malformed utf-8 characters possibly incorrectly encoded - php

Question

I have encoded image to base64 in iOS and sending it to server and then using base64_decode() on that string. But it is giving an error
malformed utf-8 characters possibly incorrectly encoded
i am doing this in laravel and using php core function;
public function createIdea(Request $request) {
$filename = str_random(8);
$imageStr = $request->input('idea_image');
$decodeImage = base64_decode($imageStr);
$image = imagecreatefromstring($decodeImage);
if ($request->hasFile($image)) {
$filename = $request->file($image)->getClientOriginalName();
$moveImage = $request->file($image)->move('images', $filename);
}
$idea = new Idea();
$idea->idea_title = $request->input('idea_title');
$idea->idea_info = $request->input('idea_info');
$idea->idea_image = "images/".$filename;
$idea->idea_location = $request->input('idea_location');
$idea->idea_description = $request->input('idea_description');
$idea->idea_description = $request->input('selection');
$idea->user_id = \Auth::id();
$idea->save();
$ideaId = $idea->id;
if ( ! $idea->id ) {
$statusCode =404;
response()->json(array('Status:' => 'Idea Creation FAILED'),$statusCode);
}else{
$response = $idea->toJson();
$statusCode =200;
return response()->json(array('Status:' => 'Idea Created Successfully', 'ideaId' => $ideaId, 'image' => $imageStr),$statusCode);
}
Any help would be appreciated.

Encoding the blob in base64 before serving the data in any language will allow you to transfer BLOB data as safe strings!
