array to string (php)

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.

You would surely get _some result_ but it looks like [you are converting a 2 dimensional array to a string](http://stackoverflow.com/search?q=%5Bphp%5D+implode+multi+dimensional). As Tim asked, what should the output look like? — Michael Berkowski, Nov 04 '12 at 12:31
@VolodyaDaniliv Do you want an _array_ of strings red,green,blue,alpha? — Michael Berkowski, Nov 04 '12 at 12:33
yes, i need one string like this: 255.255.255.127,255.255.255.123,... — Bob Dylan, Nov 04 '12 at 12:35

Array:

$pxlCorArr = 
  array(
      array (
           array('red' => 255, 
                 'green' => 255,
                 'blue' => 255,
                 'alpha' => 127
           ),

           array('red' => 255,
                 'green' => 255,
                 'blue' => 255,
                 'alpha' => 127
           )
      )
  );

Code:

$output = '';
foreach ($pxlCorArr as $subArray) {
    if(is_array($subArray)) {
        foreach ($subArray as $subArray2) {
            if(is_array($subArray2)) {
                $output .= implode ('.', $subArray);
                $output .= ',';
            }
        }
    }
}
$output = rtrim($output, ',');

Output:

255.255.255.127,255.255.255.127

`implode()` would be less expensive, instead of the whole concatenation and trimming ;-) – Havelock Nov 04 '12 at 12:43
tell me please where i need to insert input array – Bob Dylan Nov 04 '12 at 13:06
just change $array to the name of your array, which I guess is $pxlCorArr, right? – Tivie Nov 04 '12 at 13:11
thx! but result is: Array.Array.Array.Array.Array.Array.Array.Array.Array. – Bob Dylan Nov 04 '12 at 13:15
can you help me to fix this trouble? – Bob Dylan Nov 04 '12 at 13:23
It was at title of example, but you're right yes... Lemme correct the answer – Tivie Nov 04 '12 at 13:27

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

                )
             ...

        )

)


$string = '';
$array = $exists_array[0];
foreach ($array as $key => $value) {
$string .= $key." : ".$value."\n";
}
print $string;

Using array_walk over lambda function:

  $implodevals =  create_function('&$val', '$val = implode(".", $val);');
  array_walk($array, $implodevals);
  print rtrim(implode(", ", $array), ",");

Input array:

   $array = Array
    (
        0 => Array
            (
                "red" => 255,
                "green" => 255,
                "blue" => 255,
                "alpha" => 127
            ),

        1 => Array
            (
                "red" => 255,
                "green" => 255,
                "blue" => 255,
                "alpha" => 127,
            )



     );
