PHP+ORACLE Connection error

[nehal_b_s]

hi friends .
i am trying to connect to oracle database with php in win32.
following is the error :

Fatal error: Call to undefined function: ocilogon() in e:\inetpub\wwwroot\orcl.php on line 2
PHP Warning: Unknown(): Unable to load dynamic library './extensions/php_oci8.dll' - The specified procedure could not be found. in Unknown on line 0

php code is as follows:

<?php
if ($c=OCILogon("scott", "tiger", "")) {
echo "Successfully connected to Oracle.\n";
OCILogoff($c);
} else {
$err = OCIError();
echo "Oracle Connect Error " . $err[text];
}
?>

i have uncommented both the extension files :
php_oci8.dll
php_oracle.dll

pl. share ur experience with me.
regards,
nehal

What's wrong?

You may have wrong version of oci.dll in your PATH environment.

How to solve it?

First choice,You need to put the correct verion of oci.dll (8.1.7) in your currrent PATH environment.

Second choice,You can copy the correct version of oci.dll from $ORACLE_HOME/bin/oci.dll (8.1.7) in to APACHE Home.

I've used the second choice because I don’t need to change path environment that can take effect to other program that use differenct oci.dll version.
