Hello everybody :)
I'm really intrigued on something... In what real-world applications could
an extension of a class be really useful?
Let's say I have this code:
class foo {
function hello_world($a) {
echo 'foo hello world';
}
function bye_world() {
echo 'foo bye world';
}
}
Very good.
Thank you.

Hello again list.
My code for stripping characters is below. I'm hoping to get feedback

My output must look like this (no quotes):

Hey everyone,
I have a question about logins. Let's say that I want to allow each
user account to login only once at a time. I would then need some kind
of locking mechanism to make sure that the same user can't login again
somewhere else until first logging off. What's a good way to achieve

BUT, all the ereg_* has been depricated. DO NOT USE THEM if you want your code

The definition of letters and digits is controlled by PCRE's character

Perhaps, ereg_replace("your regex", "replacement_string", String
$variable).

Hello,
can this resolve your problem?
$trans = array(
"from" => "to",
"another" => "to");
$moditem = StrTr($moditem, $trans);

Hello List.
I need to remove characters from a string and replace them with and
underscore.
So instead of having something like:
$moditem = str_replace("--","_","$mystring");
$moditem = str_replace("?","_","$mystring");
$moditem = str_replace("!","_","$mystring");
etc.

Mike,
A couple of things that I could understand reading carefully at the error.
1. reset takes an array as the input and perhaps your $thumbsarray is *not *an
array? Reset will set the internal pointer to the start of the array.
2. Warning # 2 is very closely related to #1 since you can iterate
