$array =  explode('|', $set_of_numbers);

answer

["","1","","10","","12",""]

I need so

["1","10","12"]

as can be done thank you for previously

"the numbers are separated by comma '|1||10||12|'" Looks like they're not — user8034901

Use this, array_filter() function will removes your empty/blank values from array & will return array which has values only.

$set_of_numbers = '|1||10||12|';
$array =  array_filter(explode('|', $set_of_numbers));

Can you try this,

$set_of_numbers = '|1||10||12|';
$array = array_filter(explode("|", $set_of_numbers), function($value) { return $value!== ''; });

It will work you can use this, I tested this on phpfiddle.

You can simplify that filter to array_filter(..., 'strlen').

Try this. This will work.

$set_of_numbers = '|1||10||12|';
$array =  explode('|', $set_of_numbers);
$array = array_filter($array);

You can also use regular expression:

<?php

$a = '|1||10||12|';
$matches = [];
preg_match_all('/(\d+)/', $a, $matches);
var_dump($matches[1]);

Try this

$array = trim($array, '|');
$array = explode('||', $set_of_numbers);

That works very specifically for this example, but I'm not sure the spec is that there will always be || in the middle and | and the ends…

Sure, this is a specific answer. But judging by the question, that's what he will always have in his $set_of_numbers.

@deceze Wouldn't that also be true for all the other answers?

@kerbholz No, array_filter works regardless of how many | there are or in what combination.

@deceze Oh, ok, I see, I thought you were talking about the seperator being , or something. Nevermind ;)
