Changing arrays at runtime

[aktar]

Here is the code


[PHP]$alphabet = array("a","b"," c");
$number_of_lett ers = 3; //initial amount of characters

foreach($alphab ets as $letter)
{
print $letter;

if ($number_of_let ters != 26)
{
//add another character to the $alphabet array
//AND increase the $number_of_lett ers by 1
}
}[/PHP]

Now here is the question :

The above code will only process the initial array values even thoug the array is being added to, ie it will print only a,b and c

Logically, it should carry on printing as the $aphabet array is being continiously chaged.

Any thoughts appreciated

Heya, Aktar.

In this case, you'll want to use a for loop, as the condition is evaluated at every iteration:

[code=php]
for( $__i = 0; $__i < $number_of_lett ers; ++$__i )
{
.
.
.
}
[/code]

When you add a letter to the array, be sure to increment $number_of_lett ers. Once you stop adding letters, your script will stop incrementing $number_of_lett ers, and then your loop will (eventually) terminate.
