There are reset() and end() functions for array pointer P
manipulation. Is there a way to set or read it directly? P = 3?
loop
next($a);
break on some count
seems to be the only way to do it.
Thank you.

$x = $a[3];

The square bracket operator does not seem to alter the array pointer:
<?php
$foo = range(0, 99);
var_dump(next($foo));
var_dump(next($foo));
$foo[50];
var_dump(next($foo));
?>
.... prints this:
int(1)
int(2)
int(3)
Array pointers are not very practical but I suppose the are not widely
used anyway.
