chop

string chop(string string) 

Strips trailing whitespace from a string.

Returns:

String stripped of trailing whitespace

Description:

chop() removes all trailing whitespace characters from the given string. These characters include the horizontal tab (\t), linefeed (\n), vertical tab (\013), carriage return (\r), and space (' '') characters.

Note:

Perl coders may be misled by this function’s name. Perl’s chop() function removes the last character from a string, while PHP’s chop() behaves more like Perl’s chomp(). To simulate the behavior of Perl’s chop(), see the examples.
