Description:
------------
PHP has been installed with "with-mysql=/usr/local/mysql".

PHP 4.3.8
Mysql 4.0.15
iPlanet 6.1

It was working well with PHP 4.3.4 before we upgrade.

Once we upgraded PHP to 4.3.8, we got "mysql_connect(): Can't connect to MySQL server..." when trying to open a page from the webserver. The command-line PHP was still working correctly.

We recompiled PHP with "with-mysql" only (built-in MySQL) and it all started working ok.

Reproduce code:
---------------
<html>
<body>
<?php

$hostname = 'hostname';
$user = 'root';
$passwd = 'password';
$database_name = 'mysql';
$error_connection = 'Cannot connect to MySQL';
$error_db = "Invalid database name ($database_name)";

if (!($connection = @ mysql_connect($hostname, $user, $passwd)))
        die("$error_connection");
if (!(mysql_select_db($database_name, $connection)))
        die("$error_db");

$query = "show tables;";
if (!($result = mysql_query ($query, $connection)))
        die("error");
while ($row = @ mysql_fetch_array($result)) {
 echo "$row[0]<br>";
}
?>
</body>
</html>

Expected result:
----------------
The list of tables should print on the screen if ran from the webserver:

columns_priv
db
func
host
tables_priv
user

If ran from the command line:

nrn1# /usr/local/php/bin/php test_PHP_mysql.php
<html>
<body>
columns_priv<br>db<br>func<br>host<br>tables_priv<br>user<br></body>
</html>
nrn1#

Actual result:
--------------
From the webserver:

Cannot connect to MySQL

From the command line:

nrn1# /usr/local/php/bin/php test_PHP_mysql.php
<html>
<body>
columns_priv<br>db<br>func<br>host<br>tables_priv<br>user<br></body>
</html>
nrn1#

How about to remove the warning suppress in mysql_connect 
to see what failed?
 [2004-07-26 20:16 UTC] chcaron at nrcan dot gc dot ca 
We are on a production server, so I can't go back to a state where PHP is not working, so here's the original output without warnings that I received from a client when he discovered it was not working (from the webserver):

Warning: mysql_connect(): Can't connect to MySQL server on 'servername' (2) in /directory/where/the/script.php on line 10

Please note it did work from the command line (e.g. /usr/local/php/bin/php script.php), so MySQL is correctly configured. Also, it was working from the webserver just before we upgrade PHP from 4.3.4 to 4.3.8.

I'll try to reproduce the bug on a developement server.

We just upgraded a server from 4.3.6 (using bundled MySQL) to 4.3.8 (using external MySQL 3.23.53) with iPlanet 4.1 and 6.1 and did not notice any problems. Of course, it's not exactly the same environment that produced the original bug.
