Ambiguity in result if ini_set

I find that w.r.t. docs:

string ini_set ( string varname, string newvalue)

Sets the value of the given configuration option. Returns the old value
on success, FALSE on failure.

if the old value is FALSE (or the indistinguishable NULL, or ""), the
result cannot be used to discover failure.

Have I misunderstood? Or must I discover failure some other way e.g.
ini_get.

Thanks.

Hi Chris,

CHeck the return value with === or !== e.g.

if(ini_set("somevar", "somevalue")===FALSE){
if(ini_set("somevar", "somevalue")!==FALSE){

If the old value was FALSE or 0 it will be returned as string, not boolean.
