我怎样才能从某个位置取出一部分弦？ 在PHP中

Question

I have a simple question:

if I have this string like:

$mystring="|10|20|30|40";

how I can get the number 30 from $mystring?

I would like to use "|" for a separator, I know the number of the tokenat (2), but I didn't find any code for how to take a specific part of a text from the "|", and start from a specific tokenat (the second in this case)

and if I use a parameter "1", will get 20

someone has any idea?

Thank you very much :)

Check out explode() :

$mystring="|10|20|30|40";
$parts = explode('|', $mystring);
print_r($parts);
