I'm no expert (see my own question!) but I think you would do this as:

for($i=0;$i<20; $i++) {

array_merge($ar r, array($i => $i+1)}

}

In other words you merge your existing array with a new one consisting
of the new key=>value mapping that you want to add.

Or at least that's how I've done it before...

Not really sure what mean. Could you explain or post an example of what
$arr should look like after the above loop?


I would simply interpret your code as

$arr = array();
for ($i = 0; $i < 20; $i++) {
$arr[] = array($i => $i+1);
}

but that's probably not what you wanna do.
