Split Array Items with a Character

Question

I have an array with a few items in it (e.g. item1, item2, item3) and I want to split each item with a "|", so it will look like this at the end: item1|item2|item3.

Answer 1

You must use the implode() function :

$arr = array('item1', 'item2', 'item3');
$str = implode('|', $arr);
var_dump($str);

Will get you :

string 'item1|item2|item3' (length=17)

---

As a sidenote : what you are doing here is joining (join() is actually an alias of implode()), and not splitting.

Splitting would be the opposite operation, and would be done, in PHP, using the explode() function :

$arr = explode('|', 'item1|item2|item3');
var_dump($arr);

would get you :

array
  0 => string 'item1' (length=5)
  1 => string 'item2' (length=5)
  2 => string 'item3' (length=5)

Answer 2

you can use implode('|', $array);

Answer 3

That looks like joining and not splitting.

You can use the implode function as:

$str = implode('|',$arr);

Answer 4

a = ["item1", "item2", "item3" ]

print "|".join( a )

Prints out item1|item2|item3
