"wp config create" generates wrong DB_PASSWORD in wp-config.php when db password has "

Bug Report

• Yes, I reviewed the contribution guidelines.
• Yes, more specifically, I reviewed the guidelines on [how to write clear bug reports](https://make.wordpress.org/cli/handbook/ /bug-reports/).
• I'm not 100% sure I understood everything, though. I swear I searched for similar issue.

Describe the current, buggy behavior

If db password has ", then wp config create --dbpass='abcd"efgh' --other... will create a wrong DB_PASSWORDline in wp-config.php. The resulting line is:

define( 'DB_PASSWORD', 'abcd\"efgh' );

This is wrong. There should not be the \

Describe how other contributors can replicate this bug

1. create a db and a user that has " in the password. eg these sql commands:

   create database wp ;
   grant all privileges on wp.* to uwp@'localhost' identified by 'abcd"efgh';
   flush privileges;
   

2. run wp config create. This is where wp generates the wrong line

   mkdir -p foo
   cd foo
   wp core download
   wp config create --dbname=wp --dbuser=uwp --dbpass='abcd"efgh' --dbhost=localhost --dbprefix=wp_
   

Describe what you would expect as the correct outcome

The " on the DB_PASSWORD line should not be escaped. Given the above commands, the DB_PASSWORD line in wp-config.php should read:

define( 'DB_PASSWORD', 'abcd"efgh' );

Provide a possible solution

Not a solution, but I found 2 workarounds:

1. don't use " in db password, obviously
2. use wp config set afterwards. Strangely, it generates a correct line in wp-config.php.

   wp config set DB_PASSWORD 'abcd"efgh'

Thanks for the report, @schplurtz !

Feel free to submit a pull request, if you'd like. Here is some guidance on our pull request best practices.

Looks like we have used addslashes() function for all values. Is their better function to avoid this issue? Or should we implement special check for double apostrophe?

Ref: https://github.com/wp-cli/config-command/blob/main/src/Config_Command.php#L1204-L1206

	if ( is_string( $value ) ) {
		return addslashes( $value );
	}

Looks like the escaping is on purpose.

I'm glad to se that there is activity on this bug report, although I fail to see how a problem with single quote (#93) is in any way related to this problem with double quote that are escaped but should not.

PHP rules for escaping inside single quotes are so simple : only escape ' and \, that I expected the fix to be quick and easy. I'm really sorry to give you so much work and wish you good luck with all that.
