How to use the logging and auditing functions of the Oracle database in PHP

Oracle database provides powerful logging and auditing functions that can record and track all operations of the database to ensure the security and traceability of the database. . This article will introduce how to use the logging and auditing functions of Oracle database in PHP and give corresponding code examples.

1. Enable the logging and auditing functions of the Oracle database
To use the logging and auditing functions of the Oracle database, you first need to ensure that the corresponding configuration has been enabled in the database. It can be enabled through the following steps:

1. In the Oracle database, log in with the system account and execute the following command:

   ALTER SYSTEM SET AUDIT_TRAIL='DB,EXTENDED' SCOPE =SPFILE;

   This command will enable the database level audit function and write the audit log to the database's own audit table.

2. Restart the database to make the configuration take effect.

2. Using the logging and auditing functions of the Oracle database in PHP
To use the logging and auditing functions of the Oracle database in PHP, you need to use the Oracle extension package. You can configure the PHP environment through the following steps:

1. In the php.ini file, find the following line and uncomment it:

   ;extension=oci8_12c

   Change it to:

   extension=oci8_12c

   Save the file and restart the web server to make the configuration take effect.

2. To use the logging and auditing functions of the Oracle database in PHP code, you need to connect to the database first. You can connect to the database through the following code example:

   $conn = oci_connect('username', 'password', 'hostname/service_name');
   if (!$conn ) {

   d06056c6b2fd7ea4bfad9f92153e7af2

   }

   oci_free_statement($stmt);
   oci_close($conn);
   ? >

   In the above code, the SQL statement SELECT is used to query the audit records within the specified time period from the audit table and sort them according to the timestamp. Then use the oci_fetch_assoc function to iterate through the result set and output the values ​​of the relevant fields.

   In practical applications, query conditions and analysis methods can be customized according to specific needs to meet actual audit needs.

   Summary:
   This article introduces how to use the logging and auditing functions of the Oracle database in PHP, and gives corresponding code examples. By enabling the audit function of the database and recording and querying audit logs in PHP code, the security and traceability of database operations can be increased. We hope that readers can implement their own logging and auditing functions based on the methods and examples provided in this article.
