Question

I got an array looking like this:

array("canv" => array(1 => "4", 2 => "6", 3 => "9", 4 => "7");

I need it to look like this:

array("canv" => array("4", "6", "9", "7");

so I can easly check if the value exist this way:

if(isset($result["canv"][$gid])) where $gid is a number from “4”, “6”, “9”, “7”.

How can it be done?

Answer 1

This will flip the values to become keys and vice versa:

$result["canv"] = array_flip($result["canv"]);

So instead of

array(1 => "4", 2 => "6", 3 => "9", 4 => "7")

you’ll have

array("4" => 1, "6" => 2, "9" => 3, "7" => 4)

But then again think about building the original array in the desired way and only do this if you can’t afford that.
