Question

I have the following array:

$person = array('first_name' => 'Fred', 'last_name' => 'Flintstone');

I want to change/pad the keys so the array will end up as (note extra colons):

$person = array('::first_name::' => 'Fred', '::last_name::' => 'Flintstone');

For some reason I’m drawing a blank on the simplest way to do this

Answer 1

I don’t know the simplest way, but the quickest way off the top of my head would be to just loop through.

foreach($person as $key=>$value) {
$newArray['::' . $key .'::'] = $value;

}

I guess you could even do

function tokenize($person)
{
    foreach($person as $key=>$value) {
    $newArray['::' . $key .'::'] = $value;    
    }
    return $newArray;
}

$person = array('first_name' => 'Fred', 'last_name' ='Flintstone');
$newPerson = array_map("tokenize", $person);
print_r($newPerson);
