Question

好吧，我有一个php类，可以处理word，excel和power point文件，并在加载页面后显示它的数据。它完美地显示word文档数据但是当我使用excel文件 $ docObj = new DocxConversion（“test.xlsx”）; 时它会显示以下错误消息：

我不明白为什么我会得到这些错误消息。有谁能告诉我？

Warning: Missing argument 1 for DocxConversion::xlsx_to_text(), called in D:\Software 
Installed\xampp\htdocs\evan\toplevel\file.php on line 116 and defined in D:\Software

Excel文件数据：

Some text some text 
Some text some text 
Some text some text

Answer 1

这个功能在这里：

function xlsx_to_text($input_file){
    ...
    if(true === $zip_handle->open($input_file)){
        ...
    }else{
        ...
    }
    return $output_text;
}

您在convertToText()功能中调用上述功能如下：

} elseif($file_ext == "xlsx") {
    return $this->xlsx_to_text();
}

您的xlsx_to_text($input_file)函数需要一个参数，但是当您调用它时，您没有传递一个参数。我不会想你上课的方式，你缩进去传递任何参数。我假设您要在初始化时设置$filename属性的对象上调用该函数。因此，我认为您可以按如下方式更新xlsx_to_text($input_file)函数：

function xlsx_to_text(){ // <---------------- Change here.
    ...
    if(true === $zip_handle->open($this->filename)){  // <---------------- Change here.
        ...
    }else{
        ...
    }
    return $output_text;
}

此外，同样适用于您的function pptx_to_text($input_file){功能。
