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.
Probably the easiest way for doing this is using foreach:
$a = array(1,2,3,4,5);
foreach ($a as $i) {
print $i."<br>";
}
This outputs:
1
2
3
4
5
This for e.g. gives an infinite loop:
$a = array(1,2,3,4,5);
while ($a) {
print $i."<br>";
$i++;
}
So you are right because $a will always evaluate as true since it not empty. For these kinds of questions you should read the manual first and then ask here.
