stop repetition of data displayed, foreach loop php, mysql

Question

I have a code which gives me list of addresses in my view file but some addresses are repeated. I don't want to display the ones which are already displayed.

$address_array[] = '-- Select address --';

foreach($address as $addres){
    $address_array[$addres->id] = $addres->town;
}

Any idea on stopping the repetition?

With the in_array function, you can check if a value already exists in your array

$address_array[] = '-- Select address --';

foreach($address as $addres){
    if (!in_array($addres->town, $address_array)) $address_array[$addres->id] = $addres->town;
}

Use array_unique to erase duplicates.

A little example :

$address = array_unique($address);
