how do you make a string of binary numbers from an array

[Bint]

Hi,
I have an array of numbers, and I need to turn it into a single binary
string. How do I do that?
Thanks
B

Sorry, but what you are trying to do?

You could do something like this:

$string = array(1,2,3,5,6,7);
$output = '';
foreach ($string as $ascii)
{
$output .= chr($ascii);
}

Is that ascii and not binary?

Thanks in Advance...

What are you trying to convert to and from?

For example, ascii code --letter.

Concating the items from decimal to binary?

I'm not really sure how you want to do this, but something like this:

$array = array(7,12,10,2,3);
function concat_dec2bin($v,$w){
$v .= decbin($w);
return $v;
}
$string = array_reduce($array,'concat_dec2bin');

Which will result in 111110010101011 (111 = 7, 1100 = 12,1010 = 10,10 = 2,
11 = 3);

The OP wants a binary string - That's a bit like asking for a cheese
steak.

Looks like the desperate OP should pay more attention in class and not
come here for their coursework. Better still - If that's the limit of
their intellectual engagement with programming they should think of an
alternative career ... such as say a turnip.
