Change $key of associative array in a foreach loop in php

Question

I have an array like this:

array(
    \'firstName\' => \'Joe\',
    \'lastName\'  => \'Smith\'
    )

I need to loop over every elemen

Answer 1

Top of my head...

foreach($array as $key => $value){
    $newKey = ucfirst($key);
    $array[$newKey] = $value;
    unset($array[$key]);
}

Slightly change your way of thinking. Instead of modifying an existing element, create a new one, and remove the old one.
