Compare arrays

[Anon]

Hi,

I have two arrays

$one = array ( "1" => 0, "2" => 0, "3" => 0, "4" => 0, "5" => 0 );

$two = array ( "1" => 2, "2" => 5 );

as you can see the first has all zeros for values.

The values in the second array represent the keys in the first. I know this is not very clear so :

I need to read the values from the second array and then replace the values of the first with the integer 1 if they are in the second array.

So the resulting array would look like this

$three = array ( "1" => 0, "2" => 1, "3" => 0, "4" => 0, "5" => 1 );

Can anyone please help me with this?

Many Thanks in advance

for ($t=1;$t<=count($two);$t++)
{
$one[$two[$t]]=1;
};

you could also use array_merge, but that has "weird" behaviour when identical keys have identical values in both arrays.
