Re: [PHP] array conversion
Or:
$a = array ('Cats', 'white', 'Dogs', 'black', 'Mice', 'grey', 'Camels',
'brown');
$b = '';// Just in case it has some leftover
value
$k = 2* (int) (count ($a)/2); // ensure even no of terms
$i = 0; while ($i $k)
{
$b[$a[$i++]] = $a[$i++]; // ***
}
And this works:
$i = 0; $k = array_keys($b);
while ($i count($b)) {echo 'h5'.$i.': '.$k[$i].' = '.
$b[$k[$i++]].'/h5'; }
0: Cats = white
1: Dogs = black
2: Mice = grey
3: Camels = brown
( *** I have always been wary of using statements like this because I was
unsure when the
incrementing would occur, so I tried it.)

Thank you in advance.
I don't believe so, but rolling your own should not be too hard:
$a = array($key1, $value1, $key2, $value2);
$b = array();
$numitems = count($a);
for ($i = 0; $i $numitems; $i++) {
if ($i % 2 == 0) {
$saved_key = $a[$i];
}
elseif ($i % 2 == 1) {
$b[$saved_key] = $a[$i];
}
}
Code is crude and untested, but you get the idea.
Paul
This would be even shorter, I think:
foreach ($items as $i = $value) {
$temp[$i % 2][] = $value;
}
$done = array_combine($temp[0], $temp[1]);
(Also untested, just off the cuff...)

$result[] = array($object-name,

}
But why would you want to skip your nicely named, easily readable objects
in favour of sequentially numbered arrays?
Just wondering...
