$file_name=$_FILES["file"]["name"];
$temp_name=$_FILES["file"]["tmp_name"];
$imgtype=$_FILES["file"]["type"];
$ext= GetImageExtension($imgtype);
$imagename=date("m-Y")."-".rand().$_FILES['file']['name'];
$target_path ='images/'.$imagename;
if(move_uploaded_file($temp_name, $target_path)) {
$result = $url.'api/'.$target_path;
$json = array( "status" =>1,"file-url" => $result, "files" => $_FILES);
}else{
if ($_FILES['uploaded']['error'] !== UPLOAD_ERR_OK) {
$json = array( "status" =>0, "error" => $_FILES['uploaded']);
}
else{
$json = array( "status" =>0,"files" => $_FILES);
}
}
