How do I have a regex statement that accepts any character except new lines. This includes anything but also includes new lines which is not what i want:
"/(.*)/"

The dot . does not match newlines unless you use the s modifier.
>>> preg_match("/./", "\n")
0
>>> preg_match("/./s", "\n")

As written on the PHP Documentation page on Preg Modifiers, a dot . does NOT include newlines, only when you use the s modifier.

The following regular expression should match any character except newlines
/[^\n]+/

yes, except the original matches the empty string and this one requires at least one non-linebreak character... "/[^\n]*/" (and if you're on Windows, you might want to exclude \r as well...)
The default behavior shouldn't match a new line. Because the "s" modifier is used to make the dot match all characters, including new lines. Maybe you can provide an example to look at?

#!/usr/bin/env php
<?php
$test = "Some\ntest\nstring";
// Echos just "Some"
preg_match('/(.*)/', $test, $m);
echo "First test: ".$m[0]."\n";
// Echos the whole string.
preg_match('/(.*)/s', $test, $m);
echo "Second test: ".$m[0]."\n";
So I don't know what is wrong with your program, but it's not the regex (unless you have the /s modifier in your actual application.

this is strange, because by default the dot (.) does not accept newlines. Most probably you have a "\r" (carriage return) character there, so you need to eliminate both: /[^\r\n]/
ah, you were using /s
