Hello,
I was wondering why the exif_read_data function described http://www.manuelphp.com/php/function.exif-read-data.php was not recognized.
Thank you for your help.

P.S.: EXIF data is the metadata generated by digital cameras.
Configuration: Windows XP Internet Explorer 7.0

Hello, what is your version of PHP? In the documentation it says: "(PHP 4 >= 4.2.0, PHP 5)"

phpinfo => version 5.2.-1

Have you ever encountered this function?
If so, can we modify or enter the information attached to the metadata of the jpg file?

I have already used PHP EXIF functions, but it seems to me that they are only for reading.
But there must be writing APIs:

You need to refer to access this file....
Not very encouraging..

You can find elsewhere, but phpclasses.org is a pretty good site for custom classes of this kind.

I thought this function was present in my PHP configuration.
So, I wonder if it's just a PHP extension that needs to be activated.
I don't even know how to do that, if you ask me to use a class!?

I suspect it's a matter of time.
But I would like to know why this reference is not activated?

On the PHP documentation, there is the installation procedure for the basic library:

"Thus, do put exif as the very last extension to load and you should be fine."
It's true that when reinstalling WampServer, you need to remember everything.
Or copy-paste the php.ini.
