使用cordova将base64字符串保存为php中的图像

  • cordova
  • php

I am trying to save the captured image in my server as jpg/png,I decoded the string as base64 and uploaded it but when i open the image it says 'the file cant open'. I don't understand why this is happening or i just missed any code.

jquery

navigator.camera.getPicture(onSuccess, onFail, { quality: 100,destinationType: Camera.DestinationType.DATA_URL });

function onSuccess(imageURI) {
 var image = document.getElementById('dr_preview');
 image.src = imageURI;
 snapSrc = imageURI;
}
var img = document.getElementById('dr_preview');
var src = $('#dr_preview').attr('src');
console.log(src);
var dataparam = 'type=3&dr='+dr_value+'&image='+src;
$.ajax({
        type: 'POST',
        dataType: 'json',
        async: true,
        url: 'http://localhost/v_2/dr-getDrDetails.php',
        data: dataparam,
        cache: true,
        success: function(data)
        {
        }
 });

php

$data = $_POST['image'];
$data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data));
$filePath = $_SERVER['DOCUMENT_ROOT']. '/v_2/scanedDR/'.$dr.'.PNG';
$file = fopen($filePath, 'w');
fwrite($file, $data);
fclose($file);
