为什么在这个函数之后没有执行file_put_contents（）代码行？

Question

i have created one function to upload image using web services.

$image_url=time().$img_name;
$path=$_SERVER['DOCUMENT_ROOT'].'/img';
$image_url_src=$path."/".$image_url;
$current = file_get_contents($image_url_src);
$current = base64_decode($img_url);
            
$res=file_put_contents($image_url_src,$current);
chmod($image_url_src, 0777);
if($res===true)
{
  $folder_img_url1="http://www.example.com/img/".$image_url;
  $auth_error=array("img_url"   => $folder_img_url1); 
  return json_encode($auth_error);
}

Everything is working properly.. only problem is why not returning value after this line of code file_put_contents($image_url_src,$current);

if i return any value before file_put_contents function than it works but after calling file_put_contents() after that not return works so why?

ANY HELP WOULD BE APPRECIATED

This Code is works for me...

$image_url=time().$img_name;
$path=$_SERVER['DOCUMENT_ROOT'].'/img';
$image_url_src=$path."/".$image_url;
//$current = file_get_contents($image_url_src); //this line of code is no need because of this not returning value..because it gives me an error.
$current = base64_decode($img_url);
$res=file_put_contents($image_url_src,$current);
//chmod($image_url_src, 0777);  if will remove than also its works
if($res===true)
{
  $folder_img_url1="http://www.example.com/img/".$image_url;
  $auth_error=array("img_url"   => $folder_img_url1); 
  return json_encode($auth_error);
}

Thank you for your time..
