php - Parse a variable as if it were a string literal -


i have string in variable don't control.

$foo = 'hey\nman';

(notice single quotes, it's literal \n not new line character)

now have foo parsed if inside double quotes instead of single. convert literal escape characters corresponding ascii characters. of /r, /n, /b, /t, etc.

i have access $foo can't change code assigns it's value it. option regex can ugly many number of different characters possible. how neatly php handles , wondering if can leverage it.

you can use eval:

$foo = 'hey\nman'; eval ('$b = "' . $foo . '";'); var_dump($b);
