Laravel match string to array

Question

I am trying to match values from a user's input ($index) to an existing array ($ppeWorn). A user can select more than one option. When I try to find out if there are keys of the user's input that match the $ppeWorn array, I get only the first item selected.

The value of dd($indexArray) is:

array:2 [
  0 => "1"
  1 => "2"
]

My code is as follows:

case 7:
                        $index = ($parts[6]) ;

                        $ppeWorn = [
                            'None',
                            'Gloves',
                            'Fabric mask',
                            'Surgical/Medical mask',
                            'N95 mask (or equivalent)',
                            'Face shield or goggles/protective glasses',
                            'Disposable gown',
                            'Waterproof apron',
                        ];

                        $indexArray = explode(',', $index ) ;
                        dd($indexArray); 
                                                              
                            foreach($indexArray as $value) {

                                if ($ppeWorn[$value]) {

                                    $session["ppes"] = $ppeWorn[$value];
        
                                    $this->setSession($session);
        
                                    dd($session);
        
                                    $response = $this->sessionOpeningTag . "Have you received IPC training?\n1. Yes\n2. No";
                                
                                } else {

                                    $response = $this->sessionClosingTag . "You have entered an invalid answer";
        
                                    $this->deleteSession($session);
        
                                }  
                                 
                            }
                        
                        break;

You need to go get some advice on codereview.stackexchange.com this code is not good - your data structure are particularly inappropriate. — symcbean

So your $input is an array, but it's first element is "1,2". So as my understanding of your question and code (please update the code, provide only useful stuffs), you want to iterate over $index and match the values with switch-case.

To do this you may try:

$indexArray = explode(',', $index[0]; // cause $index[0] has a string which has 
                                      // some comma separated value

foreach($indexArray as $value) {
    ... ... ...
    // Do your stuffs here

}

You can check exists values from a users input($index) to an existing array($ppeWorn). By using this way ___

$checkValue = array_key_exists($users_input,$ppeWorn);
echo $checkValue;

returns true if the key exists in $ppeWorn;
