These functions allow you to access Oracle8 and Oracle7 databases. It uses the Oracle8 Call-Interface (OCI8)
This extension is more flexible than the standard 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 will need the Oracle8 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:
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:
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.
You have to compile PHP with the option --with-oci8[=DIR], where DIR defaults to your environment variable ORACLE_HOME.
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.

You can easily access stored procedures in the same way as you would from the commands line.
