Apache refuse to communicate with MySql after downgrade php from 5.3 t

Post icon  Posted 20 January 2010 - 10:41 PM

Dear all,
This problem is also posted in the following link. I double post this since I think I need help from both the database and webserver fellow friends.

After I downgraded my php from 5.3 to 5.2, php scirpts cannot connect to MySql server. I'm not sure what part of the configurations that I need to modify.

Other than that, I can run a php scripts on my Apache sever, I can go to MySql database and do queries.

I use Apache 2.2.14, PHP 5.2.12, and MySql 5.1.41-community.

I double checked my PHP.ini and httpd.conf files and found nothing wrong. Or am I wrong?

I found out that when I executed the php script using php.exe, it ran fine as oppose through Apache server. Apache puked the following message using browser pop up:

httpd.exe - Application Error

The instrunction at "xxxxxxx" reference memory at "xxxxx". The memory could not be "read"

Click on OK to terminate the program
Click on CANCEL to debug the program

Thus the problem lies between PHP5.2 and Apache 2.2.14 when MySql is in the middle. The script is just a simple query:
$con = mysql_connect("localhost","root","xxxxx");
if (!$con)
  die('Could not connect: ' . mysql_error());

mysql_select_db("test", $con);

$result = mysql_query("SELECT * FROM name");

while($row = mysql_fetch_array($result))
  echo $row['id'] . " " . $row['name'];
  echo "<br />";


Then when I revert back PHP to 5.3, the problem's gone.

The following is myphpinfo that could help introduce the problem:

Can you log onto mysql (new install) from the command line?

Looking at the process list, is only the new mysql running?

I have experience with upgradding both PHP & mysql versions, but it was on a Unix box, not Windows.

Yes I can connect to MySQL with php 5.2

and in the process list there are mysql.exe and mysqld.exe, which saying it's running one session and a daemon.

Did you do anything on the configuration files of php, apache, and mysql? Hmm...maybe my question is not applicable since we are using different OS....
