How to explode this into an array of variables?

Question

I already have the following in place to explode the br's in $tmp..

  $tmp = explode('<br>', $tmp);
  echo $tmp[0];
  echo "<br>";
  echo $tmp[1];

How can I explode $tmp[0] to grab each bit of text, turn them into an array, ie: $pipetxt[0], $pipetxt[1], etc. without the pipelines..

Can I do the exact same as the above, after the above occurs.. but go;

$pipetxt = explode('|', $tmp[0]);
echo $pipetxt[0];
echo "<br>";
echo $pipetxt[1];

Thank you!

I haven't tested the second explode.. was just checking if that was the correct way and if I was able to do it on an already exploded array? — iCeR

There is no such thing as an "already exploded array". Arrays and strings don't have a concept of being exploded. $tmp starts as being a string (some text) and when you explode it you get an array of strings (a "bag" of strings). So your $tmp variable now points at a bunch of strings. When you then explode $tmp[0] what you are doing is taking the "0th" (first) element of the array (another string) and exploding it to obtain a new array of strings. You can continue in this way indefinitely (the worst that can happen is getting an array with a single string in it). — Zecc

Your explode looks good, and you can output all your $pipetxt with foreach():

foreach($pipetxt as $out)
  echo $out . "<br>";

Yes

But you should probably adopt some loops.

$tmp = explode('<br>', $tmp);

foreach($tmp as $pipeline){
 $pipetxt_array = explode('|', $pipeline);
 foreach ($pipetxt_array as $output){
  echo $output."<br />";
 }
}
