用php替换\\ n到字符串中的新行

Question

I just want to replace "\\n" characters to new line in a string using php, like that :

string 'foo\n\nbar'

to

string 'foo

bar`

Anybody have an idea ? Thanks.

Answer 1

use str_replace('\\n', PHP_EOL, 'foo\\n\\nbar');

<?php
header('Content-Type: text/plain');

$string = 'foo\n\nbar';

$string = str_replace('\n', PHP_EOL, $string);

echo $string;
?>

Shows:

foo

bar
