exif - PHP：exif_read_data() not defined

Question

I'm now learning how to extract exif from images.I wrote the simple code like this:

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

But, there is a fatal error about undefined exif_read_data() when running the code. I'm a windows user, and I have modified the php.ini like this :

extension=php_mbstring.dll
extension=php_exif.dll

Thanks for your help.

Answer 1

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

• Have you restarted Apache after editing the php.ini?

• The php.ini you edited is the one used by system? You can verify this reading <?php phpinfo() ?> output.

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