Problems using in_array() for a processwire array fetched from database

[desbest]

Here is my code.

<?php
$options = $fieldtypes->get('FieldtypeOptions')->getOptions('trader_type'); 
print_r($user->trader_type); echo "<hr>";
if (in_array("1", $user->trader_type)) {
echo "found!";
}
?>

Below is what is printed on the page from the print_r()

ProcessWire\SelectableOptionArray Object ( [count] => 2 [items] => Array ( [1] => 1 [2] => 2 ) )

 

However the in_array() feature does not appear to be working, when I can see from what is on the screen, that it should echo "found!" as the number 1 is in the array as a value.

What is going on and how do I fix it?

You need to get regular PHP arrays (from any WireArray descending object, i.e. all PW collections) using $arr->getArray()

if (in_array("1", $user->trader_type->getArray())) {
    echo "found!";
}

FYI, sometimes it is simpler to do an in-memory search of the WireArray.

E.g. 

$oneItem = $myWireArray->get("id=20");// id is a property in the WireArray
if($oneItem) echo 'we got the item folks!';
$multipleItems = $myWireArray->find("price>500");// price is a property in the WireArray
if($multipleItems->count()) echo 'We got several items';
