PHP echo array value without looping

Question

I have the following code which works perfectly fine to give me the name of the customer with the ID of 10:

foreach($customer_list as $row) {
    if ($row->CUSTOMER_ID == 10)
    echo $row->NAME;
}

Is there a way I can do this more directly, without the foreach loop and if statement? I'd like to do something like:

echo $customer_list[CUSTOMER_ID][10]->NAME;

But I don't know the syntax or if it's even possible.

Where did you get the $customer_list variable? Database call? — user5051310

You could use array_filter It will return an array of customers whose ID is 10. We then select the first match (the only match probably) and access the NAME property.

$name = reset( array_filter(
            $customer_list,function($c){return $c->CUSTOMER_ID === 10;}
    ))->NAME;

The cleaner approach is to factor it out, into a separate function:

$getCustName = function($list,$id){
    return reset( array_filter(
        $list,
        function($c) use ($id) {return $c->CUSTOMER_ID === $id;}
    ))->NAME;
};

Then you can get the name easily with just one line:

$name = $getCustName($customer_list,10);

You can use php array_filter method. Basically you need to pass a function which will check value of customer_Id and returns the element of the array.

you can add your code inside a function and then call that function when you need the name. I am assuming you have unique customer ID's.

function getCustName($customers,$id){
  if(count($customers)>0){
    foreach($customers as $row) {
       if ($row->CUSTOMER_ID == $id)
       return $row->NAME;
    }
  } else{
      return false;
  } 
}

Now if you need to get customer name just call the function

echo getCustName($customer_list,10);
