  • "\x0B" (ASCII 11 (0x0B)), a vertical tab.

"\t\tThese are a few words :) ...  ";
$binary "\x09Example string\x0A";
$hello  "Hello World";
var_dump($text$binary$hello);

print 
"\n";

$trimmed rtrim($text);
var_dump($trimmed);

$trimmed rtrim($text" \t.");
var_dump($trimmed);

$trimmed rtrim($hello"Hdle");
var_dump($trimmed);

// trim the ASCII control characters at the end of $binary
// (from 0 to 31 inclusive)
$clean rtrim($binary"\x00..\x1F");
