how to create a base64encoded string from image resource

Question

I have sent a base64 encoded string via AJAX to PHP and created an image resource with imagecreatefromstring - all is fine.

Now I want to get the base64 encoded string after resizing te image, but i CANT find a function to get the base64encoded string.

@mishu of course... i tried base64encode($imageres) and even ob_contents etc. but it doesnt work... – Uwton

You can use resample to get the base64 encoded string after resizing – Troublemaker

Taken from http://www.php.net/manual/en/book.image.php#93393

$image = imagecreatefromstring($file);

// start buffering
ob_start();
imagepng($image);
$contents =  ob_get_clean();

echo "<img src='data:image/png;base64,".base64_encode($contents)."' />";

imagedestroy($image);

Hmm, I'm sure i tried this before! Now it works. Thank you very much. – Uwton

@netzafin: I know that feeling ;) – Infliction

According to the manual $contents = ob_get_clean(); is a one-liner for what ob_get_contents and ob_end_clean does. – Messenia
