The string of

PHP is binary safe, and the binary data can be saved directly into the string.

Functions such as imagepng and imagejpeg of

ob_start();   //
imagepng($image);    //
$imagebin=ob_get_contents();    //
ob_end_clean();    //

The content in

$imagebin is the same as the binary data that is saved to a file and read with file_get_contents .
