PHP正则表达式不是新行

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

The following regular expression should match any character except newlines

/[^
]+/

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

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

ah, you were using /s

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
test
string";

// Echos just "Some"
preg_match('/(.*)/', $test, $m);
echo "First test: ".$m[0]."
";

// Echos the whole string.
preg_match('/(.*)/s', $test, $m);
echo "Second test: ".$m[0]."
";

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.
