How can i merge arrays like a gearwheel
- by JuKe
i have 3 arrays like this
$a = array(
0 => 'a1',
1 => 'a2',
2 => 'a3'
);
$b = array(
0 => 'b1',
1 => 'b2',
2 => 'b3'
);
$c = array(
0 => 'c1',
1 => 'c2',
2 => 'c3'
);
and i like to have somethink like this:
$r = array(
0 => 'a1',
1 => 'b1',
2 => 'c1',
3 => 'a2',
4 => 'b2',
5 => 'c2',
6 => 'a3',
....
...
);
how can i do this, with the opinion of more than 3 arrays
EDIT:
i have tried this:
$a = array(
0 => 'a1',
1 => 'a2',
2 => 'a3',
3 => 'a4'
);
$b = array(
0 => 'b1',
1 => 'b2',
2 => 'b3'
);
$c = array(
0 => 'c1',
1 => 'c2',
2 => 'c3',
3 => 'c3',
4 => 'c3',
5 => 'c3'
);
$l['a'] = count($a);
$l['b'] = count($b);
$l['c'] = count($c);
arsort($l);
$largest = key($l);
$result = array();
foreach ($$largest as $key => $value) {
$result[] = $a[$key];
if(array_key_exists($key, $b)) $result[] = $b[$key];
if(array_key_exists($key, $c)) $result[] = $c[$key];
}
print_r($result);
this work.. but the code isn't nice. so anyone has a better solution?
