Whats the different of explode() and wordwrap() ?

Answer :

just see this example for explode()

<?php

$birthday=’1998-12-11′;

//we need to split the component to date, month and year

$day_parts=explode(’-',$birthday);

// we use - as tool to separate, now print

$date_component=$day_parts[2];

$month_component=$day_parts[1];

$year_component=$day_parts[0];

?>

Wordwrap will ‘wrapping’ user input, like formatting crazy user who type ‘aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa’ till he satisfied and brake our guestbook table.

Just make sure to add number bigger than 0 to enable wordwrap.
