Definition and Usage
The strtok() function splits a string into smaller strings.

Syntax
strtok(string,split)  

Parameter Description
string Required. Specifies the string to split
split Required. Specifies one or more split characters


--------------------------------------------------------------------------------

Example
In the example below, note that it is only the first call to strtok() that uses the string argument. After the first call, this function only needs the split argument, as it keeps track of where it is in the current string. To tokenize a new string, call strtok() with the string argument again:

$string = "Hello world. Beautiful day today.";
$token = strtok($string, " ");

while ($token != false)
  {
  echo "$token
";
  $token = strtok(" ");
  } ?>  

The output of the code above will be:

Hello
world.
Beautiful
day
today.
