Chapter 13 - Validating Files by Type

Recommended Posts


I am working through Chapter 13 – Validating Files by Type.


I get an error when I try to submit an RTF file (or any file type for that matter) through script 13.3 – upload_rtf.php


Fatal error: Uncaught Error: Call to undefined function finfo_open() in C:\Apache24\htdocs\PHP_and_MySQL\Chapter13\upload_rtf.php:18 Stack trace: #0 {main} thrown in C:\Apache24\htdocs\PHP_and_MySQL\Chapter13\upload_rtf.php on line 18


Line 18 is where the resource is created to check the file type

$fileinfo = finfo_open[FILEINFO_MIME_TYPE];


Running PHP 7.2.1


Is there a setting in php.ini that needs to changed, or can you point me in the right direction?
