I fond the fix.
When you use \n in the string and then try to echo it back it doesn't
echo back right. But when you send it the \n works.

Oh, it echos back correctly...
But your BROWSER, which you were using to view it, IGNORES newlines. Or,
more properly, it treats one or more whitespace characters (space,
newline, tab) as a single space.
If you use "View Source" in your browser, you'd see more what you expect.
Or you could use http://php.net/nl2br for HTML output.
Or you could use PRE tags.
Or you could use PHP from the command line.
Or you could use some kind of software to see the raw output of your
web-server, though that's probably a bit more trouble than needed...

Hello,
I am well versed in coding with xhtml which requires all lower case
and am pretty much a newbie at PHP so that is why I am asking this
question.
is this acceptible
if ($_post [sender_email] == "") or does at have to be if ($_POST
[sender_email] == "")
in short, do uppercase and lowercase always have the same meaning.
thx,

PHP is case-sensitive. UppERCase is NOT the same as uppercase. HTML is
not case sensitive only because browsers are forgiving.

PHP is case sensitive. Additionally, quotes, or the absense of quotes,
can change the context. I bring this up because the example you have
above, $_post[sender_email] contains two errors:
* $_post will likely be empty, whereas the PHP superglobal $_POST will
likely contain the data you're looking for ;-)
* $_post[sender_email] refers to the value in the $_post array returned
by an array key that is the same name as the value of the constant
sender_email. You almost certainly were actually meant
$_POST['sender_email'] (note the quotes), which would refer to the
value associated with the array key 'sender_emaail' in the $_POST
array.
You should probably do some reading in the introductory chapters of the
PHP manual, specifically the variables section:
http://php.net/variables
Cheers!

As a friendly suggestion, you should always try before you ask. You
could answer your own question with a few seconds of effort. Typically,
such extreme laziness is not rewarded here. Consider yourself lucky this
time. :-)
If you had instead asked whether you should use $_POST[sender_email] or
$_POST['sender_email'], at least we could give you the benefit of the
doubt and assume that you actually tried them both.

PHP variables are case-sensitive.
PHP FUNCTIONS are not.
You're on your own figuring out if class names/methods are/aren't
case-sensitive this week. :-v

It matches any link with the exception of https links.

I don't see anything in this regex that would prevent https from being
matched, since you don't specify the pattern of the actual url at all.
What is an example of a link that it will match?

Hello,
I am using the following to do link replacing:
preg_match_all("/<\s*a\s+[^>]*href\s*=\s*[\"']?([^\"' >]+)[\"'

It works great for all but 'https' links. I am not that versed in
regular expressions. Would anyone know what I need to put in there so
that it will match on https links?
Thanks,

I'm validating an XML document against a schema using
PHP 5's DomDocument. Easy enough to use, however it
doesn't output the line numbers of errors in the XML
file! Anybody know if it's possible?
Thanks,
John

I'm trying to avoid error messages while iterating
over DOM properties. e.g.
if(is_array($dom->stuff->props)) {
foreach($dom->stuff->props as $prop) {
...
}
}
It works without the is_array() check, but not with
it. I've done var_dumps and $dom->stuff->props is
indeed an array. I've also tried using an intermediate
variable ($stuff=$dom->stuff) then checking that, but
that doesn't work either).

Well, *I* would be confused by the globals, references, and whatnot you've
got running around...
