Question

I have worked hard this night to figure out how to split my arrays into a lot of arrays, defined by a value in the array

I could have this value

$array = array ( 
    array ("Apple", 10),
    array("Ball", 5) 
);

Then I want Apple to have 10 arrays where the value is “Apple”, and Ball to have 5 arrays where the value is “Ball”

Then I came up with this, but the output seems pretty strange..

$newarray = array();
foreach($array as $val):
    for($i = 1; $i <= $val[1]; $i++):
        $newarray[$i] = $val[0];
    endfor;
endforeach;

print_r($newarray);
// Array ( [0] => Ball [1] => Ball [2] => Ball [3] => Ball [4] => Ball [5] => Ball [6] => Apple [7] => Apple [8] => Apple [9] => Apple [10] => Apple )

Hope you guys understand my question, and hope some one can figure it out.

In advance, thanks.

array_fill() can help here:

$result = array();

foreach ($array as $sub) {
  $result[] = array_fill(0, $sub[1], $sub[0]);
}

print_r($result);
