If you've followed the instructions and you can't even connect to the DB server, welcome to the Oracle hell. Most of the information you'll find is deprecated, incomplete, not for your platform, unnecessary or just plain wrong.
Typically, you won't need at all those complicate setups you'll read about and they'll probably make things harder. I suggest you get Systernal's "Filemon" utility (for Windows, in Unix you may do with strace) and find out what exact config files and DLLs are being tried by php.exe (or httpd.exe if PHP runs as Apache module or...). Pretty often, the issue is that (e.g.) TNSNAMES.ORA does not have the correct line ending or Apache is looking for a DLL that does not even exist in your hard disc; learning that prevents you to waste time adding more and more useless environmental variables.
Goog luck.

There are several good books on PHP and Oracle available - search your favorite bookstore. There is also a free book from Oracle "The Underground PHP and Oracle Manual" that covers the OCI8 extension: http://otn.oracle.com/tech/php/pdf/underground-php-oracle-manual.pdf
(free registration for OTN required, IIRC). Disclaimer: I'm one of its authors.

re: Andrei Kubar
I was using Oracle Instant Client on Windows XP, and was getting the
PHP Startup: Unable to load dynamic library 'C:\php\ext\php_oci8.dll' - The specified module could not be found.
error at startup, even though I had done all (most?) of the PHP and Oracle setup routines.
For me it wasn't the lack of mfc*.dll files, but a simple PATH issue: in addition to defining the environment variable TNS_ADMIN, I had to include my instant client directory in my PATH.

When fetching associative arrays, use uppercase string indices. It appears the PHP OCI Library is less lenient with the field names returned by Oracle.
e.g.
echo $row['field1']; // This won't return anything.
as opposed to:
echo $row['FIELD1'];

Here's a little snipet that shows how to insert multiple clob fields. Worked for me.
$dbh = OCILogon($dst_user_name, $dst_password, $dst_db_name);
for($i = 0; $i < $src_rec_cnt; $i++) {
$query = "insert into bid (id,time,resume,experience,comments) values ('$id[$i]','$time[$i]',empty_clob(),empty_clob(),empty_clob()) returning resume,experience,comments into :resume,:experience,:comments";
$stmt = OCIParse($dbh, $query);
$clob1 = OCINewDescriptor($dbh, OCI_D_LOB);
$clob2 = OCINewDescriptor($dbh, OCI_D_LOB);
$clob3 = OCINewDescriptor($dbh, OCI_D_LOB);
OCIBindByName ($stmt, ":resume", &$clob1, -1, OCI_B_CLOB);
OCIBindByName ($stmt, ":experience", &$clob2, -1, OCI_B_CLOB);
OCIBindByName ($stmt, ":comments", &$clob3, -1, OCI_B_CLOB);
OCIExecute($stmt, OCI_DEFAULT);
@$clob1->save ($resume[$i]);
@$clob2->save ($experience[$i]);
@$clob3->save ($comments[$i]);
OCICommit($dbh);

if you feel like you have too many oracle statements clouding up your php, i came up with a function to open a connection (if necessary), parse your sql statement, and return the executed query. after you call the function, you can do whatever needs to be done. makes like so much simpler: (do whatever you want with the errors)
function execute_query($query, &$connected) {
global $ORACLE_USER, $ORACLE_PASS, $ORACLE_SID;
if(!$connected) {
$connected = @OCIPLogon($ORACLE_USER, $ORACLE_PASS, $ORACLE_SID);
if($error = OCIError()) {
die("<font color=red>ERROR!! Couldn't connect to server!</font>");
}
}
$stmt = @OCIParse($connected, $query);
if($error = OCIError($cn)) {
die("<font color=red>ERROR!! Statement syntax error!</font>");
}
@OCIExecute($stmt);
if($error = OCIError($stmt)) {
die("<font color=red>ERROR!! Could not execute statement!</font>");
}
return $stmt;
}

VERY IMPORTANT! OCIPLogon only keeps a persistent connection if you are running PHP as a module. This is particularly important to Windows users who are used to running PHP as a CGI.

Here's a clue about rowid.
Don't forget about the oracle functions:
"rowidtochar" and "chartorowid"
"select rowidtochar(rowid) as FOO from table ...."
When you want to pass the rowid in a form or link, that's
the only way to go.
