image not uploading properly when uploading from ios device camera in php - php

Question

I am creating a project in codeigniter in which user can upload his profile image. I am using image library to upload it. When I am uploading image using camera in IOS device, image uploaded with some greyed out area. Code in library is
function createImage($iMageName,$folderName){
$width = 500; $height = true;
$data=base64_decode($iMageName);
$f = finfo_open();
$mime_type = finfo_buffer($f, $data, FILEINFO_MIME_TYPE);
$image = imagecreatefromstring($data);
$height = $height === true ? (ImageSY($image) * $width / ImageSX($image)) : $height;
$output = ImageCreateTrueColor($width, $height);
$imgThumb=uniqid().strtotime(date("Y-m-d H:i:s")).'.jpg';
$imageName=$folderName.$imgThumb;
$fullpath=FCPATH.$imageName;
ImageCopyResampled($output, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
imagejpeg($output, $fullpath, 90);
return $imageName;
}
Working fine for web and android device but problem in ios device, see uploaded image

I have also face the same issue.
Problem will occurs in following condition:
file size. Please validate the file size.
Please write the below code and check that it's working.
function createImage($iMageName,$folderName){
ini_set ('gd.jpeg_ignore_warning', 1);
$width = 500; $height = true;
$data=base64_decode($iMageName);
$f = finfo_open();
$mime_type = finfo_buffer($f, $data, FILEINFO_MIME_TYPE);
$image = #imagecreatefromstring($data);
$height = $height === true ? (ImageSY($image) * $width /
ImageSX($image)) : $height;
$output = #ImageCreateTrueColor($width, $height);
$imgThumb=uniqid().strtotime(date("Y-m-d H:i:s")).'.jpg';
$imageName=$folderName.$imgThumb;
$fullpath=FCPATH.$imageName;
#ImageCopyResampled($output, $image, 0, 0, 0, 0, $width,
$height, ImageSX($image), ImageSY($image));
imagejpeg($output, $fullpath, 90);
return $imageName;
}
