Just do:
echo substr[$string, 0, -3];
You don't need to use a strlen call, since, as noted in the substr documentation:
If length is given and is negative, then that many characters will be omitted from the end of string

//if length is negative it starts removing from the end
$result = substr[$name,0,-3];
echo $result;Output:
