PHP: exif_read_data () not defined

Question

Now I am learning how to extract exif from images.I wrote simple code as follows:

<?php
//Get the exif data
$exif_data = exif_read_data('sample.jpg');
print_r($exif_data);
?>

But when executing the code, a fatal error occurs regarding undefined exif_read_data (). I am a Windows user and I changed php.ini as follows:

extension=php_mbstring.dll
extension=php_exif.dll

Thank you for your help.

Answer 1

• Do you have these DLLs on your system in a folder Php/ext?

• Did you restart Apache after editing php.ini?

• Have you edited the php.inione used by the system? You can check this indication <?php phpinfo() ?>.

• Is there any <?php phpinfo() ?>information about the EXIF ​​extension in the output?
