Question

I have an array in the format

Array
(
    [/Callum/] => Array
        (
            [0] => ##chan1
        )
    [/Adam/] => Array
        (
            [0] => ##chan2
        )   
    [/Chris)/] => Array
        (
            [0] => ##chan1
        )
    [/Mike*/] => Array
        (
            [0] => ##chan3
        )
)

And from this I use the below code to try and get the id of the array that each channel features in.

foreach($array as $row)
{

    if (in_array($buf['channel'],$row))
    {
        $return = $return." ".current(array_keys($array,$row));
    }
}

My problem is that current() doesnt seem to work the way I am expecting it to. Currently if the $buf /Callum/ twice rather than /Callum/ and /Chris/

Answer 1

Why not:

foreach($array as $key => $row)
{

    if (in_array($buf['channel'],$row))
    {
        $return = $return . " " . $key;
    }
}
