printing everything in an explode()

[tjmbc]

i have an array that I used explode() on to break it up into variables

 

i can echo each variable by calling it with $variable[0] then $variable[1]

 

but how do I print all of the variables without calling each one individually?

 

i'm guessing its something like

 

while(???some sort of code to that i don't know???) {

 

  echo $variable;

 

}

[trq]

<?php

  $arr = array('foo','bar','bob');

  foreach ($arr as $k) {
    echo $k."\n";
  }

?>
