Description
array 
explode ( string separator, string string [, int limit] )
     Returns an array of strings, each of which is a substring of
     string formed by splitting it on
     boundaries formed by the string separator.
     If limit is set, the returned array will
     contain a maximum of limit elements with
     the last element containing the rest of
     string.
    
     If separator is an empty string (""),
     explode() will return FALSE.  If
     separator contains a value that is not contained
     in string, then explode() will
     return an array containing string.
    
     If the limit parameter is negative, all components
     except the last -limit are returned. This feature
     was added in PHP 5.1.0.
    
     Although implode() can, for historical reasons,
     accept its parameters in either order,
     explode() cannot. You must ensure that the
     separator argument comes before the
     string argument.
    
Note: 
      The limit parameter was added in PHP
      4.0.1 
     
     
| Example 1. explode() examples | 
<?php// Example 1
 $pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
 $pieces = explode(" ", $pizza);
 echo $pieces[0]; // piece1
 echo $pieces[1]; // piece2
 
 // Example 2
 $data = "foo:*:1023:1000::/home/foo:/bin/sh";
 list($user, $pass, $uid, $gid, $gecos, $home, $shell) = explode(":", $data);
 echo $user; // foo
 echo $pass; // *
 
 ?>

| Example 2. limit parameter examples | 
<?php$str = 'one|two|three|four';
 
 // positive limit
 print_r(explode('|', $str, 2));
 
 // negative limit (since PHP 5.1)
 print_r(explode('|', $str, -1));
 ?>

 The above example will output: | Array
(
    [0] => one
    [1] => two|three|four
)
Array
(
    [0] => one
    [1] => two
    [2] => three
) |
