I'm quite new to PHP. How can I change this foreach loop to only loop twice?
<?php
foreach($results as $row):
?>

You need a counter variable, which you can simply increment and check if it is equals to 2, if yes break the loop.Rizier123– Rizier1232016-04-22 11:34:04 +00:00Commented Apr 22, 2016 at 11:34

Do please give it some though / Give it a try yourself, nothing will explode if you try, and it's the best way to learn.Epodax– Epodax2016-04-22 11:35:29 +00:00Commented Apr 22, 2016 at 11:35

Try this code, you just need a counter variable, initialize your counter variable from zero and increment it after each iteration.
<?php
$counter = 0;
foreach($results as $row) {
//your code
if($counter == 1)
{
break;
}
$counter++;
}
?>

Welcome @jord49 :)
You could iterate up to the size of the array or 2 - the smaller of the two.
<?php
$maxInd = min(2, count($results);
for ($i = 0; $i < $maxInd; ++$i) {
$row = $results[$i];
// Do something interesting with $row
}
?>

<?php
for ($i = 0, $count = count($results); $i < $count; ++$i) {
var_dump($results[$i]);
// or assign it to $result variable
$result = $results[$i];
}
?>
But this will work only for collection there are some examples for example generators where you must use foreach.
