if multiple variables are empTY - php

Question

I am trying to check to see if any of the fields have been field out and if NONE have been field out return back to page with error. Even if I have a field filled it still returns acting like no fields are selected.
Controller
public function getServices() {
$user = User::find(Auth::user()->id);
$input = [
'rooms' => Input::get('rooms'),
'pr_deodorizer' => Input::get('pr_deodorizer'),
'pr_protectant' => Input::get('pr_protectant'),
'pr_sanitizer' => Input::get('pr_sanitizer'),
'fr_couch' => Input::get('fr_couch'),
'fr_chair' => Input::get('fr_chair'),
'pr_sectional' => Input::get('pr_sectional'),
'pr_ottoman' => Input::get('pr_ottoman'),
'pr_tile' => Input::get('pr_tile'),
'pr_hardwood' => Input::get('pr_hardwood')
];
$empty = 'No services were selected';
$var = $input['rooms']&& $input['pr_deodorizer']&&
$input['pr_protectant']&& $input['pr_sanitizer']&&
$input['fr_couch']&& $input['fr_chair']&&
$input['pr_sectional']&& $input['pr_ottoman']&&
$input['pr_tiles']&& $input['pr_hardwood'];
if(empty($var)){
return Redirect::to('book/services')->withErrors($empty)->withInput();
}
foreach($input as $services)
{
$service = new Service();
$service->userID = $user->id;
$service->services = $services;
$service->save();
}
return Redirect::to('book/schedule');
}
I have tried !isset() but I still cannot get it to work.

if you want to check if variable is empty, you should use empty() function not &&
when you using && string "0" is casted to false, this may be not what you expecting.
if you want to detect if any of keys in array is empty use this function:
function arrayEmpty($keys, $array) {
$keys = explode(" ", trim($keys));
foreach($keys as $key) {
if (!isset($array[$key]) || empty($array[$key])) return true; // isset prevents notice when $key not exists
}
return false;
}
use example:
$array = array( "foo" => "bar" );
arrayEmpty("foo", $array); // false
arrayEmpty("foo bar", $array); // $array["bar"] not exists, returns true
