First, trim off the pipe at the end of your input.
$str = rtrim($a, '|');
Then, explode on the pipe.
$a = explode('|', $str);
Alternatively, do the split normally and then filter out the whitespace entries as a post-processing step.
$a = array_filter($a, 'strlen');

+1 Only correct answer on this question. Without trimming last pipe, you will get empty element in array. I don't understand how other answers has got upvote.

check @alex answer. You need to trim the last
| or else you will get last empty element in array.You can do achieve what you want to this way:
$a = "A1|A2|A3|";
$a = rtrim($a, '|'); // Trimming the final |
$exploded = explode("|", $a); // Extracting the values from string.
var_dump($exploded);
Hope it answers your question. Refer rtrim and explode on official documentation site for more relevant details.

$newA = explode("|",$a);
print_r($newA);
