(PHP 5, PECL OCI8 >= 1.1.0)
oci_password_change — 修改 Oracle 用户的密码
说明 bool oci_password_change ( resource $connection , string $username , string $old_password , string $new_password ) resource oci_password_change ( string $dbname , string $username , string $old_password , string $new_password )修改用户 username 的密码。old_password 和 new_password 应分别指定旧密码和新密码。
Note: 第二种 oci_password_change() 的语法自版本 1.1（OCI8 扩展库版本）起可用。
成功时返回 TRUE， 或者在失败时返回 FALSE。
Note:
在 PHP 5.0.0 之前的版本必须使用 ocipasswordchange() 替代本函数。该函数名仍然可用，为向下兼容作为 oci_password_change() 的别名。不过其已被废弃，不推荐使用。
参数connection
An Oracle connection identifier, returned by oci_connect() or oci_pconnect().
usernameThe Oracle user name.
old_password
The old password.
new_passwordThe new password to be set.
dbnameThe database name.
返回值成功时返回 TRUE， 或者在失败时返回 FALSE。
注释Note:
Changing the password either with this function or directly in Oracle should be done carefully. This is because PHP applications may continue to successfully reuse persistent connections by authenticating with the old password. The best practice is to restart all web servers whenever the user password is changed.
Note:
If upgrading the Oracle client libraries or the database from a release prior to .2.0.3 to version .2.0.3 or higher, oci_password_change() may give the error "ORA-: invalid username/password" unless both client and server versions are upgraded at the same time.
Note: The second oci_password_change() syntax is available since OCI8 version 1.1.
Note:
In PHP versions before 5.0.0 you must use ocipasswordchange() instead. This name still can be used, it was left as alias of oci_password_change() for downwards compatability. This, however, is deprecated and not recommended.
