How do I get rid of comma after last array item? - php

Question

I have this array loop:
foreach ( $event_entrance as $event_entrance_s ) {
_e($event_entrance_s,'holidayge');
echo ', ';
}
I'd like to ger rid of comma at the end of the last loop.
Any ideas? Seems simple, but it isn't for me :)

Answer 1

$fn = function($v) { return _e($v,'holidayge'); };
$arr = array_map($fn, $event_entrance );
echo implode(',', $arr);

Answer 2

Two options:
use implode to put things together, it handles this edge case for you easily. Seriously, implode is great
determine if you're on the last element (perhaps with a count, and by accessing the element key) and omit the comma if it's the last element.

Answer 3

What about...
$limit = count($event_entrance);
foreach ($event_entrance as $key => $event_entrance_s) {
_e($event_entrance_s,'holidayge');
if ($key < ($limit-1)) {
echo ', ';
}
}
As long as your keys are integers and sequential, this should work exactly as you intend. If you're using integers, but they are not in any particular order, putting this before your foreach() loop will fix that:
$event_entrance = array_values($event_entrance);
If you are using strings as keys instead of integers, try something like this:
$limit = count($event_entrance);
$i = 1;
foreach ($event_entrance as $event_entrance_s) {
_e($event_entrance_s,'holidayge');
if ($i < $limit) {
echo ', ';
}
++$i;
}

Answer 4

Try something like this:
$event_entrance_count = count($event_entrance);
$loop_number = 1;
foreach ( $event_entrance as $event_entrance_s ) {
_e($event_entrance_s,'holidayge');
if(!$loop_number == $event_entrance_count) {
echo ', ';
}
$loop_number++;
}
