Question

I have a variable that contains text with values according to an example below:

$data = "5:7|4:1|504:2|1:3|"

And I would like to achieve results like this:

$data[5] = 7;
$data[4] = 1;
$data[504] = 2;
$data[1] = 3;

I tried with explode:

$data = explode("|", $data);

//but it makes $data[0]="5:7"; $data[1]="4:1"; and so on.

Should I use explode again? Is it has any sense, or is there another way? I would like to ask for a hint or help.

Answer 1

There may be a more clever way, but I’d do it like this:

$data = array();
foreach (explode("|", $your_data) as $part)
{
    $pieces = explode(':', $part);
    // Assumes we have 2 pieces, might want to make sure here...

    $data[$pieces[0]] = $pieces[1];
}

Also, I’m not sure what this data represents but keep in mind that array keys will overwrite each other, so 1:1|1:2 will result in an array with only one item (the last piece). There may be good reason to take another approach.
