[SOLVED] Strip last char off string

[EchoFool]

How do you strip off the last character of a string even if you don't know how long the string is initially?

 

Say i have like 'hey,hey,hey,hey,"

 

So i want to rid of the last , symbol.. though there could be many more characters in the string.. whats the best approach ?

$str = substr($str, 0, -1);

Try this:

$lenght = strlen("hey,hey,hey,hey,");

$start = $length - 1;

echo substr("hey,hey,hey,hey,",$start,1); 

 

Or try what thebadbad gave you...

 

God I am thinking the hard way today.... -.-
