PHP rtrim() function – Trim end of string (right trim) in PHP

In this video I will show you the PHP rtrim() function

==============

By default (without a $charlist), rtrim() removes the following whitespace from the right side of a string:

‘ ‘ spaces
‘t’ tabs
‘n’ new lines
‘r’ carriage returns
‘’ NUL-bytes

============

Use the form:
rtrim($your_string)
for the default behaviour

============

Or use the form:
rtrim($your_string, $your_charlist)
to specify which characters you want to remove

============

You can specify each character individually …

============

… or you can use ranges within your character set using the a..z double dot format.

This sample is functionally identical to the previous one.

============

Check out the code on this page for example usage!
