[13-Oct-2010 09:25:39] PHP Warning: PHP Startup: oci8: Unable to initialize module
Module compiled with module API=20060613
PHP compiled with module API=20090626
These options need to match
in Unknown on line 0
STEP4:Google with "PHP Warning: PHP Startup: oci8: Unable to initialize module"
And find out the oci8 dll version is not suitable, the version is lower than php 5.3 compiled version.
STEP5:Uninstall PHP 5.3.2 from pc, and download PHP 5.3.3 , and install it with all packages.
Restart Apache: successful
Test OCI8 connection:
STEP1: create test.php file under apache htdocs folder.
STEP2: write source code into test.php file:

<?php
echo "step1 ";
$linkstr="(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = X.X.X.X)(PORT = 1521)))
(CONNECT_DATA =(SERVICE_NAME = XXXX)))";
$conn = oci_connect('user', 'password', $linkstr);
echo "step2 ";
if (!$conn) {
echo "in step1";
trigger_error("Could not connect to database", E_USER_ERROR);
}else{
echo "tina";
}
echo "step3 ";
$SQL="select * from apt_l_spdopt";
echo "step4 ";
$stid = oci_parse($conn, $SQL);
echo "step5 ";
if (!$stid){
trigger_error("Could not parse sql:".$SQL, E_USER_ERROR);
}
echo "step6 ";
oci_execute($stid);
while (($row = oci_fetch_array ($stid, OCI_ASSOC))) { // Ignore NULLs
var_dump($row);
}
echo "step7 ";
oci_free_statement($stid);
oci_close($conn);
?>
STEP5: View test.php with localhost:86/test.php, failed with message(php_errors.log)---->
[13-Oct-2010 03:38:43] PHP Warning: Module 'oci8' already loaded in Unknown on line 0

STEP6:Google with error message, and find that there are two oci8 dll exist in php.ini (php_oci8.dll &php_oci8_11g.dll),
STEP7:Uncomment php_oci8.dll, and refresh test.php. failed with message(php_errors.log)----->

[13-Oct-2010 05:13:48] PHP Warning: oci_connect(): OCIEnvNlsCreate() failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries in D:/Projects/PHP/APTUpload/jobs/include/libOracle.php on line 44

STEP8:Google with "oci_connect(): OCIEnvNlsCreate() failed", and find out that system cannot find dll library,
STEP9:Copy oci.dll,orannzsbb11.dll,oraociei11.dll,ociw32.dll into C:/WINDOWS/system32 folder, and make sure that mfc71.dll,msvcr71.dll exist in C:/WINDOWS/system32 folder.
Restart Apache : successful
Retest test.php : failed

STEP2:注册表里 /HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE 查找键 NLS_LANG,这个键由Oracle标准客户端安装创建, 值是 NA 。这个导致了 ORA-12705错误。解决方法就是修改NA为SIMPLIFIED CHINESE_CHINA.ZHS16GBK。
STEP3:refresh test.php, successfule

The whole process spend two days! it is a very good experience.
