Adding or condition in for loop

Question

How can I add or in for loop check? for example:

for ($i=1; ($i <= $untilPoint) or ($i <= $points); $i++){
.. code ...
}

If it doesn't work (does it?), then you could turn it into a do/while loop. — mario

Exactly what you typed is valid PHP. For example, this program:

<?
$untilPoint = 3;
$points = 5;
for ($i=1; ($i <= $untilPoint) or ($i <= $points); $i++){
    echo("$i\n");
}
?>

prints this:

(tested in PHP 5.2.17, run from the Bash prompt).

That said, I wonder if maybe you really need and rather than or? If $i is an index into an array of points, where $points is the number of points and $untilPoint is an arbitrary cutoff, then you want and, not or.

This is how it should be done, probably it runs slightly faster. You can separate with , see http://php.net/manual/en/control-structures.for.php for more information

<?
$untilPoint = 3;
$points = 5;
for ($i=1; $i <= $untilPoint, $i <= $points; $i++){
    echo($i , "\n");
}
?>
