Programming PHP

Example 7-1. The chunkify form (chunkify.html) (continued)
Enter a word:
How long should the chunks be?
Example 7-2 lists the PHP script, chunkify.php, to which the form in Example 7-1 submits.
The script copies the parameter values into variables and uses them. Although
the register_globals option in php.ini would automatically create variables from the
parameter values, we don’t use it because it complicates writing secure PHP programs.
