getenv non covered system method

[cenxun]

This error occurred when I cloned the develop branch and configured the env file

It looks as if genenv has not rewritten the system method

BASEPATH/Config\DotEnv.php at line 124, setVariable method

	/**
	 * Sets the variable into the environment. Will parse the string
	 * first to look for {name}={value} pattern, ensure that nested
	 * variables are handled, and strip it of single and double quotes.
	 *
	 * @param string $name
	 * @param string $value
	 */
	protected function setVariable(string $name, string $value = '')
	{
		list($name, $value) = $this->normaliseVariable($name, $value);

		if (! getenv($name, true)) putenv("$name=$value");
		if (empty($_ENV[$name])) $_ENV[$name] = $value;
		if (empty($_SERVER[$name])) $_SERVER[$name] = $value;
	}

What do you have set in your .env file?

[cenxun]

yes, app and database

Hmm. What version of PHP are you using? According to PHP's own docs getenv() most definitely supports 2 parameters. Is there any chance you have something custom in your PHP setup that is overwriting the getenv function?

😳 , use PHP Version 7.0.8，Maybe I used the third party integrated development environment

phpstorm definition

/**
 * Gets the value of an environment variable
 * @link http://php.net/manual/en/function.getenv.php
 * @param string $varname [optional] <p>
 * The variable name.
 * </p>
 * @return string|array|false the value of the environment variable
 * varname or array with all environment variables if no variable name
 * provided, or false on an error.
 * @since 4.0
 * @since 5.0
 * @since 7.1
 */
function getenv ($varname = null) {}

and

[root@localhost application]# php --rf getenv
Function [ <internal:standard> function getenv ] {

  - Parameters [1] {
    Parameter #0 [ <required> $varname ]
  }
}

[root@localhost application]# php -v

Did you figure out what was causing it?
