I dont see why this is happening....

[nca]

$d = "38-44-85-91";

$disc1 = strtok($d,"-");
echo "1: $disc1<br>";

$disc2 = strtok($d,"$disc1-");
echo "2: $disc2<br>";

$disc3 = strtok($d,"$disc1-$disc2-");
echo "3: $disc3<br>";

$disc4 = strtok($d,"$disc1-$disc2-$disc3-");
echo "4: $disc4<br>";

It is outputing:
1: 38
2: 44
3: 5
4: 91

3: should be 85... :bemused:

Why not just do it this way:

. . . code removed . . .

Or, better yet... if you're using a simple string like that, and don't need it to be dynamic:

list($disc1, $disc2, $disc3, $disc4) = explode("-", $d);

strtok() splits a string based on the characters presented in the second variable. In this case, for $disc3, you are passing a call like this: strtok("38-44-85-91", "38-44-"). The resulting string will therefore be tokenized whenever it encounters a "3", "8", "-", or "4". There is no way for strtok to return "85", because "8" is in the list of token delimiters.

I think that you are trying to do this:

$d = "38-44-85-91";

$disc1 = strtok($d,"-");
echo "1: $disc1<br>";

$disc2 = strtok("-");
echo "2: $disc2<br>";

$disc3 = strtok("-");
echo "3: $disc3<br>";

$disc4 = strtok("-");
echo "4: $disc4<br>";

Personally, I think a better way to do this would be to use the explode() function.

Ooops.....

As per the PHP manual:

Note that only the first call to strtok uses the string argument. Every subsequent call to strtok only needs the token to use, as it keeps track of where it is in the current string. To start over, or to tokenize a new string you simply call strtok with the string argument again to initialize it.
