Equals Symbol Causes "Failed to parse dotenv file due to an invalid name".

[bljdavidson]

How do you escape the = symbol? It's causing the "Failed to parse dotenv file due to an invalid name" error because of it. It's part of a multiline value.

SERVICE_ACCOUNT_JSON = '{
    "type": "service_account",
    "project_id": "project id",
    "private_key": "-----BEGIN PRIVATE KEY-----\nMIIE ..... DgQw==\n-----END PRIVATE KEY-----\n",
    "client_email": "email@account.com"
    "client_id": "1234567890123456789",
    .....
    .....
}',

It is failing at the 2 == symbols at the end of the "private_key" value. If I remove the 2 symbols, it works, but unfortunately, it won't authenticate.

I think the colon in the name is the error here surely?

Also, the single quotes don't look right.

I do get some weird behaviour with multiline variables at the moment:

TEST="test
     test=="test"
     test"

Parses as:

  ["TEST"]=>
  string(41) "test
            test==
            test""

If I try escaping the quotes:

TEST="test
     test==\"test\"
     test"

I get a fatal error:

Fatal error: Uncaught Dotenv\Exception\InvalidFileException: Failed to parse dotenv file due to a quote parsing error (PREG_BACKTRACK_LIMIT_ERROR). Failed at ["test]. in ..\vlucas\phpdotenv\src\Parser.php:163

More interestingly, this parses okay but still includes the surrounding quotes (this seems to happen for single-line values without spaces, too):

TEST="test
     test\"test\"
     test"

Parses as:

string(21) ""test
     test"test""

@GrahamCampbell Sorry this was a typo on my behalf. I've removed that now.

@hexus I have tried with and without the quotes. I have also tried to escape the = symbol with the backslash but to no avail. As soon as I remove both = symbols, it works but of course it fails to authenticate as they're needed.

I really appreciate both your help :)

[GrahamCampbell]

Right, it looks like the implementation of multiline variables does not support quotes being contained within the string. If we look at the implementation (https://github.com/vlucas/phpdotenv/blob/v3.1.0/src/Lines.php), a multi-line variable's final line is defined to be the first line containing a quote without an equals.

[GrahamCampbell]

@bljdavidson the file provided in the OP is still invalid syntax as far as I can see?

[GrahamCampbell]

@hexus Thanks for those test cases. I'll incorporate them into the test suite.

I won't have time to look into fixing this until Sunday I'm afraid. I've just had a go now, and a good solution isn't immediately obvious to me.

@GrahamCampbell Thanks so much for your help. In the mean time, I have tried to make the JSON into a single line and 2 things happen:

• If I keep the variable name as KEY = VALUE, the value just becomes an empty string.
• If I change it to KEY: VALUE, I get the same error, failing at the = symbol.

So I'm not sure if it's only related to just multiline :/.

P.S. Please forgive me if I've misunderstood anything, as I'm not advanced in PHP :).

Awesome. Nice work 👍

@bljdavidson @hexus @Korbeil I've prepared a fix at #322. Please let me know what you think.

[GrahamCampbell]

@bljdavidson The following should be the format you want:

SERVICE_ACCOUNT_JSON="{
    \"type\": \"service_account\",
    \"project_id\": \"project id\",
    \"private_key\": \"-----BEGIN PRIVATE KEY-----\\nMIIE ..... DgQw==\\n-----END PRIVATE KEY-----\\n\",
    \"client_email\": \"email@account.com\"
    \"client_id\": \"1234567890123456789\",
    .....
    .....
}"

Notice how I've escaped all double quotes and backslashes.

[GrahamCampbell]

@hexus Your example of:

TEST="test
     test\"test\"
     test"

should now parse as:

test
     test"test"
     test

[hexus]

Fabulous 🎉

Thanks very much!
