In cases the file is yet to be identified, the method IOFactory::identify() can be used to automatically identify a file type. The file type is needed to instantiate the reader object.
Requirements:
- Composer
- PHP 7.2 or newer
Step 1.
Setup dependencies.
{
"require": {
"phpoffice/phpspreadsheet": "^1.3"
}
}Step 2.
Install phpspreadsheet.
$ composer install
Step 3.
Create a new PHP file, and start coding.
<?php // Autoload dependencies require 'vendor/autoload.php'; // Import the IOFactory class use \PhpOffice\PhpSpreadsheet\IOFactory; // Full path of the file to be indentified $inputFileName = 'create-xlsx-files.xlsx'; // Identify the file type using the IOFactory object $inputFileType = IOFactory::identify($inputFileName); // Display the file type echo $inputFileType;
Test.
Command line testing.
$ php identify-file-types.php
Result.
