Entry

How can I convert all entries in an associative array into variables?

How can I make variables from the key names in an array?

Use the extract() function:
  http://www.php.net/extract
  $arr = array('a' => 'apple', 'b' => 'banana');
  extract($arr);
  print $a; // apple
  print $b; // banana
One possible use of extract() is on fetched data from a database.  For
example:
  $result = mysql_query("SELECT foo,bar FROM tablename");
  while ($row = mysql_fetch_assoc($result)) {
    extract($row);
    print "$foo : $bar\n";
  }
Another option is to use a loop and variable variables, like so:
  $arr = array('a' => 'apple', 'b' => 'banana');
  while (list($key, $value) = each($arr)) {
    $$key = $value;
  }
  print $a; // apple
  print $b; // banana
