Use ASCII case conversion instead of locale-dependent case conversion in the following places: * grapheme_stripos() and grapheme_strripos() in the "fast" path * ldap_get_entries() * oci_pconnect() for case folding of parameters when constructing a key into the connection or session pool * SoapClient: case folding of function names * get_meta_tags(): case conversion of property names * http stream wrapper: header names * phpinfo(): anchor names * php_verror(): docref URLs * rfc1867.c: Content-Type boundary parameter name * streams.c: stream protocol names Using locale-dependent case folding for these cases is either unnecessary or actively incorrect. These functions could have misbehaved when used with certain locales (e.g. Turkish). Closes GH-7511.
The OCI8 Extension
Use the OCI8 extension to access Oracle Database.
Documentation is at https://www.php.net/oci8
Use pecl install oci8 to install for PHP 8.
Use pecl install oci8-2.2.0 to install for PHP 7.
Use pecl install oci8-2.0.12 to install for PHP 5.2 - PHP 5.6.
Use pecl install oci8-1.4.10 to install for PHP 4.3.9 - PHP 5.1.
The OCI8 extension can be linked with Oracle client libraries from Oracle Database 10.2 or later. These libraries are found in your database installation, or in the free Oracle Instant Client from https://www.oracle.com/database/technologies/instant-client.html Install the 'Basic' or 'Basic Light' Instant Client package. If building from source, then also install the SDK package.
Oracle's standard cross-version connectivity applies. For example, PHP OCI8 linked with Instant Client 19c can connect to Oracle Database 11.2 onward. See Oracle's note "Oracle Client / Server Interoperability Support" (ID 207303.1) for details.
