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
...
$i++;
}
has someone already use such syntax ? i mean as the first one.
thx.
sounds like a poor teacher, however I have a feeling he simply wants you
to be able to count the items in an array without using the count()
function. In this case you would be best to use a foreach loop.
you are correct in saying that a while($myarray) loop would be infinite,
unless you use a function to reduce the array on each iteration of the
while loop as such:
<?php
$myarray = array('a','b','c','d','e','f');
$count = 0;
while ( $myarray ) {
$count += array_pop($myarray) ? 1 : 0;
};
echo $count;
?>
but.. get a new teacher :p (no offense)
