Array limiting

[F_SH]

Whenever a certain event occurs, value x is added to the end of array myarray. Now this is fine for a while, but since I'm drawing the contents of my array, I need to limit its size to about 20 entires, the most recent ones.

So far, my code for adding an element, checking to see if it's over the 20 element limit and deleting the first element does not work:

	$numbers[] = $latestnumber;

if (count($numbers) > 20)
	{
	$numbers= array_shift($numbers);
	echo "Numbers Array Shifted.";
	}

Whenever the condition is met, however, the array srinks to a size of one, rather than knocking one off. Can anyone see why and how to fix it?😕

// this will add one element in the beginning of the array,
// and then remove the last one...
if(count($numbers) > 20)
{
   array_unshift($numbers,$latestnumber);
   array_pop($numbers);
}

Hi F*SH,

take a look at the manual:
http://www.php.net/manual/en/function.array-shift.php

array_shift() shifts the first value of the array off and returns it

so, if you assign the return value to your array variable, you are overwriting the array with the value that was supposed to be removed.

just calling array_shift($numbers); should do what you wanted.
