Question

I am building a function which I want to retrieve key/value pairs from db, and it comes like $result=array($key=>$value); and when I use this $result, in an object requiring an array in its parameters

function Foo($result) { array ('superkey'=>$result); }

this considers that $result contains multiple arrays like this:

Array
(
    [key1] => value1
)
Array
(
    [key3] => value2
)
Array
(
    [key3] => value3
)
Array
(
    [key4] => value4
)

But I want it to consider it as one array:

Array
(
    [key1] => value1

    [key3] => value2

    [key3] => value3

    [key4] => value4
)

Can any one help me out?

Answer 1

When you retrieve values from a database, it usually sends a multi-dimensional array like:

array(3) {
  [0]=> array(1) { ["samekey"]=> value1 }
  [1]=> array(1) { ["samekey"]=> value2 }
  [2]=> array(1) { ["samekey"]=> value3 }
}

The keys of these arrays are always the same, because they represent the column name from the database. It sounds to me like you’re looking for a way to compile all those values into a single array. To do that, you need to forget about the key, and use something ike this:

foreach($result as $entry) $fixedresult[] = $entry['samekey'];
