PHP regex not new line

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:

"/(.*)/"

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

#!/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.

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?

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

The dot . does not match newlines unless you use the s modifier.

>>> preg_match("/./", "\n")
0
>>> preg_match("/./s", "\n")
1
