LXXVIII. Oracle 8 functions
These functions allow you to access Oracle9, Oracle8 and Oracle7 databases.
It uses the Oracle Call Interface (OCI).
This extension is more flexible than the
extension. It supports binding of global and local PHP variables
to Oracle placeholders, has full LOB, FILE and ROWID support
and allows you to use user-supplied define variables.
You are recommended to use this extension instead of
old Oracle extension where
You will need the Oracle client libraries to use this extension.
Windows users will need at least Oracle version 8.1 to use the
Before using this extension, make sure that you have set up your
Oracle environment variables properly for the Oracle user, as well
as your web daemon user. The variables you might need to set are as
After setting up the environment variables for your webserver user,
be sure to also add the webserver user (nobody, www) to the oracle
If your webserver doesn't start or crashes at startup:
Check that Apache is linked with the pthread library:
# ldd /www/apache/bin/httpd
libpthread.so.0 => /lib/libpthread.so.0 (0x4001c000)
libm.so.6 => /lib/libm.so.6 (0x4002f000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0x4004c000)
libdl.so.2 => /lib/libdl.so.2 (0x4007a000)
libc.so.6 => /lib/libc.so.6 (0x4007e000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
If the libpthread is not listed you have to reinstall Apache:
# cd /usr/src/apache_1.3.xx
# make clean
# LIBS=-lpthread ./config.status
# make install
Please note that on some systems like UnixWare it is libthread
instead of libpthread. PHP and Apache have to be configured
You have to compile PHP with the option
--with-oci8[=DIR], where DIR defaults to
your environment variable ORACLE_HOME.
This extension has no configuration directives defined in php.ini.
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
Example 1. OCI Hints
// by sergo at bacup dot ru
// Use option: OCI_DEFAULT for execute command to delay execution
// for retrieve data use (after fetch):
$result = OCIResult($stmt, $n);
if (is_object($result)) $result = $result->load();
// For INSERT or UPDATE statement use:
$sql = "insert into table (field1, field2) values (field1 = 'value',
field2 = empty_clob()) returning field2 into :field2";
$clob = OCINewDescriptor($conn, OCI_D_LOB);
OCIBindByName($stmt, ":field2", &$clob, -1, OCI_B_CLOB);
You can easily access stored procedures in the same way as you
would from the commands line.
Example 2. Using Stored Procedures
// by webmaster at remoterealty dot com
$sth = OCIParse($dbh, "begin sp_newaddress( :address_id, '$firstname',
'$lastname', '$company', '$address1', '$address2', '$city', '$state',
'$postalcode', '$country', :error_code );end;");
// This calls stored procedure sp_newaddress, with :address_id being an
// in/out variable and :error_code being an out variable.
// Then you do the binding:
OCIBindByName($sth, ":address_id", $addr_id, 10);
OCIBindByName($sth, ":error_code", $errorcode, 10);
