[FIXED] How to save an image using PHP and GD

Issue

I am created dynamic image using php and gd library as follows,

imagecopy ($iOut,$imgBuf[0],$left,$top,0,0,imagesx($imgBuf[0]),imagesy($imgBuf[0]));
imagedestroy ($imgBuf[0]);


ob_start();
    imagepng($iOut);
    printf('<img src="data:image/png;base64,%s"/>', base64_encode(ob_get_clean()));

How can I save this image to my local directory for further use. Any help please

Thanks

Solution

Look at the imagepng documentation at http://php.net/manual/en/function.imagepng.php

You can pass in a second parameter to the function as

bool imagepng ( resource $image [, string $filename [, int $quality [, int $filters ]]] )

So you can do

imagepng($iOut, $filename_to_save_to);

then you can simply display the image in the browser as

echo '<img src="' . $public_visible_path_to_saved_file . '"/>';

For this to work, i would choose the $filename_to_save_to as a file in a subdirectory of your web root. E.g.

if your web root is /var/www i would choose /var/www/uploaded_images/filename.png then you can simply display it by specifying the $public_visible_path_to_saved_file as uploaded_images/filename.png
