```
A note to anyone nesting a while loop inside a while loop....
```

Consider the example below:

$one = array("10", "20", "30", "40");

$two = array("a", "b", "c", "d");

$i=0;

while($i < count($one)) {

while($a = each($two)) {

echo $a[1]." - ".$one[$i].", ";

}

$i++;

}

This will return the following:

a - 10, b - 10, c - 10, d - 10

So in effect the main while loop is only doing one iteration... and not 4 as expected....

Now the example below works as expected..

$i=0;

while($i < count($one)) {

foreach($two as $a) {

echo $a." - ".$one[$i]."\n";

}

$i++;

}

by returning:

a - 10, b - 10, c - 10, d - 10, a - 20, b - 20, c - 20, d - 20, a - 30, b - 30, c - 30, d - 30, a - 40, b - 40, c - 40, d - 40

So there is clearly a difference on how while statements work in comparison to other looping structures.

I think it would be good to have an explaination of this strange behaviour.
