Explode + arrays + me = hopeless

I know that code works and puts the exploded string into an array how can I get the data from the array without having to print all of the exploded parts but say to variables so the first one in the array would become $ex1 2nd in array $ex2 etc? as I need it to ignore the first two and last 1 fields of the array and on the 4th do some maths on it so how would I do that?

probably best to use strtok():

<pre><?
$polink = "protocol://|file|File.Name|687122432|7f006a56ea5a4068c32351b2c837f763|/";
$token = strtok($polink,"|");
$i=1;
$ex1 = $token;
while ($token!="")
{
    $i++;
    $variable = "ex".$i;
    $token = strtok("|");
    $$variable = $token;
}
for($a=1;$a<=$i;$a++)
{
    $variable = "ex".$a;
    echo $$variable."<br>";
}
?></pre>

obviously you dont need the for loop at the end - that's just to check that it's worked okay.

but reading your post again, and assuming that you're always going to supply a string which will be split into 4 parts (only the third of which you want to keep) then why not do as you've done and then do something really simple like:

$important_bit = $ex[2];

and then you can do your maths stuff on $important_bit.

Or am i missing something?

PS Also, there are 6 parts to your array ($ex[0] which contains "protocol://" through to $ex[5] which contains "/")

thanks I did it the second way.
