mysqli_connect() no longer accepts false/null for the socket parameter. It interprets it as an empty string and as a result fails to find the socket and therefore connect.

Previous versions used to ignore false/null and just use the hostname etc to connect.

The reason I am not just changing the call to

$db = mysqli_connect($host, $username, $password, $database);

is because this code is from PEAR::DB and this change would be quite major. See my bug:

as danielc points out: "most PHP functions gladly
accept false/null for optional string arguments without causing problems"

Reproduce code:

$db = mysqli_connect($host, $username, $password, $database, null, null);

same result with 


$db = mysqli_connect($host, $username, $password, $database, false, false);


Expected result:
a valid connection

Actual result:
following error:
Can't connect to local MySQL server through socket '' (2)

just tested with php-5.0.3. one of the bug fixes in this release, although it it not clear to me from the changelog, has fixed the bug also.

guess it is was worthwhile to record this here for people stuck on 5.0.3
