How to Extract Text from Word and Office Documents:

Obtaining text from user-uploaded Word documents becomes essential for tasks like keyword searches and data analysis. Here's an efficient solution to extract text from files in various Microsoft Office formats.

DOCX/DOC:

PHP Docx Reader: This library directly converts DOCX files to text without additional dependencies.

XLSX/PPTX:

The provided class extends its functionality to extract text from Excel (XLSX) and PowerPoint (PPTX) files, providing a versatile solution.

Implementation:

1. Create an instance of the DocxConversion class with the file path as an argument.
2. Call the convertToText method to retrieve the extracted text.

Usage:

$docObj = new DocxConversion("test.doc");
//$docObj = new DocxConversion("test.docx");
//$docObj = new DocxConversion("test.xlsx");
//$docObj = new DocxConversion("test.pptx");
$docText = $docObj->convertToText();

Technical Details:

• DOC files: Read using fopen, since they are binary format.
• DOCX files: Treated as zip files containing XML documents, read with zip_open.
• XLSX files: Utilize the XML file "xl/sharedStrings.xml" to extract slide content.
• PPTX files: Scan through the XML files in "ppt/slides" to retrieve text.

Additional Information:
