Question

Please help me to convert array to string.

array look like this:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [red] => 255
                    [green] => 255
                    [blue] => 255
                    [alpha] => 127
                )

            [1] => Array
                (
                    [red] => 255
                    [green] => 255
                    [blue] => 255
                    [alpha] => 127
                )
             ...

        )

)

I tried to use the implode function, but no result…

$string = implode(", ", $pxlCorArr);

PS: Sorry for my english i from ukraine.

Answer 1

That would be another possibility, as a function to which you pass your initial array and the function returns the string you needed:

function getRGBAlpha($pxlCorArr) {

    $rgbVals = array();
    foreach($pxlCorArr as $subArr) {
        if(is_array($subArr)) {
            foreach($subArr as $colValues) {
                $rgbVals[] = implode('.', $colValues);
            }
        }
    }

    return implode(',', $rgbVals);
}

and so you could do the following, somewhere in your code, to get the output you needed:

echo getRGBAlpha($pxlCorArr);

should output:

255.255.255.127,255.255.255.127
