   thank you, I know it, but I want know why we must use double backslash if use quote. and we can use single backslash when don't use quote. why design by this.

   Thanks for the report, but I couldn't replicate this breaking with an env file containing:

   TEST="aaaaaaaaa vvvvvaaaaa\aaaanaa"
   

   Perhaps you need to increase the value of pcre.backtrack_limit on your server.

   @fyzzy1943 I've fixed the error message so it lets you know you need to escape the backslash. It now says "invalid escape sequence" instead of crashing with the preg error.
