I know that this one is common but I have reviewed all related posts on stackoverflow and can't find a solution to this problem. I am using the latest MAMP. I have a mysql database which I set up in the command line using the mysql which came with MAMP. I have a user named "phpuser" whose password is "phpuser". I have checked this many times and can log in with that user and password by the command line. Here is my code. It is straight out of the intro tutorial here (http://www.w3schools.com/php/php_mysql_connect.asp): connect_error) { die("Connection failed: " . $conn->connect_error); } echo "Connected successfully"; ?> When I run it using the most recent MAMP php version, I get this error: Nicks-MacBook-Pro:howdy Nick$ /Applications/MAMP/bin/php/php5.6.2/bin/php first_db.php Notice: Use of undefined constant “phpuser” - assumed '“phpuser”' in /Applications/MAMP/htdocs/howdy/first_db.php on line 3 Notice: Use of undefined constant “phpuser” - assumed '“phpuser”' in /Applications/MAMP/htdocs/howdy/first_db.php on line 4 Warning: mysqli::mysqli(): (28000/1045): Access denied for user '“phpuser”'@'localhost' (using password: YES) in /Applications/MAMP/htdocs/howdy/first_db.php on line 7 Connection failed: Access denied for user '“phpuser”'@'localhost' (using password: YES) I've tried running it with the default php version and then I get a different error: Nicks-MacBook-Pro:howdy Nick$ php first_db.php Warning: mysqli::mysqli(): (HY000/1045): Access denied for user '“phpuser”'@'localhost' (using password: YES) in /Applications/MAMP/htdocs/howdy/first_db.php on line 7 Connection failed: Access denied for user '“phpuser”'@'localhost' (using password: YES) I've tried it with 127.0.1.1 instead of local host and that doesn't work either.
