⑴ php怎麼讀取ppt文字內容並在瀏覽器中顯示出來
具體代碼麻煩我就不寫了，可以提供給你一個思路：
首先要求伺服器上安裝wps或者microsoft powerpoint軟體，然後通過api介面來訪問並讀取ppt，最後將其發送到頁面。
當然你不能每次等別人訪問的時候再去讀取，不然太慢。。這個辦法比較簡便，如果你想直接讀取，則需要詳細了解ppt文件的格式。
⑵ 為什麼ipad上下載的ppt打開變成PHP
如果不是下載本身資源的錯誤，把後綴php修改成PPT
如果你下載時沒下載對，那麼需要重下；如果僅僅是文件的擴展名錯了，那麼你可以將php改為ppt，需要設置文件宏激夾選項顯示文件的擴展名才可以。
pdf全稱是Portable Document File，PPT全稱是PowerPoint，PPT 是與文檔(Word)，表格(Excel)並列的一蔽虛襪種演示文稿，PDF 則是PDF文件。PPT文件的後綴名譽激為:.ppt或.pptx;而PDF文件的後綴名為.pdf。
⑶ 怎麼用php讀取ppt文檔的內容，並且在瀏覽器
本文實例講述了PHP讀取PPT文件的方法。分享給大家供大家參考，具體如下：
最近做一個和FLASH有關的東西，其中就要用到在網站上看PPT就像網路，豆丁網那樣可以直接在網站上讀，在網上搜了半天沒搜到，都是些什麼安裝個軟體什麼的，PHP網站放到空間上，誰能讓你在哪裝軟體呢？不是在瞎扯么？不過還好，最後在國外一個網站上搜到了一個解決思路，就是一個PHP操作PPT的類，當然這個網站還提供了操作OFFICES軟體的其他類，不過是2007版的OFFICES
下面也貼出當時看到的一個例子:
本例子使用phppowerpoint類，使用該類注意兩點，一個是了解參數含義，二注意字元集
