How can one properly fill an associative array in PHP using a foreach loop?

When filling an associative array in PHP using a foreach loop, you can iterate over another array and assign key-value pairs to the associative array. This can be done by looping through the original array and using each element to set a key and value in the associative array. 

$originalArray = array("key1" => "value1", "key2" => "value2", "key3" => "value3");
$associativeArray = array();

foreach($originalArray as $key => $value){
    $associativeArray[$key] = $value;
}

print_r($associativeArray);
