好吧，我有一个php类，它处理word、excel和powerpoint文件，并在加载页面后显示其数据。它完美地显示了word文档数据，但当我使用excel文件时$docObj=new DocxConversion（"test.xlsx"）然后它向我显示以下错误消息：
我不明白为什么我会收到这些错误信息。有人能告诉我吗？

Excel文件数据：
Some text some text
Some text some text
Some text some text
这里是这个函数：
function xlsx_to_text($input_file){
...
if(true === $zip_handle->open($input_file)){
...
}else{
...
}
return $output_text;
}
您在convertToText()函数中调用上述函数如下：
} elseif($file_ext == "xlsx") {
return $this->xlsx_to_text();
}
你的xlsx_to_text($input_file)函数需要一个参数，但你在调用它时没有传递一个。我不认为你写类的方式是缩进来传递任何参数。我假设您想在初始化时设置$filename属性的对象上调用该函数。所以，我认为你可以更新你的xlsx_to_text($input_file)功能如下：
function xlsx_to_text(){ // <---------------- Change here.
...
if(true === $zip_handle->open($this->filename)){ // <---------------- Change here.
...
}else{
...
}
return $output_text;
}
同样，function pptx_to_text($input_file){函数也是如此。
