Confusing Functions

Posted on 16th Feb 2014 07:03 pm by admin

So, I've been reading up on Functions and I like them! However, I need some help using variables in functions, since it's kind of confusing.

I just made these functions:

<?php

function Protect($var){
$var = mysql_real_escape_string(htmlentities(stripslashes($var)));
}

function Preserve($var){
$content = nl2br(str_replace(" ", "&nbsp;", $var));
}
?>


Neither of them work. Dunno why.

From what I understand...

If I do this:
function HelloThere($var){

Then when I use the function I can go...
HelloThere($hello);

And the $hello variable will be substituted for $var from when I defined the function. Am I not right, confusing, or misled? Please help!!!

Thanks.


PS I originally had this, but it didn't work:
<?php

function Protect($var){
$variable = $var;
$protect1 = mysql_real_escape_string($variable);
$protect2 = htmlentities($protect1);
$protect3 = stripslashes($protect2);
}

function Preserve($var){
$content = nl2br(str_replace(" ", "&nbsp;", $var));
}
?>
