Removing the last space in a string

Issue

I have to remove the last space from a string

(\s)a(\s)b(\s)

so, essentially id like my string to end up as:

(\s)a(\s)b

just to be clear, id prefer searching against ‘ ‘ instead of performing a regex expression, but i used regex patterns so you could understand the spaces.

How do I do this using php?

Solution

Using PHP, the rtrim() function is probably what you need.

rtrim — Strip whitespace (or other characters) from the end of a string
