Join 2 array

[Son Nguyen]

Hi,

I know ways to join the arrays, but pretty ugly, prefer an optimized function of PHP. So the question is:

Is there a function for joining 2 array? and is it in PHP4 or PHP3?

Thanks

Son

array_merge() is what you are looking for I believe. Its a PHP4 function

[Son Nguyen]

I'm currently on a PHP3 server, so any function like array_xx is unsupported!!! Thanks Freddy, have to ask for PHP4 now

There is of course the long way to do it

for($i=0;$i<count($array2);$i++) {
$array1[count($array1)] = $array2[$i];
}

Freddy, is there a reason why you use:
'$array1[count($array1)]'?

I tried

    $foo = array(1,2);
    $bar = array(3,4);
    for($i=0;$i<=count($bar);$i++)
    {
         $foo[] = $bar[$i];
    }
    //$foo now '1234'

seems to work fine for me.

It's the same thing Rob,
since every time you add a new entry, the call to count($array1) will increase by one, so it will always at the end.

I understand this, which is why I asked. It just seems a little inefficient do add the extra code?

Probably so I didn't have time to test and I just wanted make sure that the additions were gettiong the correct indexes
