How to pass image data from base64 src attribute via AJAX and receive it in PHP using imagecreatefromstring? If I just pass it as a regular variable, php gives out invalid data in imagecreatefromstring

var data64 = canvasImg.toDataURL("image/jpeg");
      
      $.post("/ajax", { base64: data64},
          function(data){
            alert(data);
          });

Answer 1

imagecreatefromstring(base64_decode($string))
