How to save an image created from imagecreatefromstring() function?

Question

Here is my code:

$data = \'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl\'
       . \'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr\'
       . \'EX4IJT         


        

Answer 1

This is the correct syntax for imagepng:

imagepng($im, "/path/where/you/want/save/the/png.png");

According to the PHP manual:

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

filename - The path to save the file to.

If not set or NULL, the raw image stream will be outputted directly.

Answer 2

Below code will be helpful:

$data = 'code in bytes'; // replace with an image string in bytes
$data = base64_decode($data); // decode an image
$im = imagecreatefromstring($data); // php function to create image from string
// condition check if valid conversion
if ($im !== false) 
{
    // saves an image to specific location
    $resp = imagepng($im, $_SERVER['DOCUMENT_ROOT'].'folder_location/'.date('ymdhis').'.png');
    // frees image from memory
    imagedestroy($im);
}
else 
{
    // show if any error in bytes data for image
    echo 'An error occurred.'; 
}

Please suggest if some other better way of doing !
