Hi,
i'm on PHP training and our lector is telling us that to avoid counting an
array item amout thanks count($my_array), he tells we can do:
while($my_array)
{
... do something
}
but from experience this is an infinity loop...
it should be always something like
$count = count($my_array);
while($i <= $count)
{
...
do something
...
$i++;
}
has someone already use such syntax ? i mean as the first one.
thx.
While you teacher technically is wrong, you probably could implement
something using the next() and current() array functions, though you're
best to just use a foreach loop. foreach was designed specifically as an
array looping construct, so it's optimized pretty well.
Only thing to note with the foreach is that you are actually working on
a copy of the array, so if you intend to modify it, pass it by reference.
