2. exif_read_data — Reads the EXIF headers from an image file. It is an Exif function that depends on the Exif extension. Checking phpinfo, the Exif extension is not installed. See Figure 2.
3. The local environment is Windows 10. Checking the extensions directory: C:\php-7.4.6\ext, the file php_exif.dll exists. See Figure 3.
4. Edit the php.ini file. Remove the ; from ;extension=exif.
Before modification:
INI
;extension=exif ; Must be after mbstring as it depends on it
After modification:
INI
extension=exif ; Must be after mbstring as it depends on it
5. Check phpinfo. The Exif extension is now installed. See Figure 4.
6. Upload the image again; no error occurs. See Figure 5.
