Remove the last character from a string

Question

What is the fastest way to remove the last character from a string?

I have a string like:

a,b,c,d,e,

I would like to remove the last ',' and get the remaining string back:

OUTPUT: a,b,c,d,e

What is the fastest way to do this?

Answer 1

In response to the query, rtrim() will trim the string's end by whatever number of characters specified in the second argument. If you're looking for a single comma, the code below might work:

$newarraynama = rtrim($arraynama, ",");

The rtrim() could be a good choice if you don't know whether the extra character could be present or not. Unlike substr-based solutions, it will return a, b, c, d, e from a, b, c, d, e. I hope this helps you.
