LXXIV. Oracle 8 functions
Introduction
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 old Oracle 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 possible.
Requirements
You will need the Oracle client libraries to use this extension.
Windows users will need at least Oracle version 8.1 to use
the php_oci8.dll dll.
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 follows:
ORACLE_HOME
ORACLE_SID
LD_PRELOAD
LD_LIBRARY_PATH
NLS_LANG
ORA_NLS33
After setting up the environment variables for your webserver
user, be sure to also add the webserver user (nobody, www)
to the oracle group.
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
# make install
Please note that on some systems like UnixWare it is libthread
instead of libpthread. PHP and Apache have to be configured
with EXTRA_LIBS=-lthread.
