Connection Conundrum

Filed under: MySQL Gotchas,PHP Gotchas — snoyes @ 12:13 pm

Define a user like this:

GRANT ALL ON *.* TO 'myuser'@'localhost' IDENTIFIED BY 'super$ecret';

Then try a PHP script like this:

mysqli_connect("localhost", "myuser", "super$ecret");

What happens and why? How could you avoid it?

And for glory, what single line could you add that would prevent the error, without making any changes to the mysqli_connect line?


  1. $ecret = ‘$ecret’;

  2. Which is why I quote PHP strings with single quotes, not double quotes.
