while question

[johnie]

Hi.

$parent_id = 1000;
while($parent_id) {
do_something;
}

What does this do. It repeats itself until parent_id becomes >1000 or it just sets the variable to evaluate to TRUE?

$parent_id = 1000;
while($parent_id) {
do_something;
}

this goes into an infinite loop, cause the condition is always true

$parent_id = 1000;
while($parent_id < 1010) {
do_something;
$parent_id++;
}

keeps doing something till parent_id reaches 1009, you have to keep incrementing the value inside the loop else it will become an infinite loop.
