Please consider this code :
<?php
$a = array("One","Two","Three");
foreach ($a AS $k=>$v) {
}
var_dump(current($a));
// outputs boll(false);
that's expected as foreach moves the internal array pointer, it's
documented.
now consider this :
<?php
$a = array("One","Two","Three");
foreach ($a AS $k=>$v) {
current($a);
}
var_dump(current($a));
// outputs string("One");
When using the internal pointer just by calling current() (so not moving
it), the output of the foreach loop has changed ...
Can someone explain that ?
regards.
