array

[saku]

i have an array:
$arr = array('a' => 'letter a', 'b' => 'letter b', 'c' => 'letter c');

how do i create a new array, that is the copy of $arr, but have all values equal '' (or 0 - doesnt matter)

i do it by copying and then applying array_walk, but there must some simple solution

function duplicateEmptyArray( $yourArray ){
if (is_array( $yourArray )) {
foreach( $yourArray as $key => $value){
$newArray[ $key ] = "";
}
} else {
$newArray = array('0' => 'ERROR!!!');
}
return $newArray;
}

$arr = array('a' => 'letter a', 'b' => 'letter b', 'c' => 'letter c'); 
$arr2 = duplicateEmptyArray( $arr );

or something (didn't test it, you do it 🙂)
