就不写了，可以提供给你一个思路：
首先要求服务器上安装wps或者microsoft powerpoint软件，然后通过api接口来访问并读取ppt，最后将其发送到页面。
当然你不能每次等别人访问的时候再去读取，不然太慢。。这个办法比较简便，如果你想直接读取，则需要详细了解ppt文件的格式。
⑵ 为什么ipad上下载的ppt打开变成PHP
如果不是下载本身资源的错误，把后缀php修改成PPT
如果你下载时没下载对，那么需要重下；如果仅仅是文件的扩展名错了，那么你可以将php改为ppt，需要设置文件宏激夹选项显示文件的扩展名才可以。
pdf全称是Portable Document File，PPT全称是PowerPoint，PPT 是与文档(Word)，表格(Excel)并列的一蔽虚袜种演示文稿，PDF 则是PDF文件。PPT文件的后缀名誉激为:.ppt或.pptx;而PDF文件的后缀名为.pdf。
⑶ 怎么用php读取ppt文档的内容，并且在浏览器
本文实例讲述了PHP读取PPT文件的方法。分享给大家供大家参考，具体如下：
最近做一个和FLASH有关的东西，其中就要用到在网站上看PPT就像网络，豆丁网那样可以直接在网站上读，在网上搜了半天没搜到，都是些什么安装个软件什么的，PHP网站放到空间上，谁能让你在哪装软件呢？不是在瞎扯么？不过还好，最后在国外一个网站上搜到了一个解决思路，就是一个PHP操作PPT的类，当然这个网站还提供了操作OFFICES软件的其他类，不过是2007版的OFFICES
下面也贴出当时看到的一个例子:
本例子使用phppowerpoint类，使用该类注意两点，一个是了解参数含义，二注意字符集
