How do I remove the last comma from a string using PHP?

Question

I am using a loop to get values from my database and my result is like:

'name', 'name2', 'name3',

And I want it like this:

'name', 'name2', 'name3'

I want to remove the comma after the last value of the loop.

Answer 1

Use the rtrim function:

rtrim($my_string, ',');

The Second parameter indicates the character to be deleted.
