Count occurences of something in a string

[LemonInflux]

Hello, all. My query is this:

 

Say I have a string like this:

 

$var = afboij|abfouhenh|naxcbejkh|lkj

 

Just random letters, but separated by a |. How do I count the number of |s in the string?

<?php
$var = 'afboij|abfouhenh|naxcbejkh|lkj';

echo substr_count($var, '|');       // 3
?>
