Phppowerpoint 获取文本

Phppowerpoint in getting text

PhpPowerpoint 是否能够从现有的 pptx 中获取文本? 因为我想从现有的 pptx 中获取文本到 php。有没有可能实现?

是的,是的。

PhpPresentation,旧称 PHPPowerPoint,有一些读者:PowerPoint2007、PowerPoint97 和 ODPresentation。这些阅读器允许提取具有内容和格式的形状。

这是程序,甚至可以处理 unicode 字符。 它将 LF 转换为 CRLF 中的 pptx 文本以供阅读。 完成后(另存为 AllUniB)用 Word 打开它,转换 Unicode,清理多个段落(将 ^l 替换为 ^p,然后将 ^p^p 替换为 ^p) 你准备好了。

要转换,请将此代码添加到 pptx 宏并 运行 它:

  Dim oSlides As Slides
  Dim oSld As Slide         'Slide Object
  Dim oShp As Shape         'Shape Object

  iFile = FreeFile          'Get a free file number
