Str_replace Function. Welcome to todays tutorial, you will be learning the str_replace function.

str_replace is a very useful function.
What str_replace does is it replaces text with the desired text.
For an example i will make a function.
Code:

function filter($var){ //name the function
$var = str_replace('swear','****',$var);
$var = nl2br($var); //add line breaks
return $var; //return it
}
?>

What this does is it replaces the word 'swear' with '****'
This function can be useful for a number of things like a swear filter, or removing spaces from usernames.
