Extract Data from PDF form Undefined Functions

[dman271828]

Overall this is the best PdfToText php code I have found. Great code and good job. There are two errors inside the PdfToText.phpclass when I ran the extract form data from pdf example.

Example:
/PdfToText-master/examples/formdata-extraction/example.php

Error 1:
Undefined function ValidPhpName....

My solution:
The ValidPhpName should be member of PdfObjectBase::. However, everywhere in the program it refers to an incorrect class.

Replace all:
PdfToTextFormDefinition::ValidPhpName

With:
PdfObjectBase::ValidPhpName

Error 2:
The GetFormDataFromPdfObject is private error.
Old:
private function GetFormDataFromPdfObject ( $pdf_data )

Change it to pubic.
public function GetFormDataFromPdfObject ( $pdf_data )

This solution worked for me. Here is a portion of the form data output.

OUTPUT:
