How can I know if the last char of a $string is ',' ?

Answer 1

There are a few options:

if (substr($string, -1) == ',') { 

Or (slightly less readable):

if ($string[strlen($string) - 1] == ',') { 

Or (even less readable):

if (strrpos($string, ',') == strlen($string) - 1) { 

Or (even worse yet):

if (preg_match('/,$/', $string)) { 

Or (wow this is bad):

if (end(explode(',', $string)) == '') { 

The take away, is just use substr($string, -1) and be done with it. But there are many other alternatives out there...

Answer 2

$string = 'foo,bar,'; if(substr($string, -1) === ','){     // it ends with ',' }
