logical problem with explode

[antoinep]

Hello everybody

$a="";
$b=explode(",",$a);
for (i=0; count($b); i++)
{
echo $i;
}

normally nothing must happen.
But he echos me a 0, sometimes a 1.
Why??

Really? Once I've fixed the syntax errors I get
012345678910111213141516171819202122232425....
ad infinitum, for an obvious reason: count($b) is equal to 1, and always equal to 1.

$a="";
$b=explode(",",$a);
for (i=0; i<count($b); i++)
{
echo $i;
}

Well, since count($b) is equal to 1, and assuming you know that the i's in that same line should be $i's - I predict that if I ran it I'd get 0.

Yep. Works as I expected. Are you saying that code sometimes echoes 1?
