PHP正则表达式不是新行

Question

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:

"/(.*)/"

Answer 1

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

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

Answer 2

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

Answer 3

以下正则表达式应匹配除换行符之外的任何字符

/[^\n]+/

Answer 4

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?

Answer 5

#!/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.

Answer 6

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
