Question

I’ve not used strtok before, the PHP manual doesn’t give a very good explanation.

I want to loop through the tokenized string more than once. How do I reset it back to the beginning?

Answer 1

Just call again strtok with two params and that is:

$tok = strtok($string, $tokens);

From the strtok official doc:

To start over, or to tokenize a new string you simply call strtok with
the string argument again to initialize it.
