PHP connects to Oracle database under Linux, linuxoracle

Installation steps:

1. Install oracle-instantclient

Download address: http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Download oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm

Download
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm

Place it in the /usr/packages/ directory

# rmp -ivh oracle-instantclient*

The /usr/lib/oracle/11.2/client/lib/ directory will be generated at this time

*Note: Download the corresponding database version

2. Modify the /etc/ld.so.conf configuration file

Add some content:

/usr/lib/oracle/11.2/client/lib/

Execute command # ldconfig

3. Install oci8

Download the latest oci8 components

Download address: http://pecl.php.net/package/oci8

Download oci-2.0.8.tgz

Place it in the /usr/packages/ directory

# tar -xvzf oci-2.0.8.tgz

# cd oci-2.0.8

# /usr/local/php/bin/phpize （用phpize生成configure配置文件）

# ./configure --with-php-config=/usr/local/php/bin/php-config --with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client/lib

# make && make install

After success, you will be informed that oci8.so has been successfully placed in the following directory

4. Configure PHP to support OCI extension

Modify php configuration file

# vi /usr/local/php/lib/php.ini file

Append the following content after the extension item

extension=oci8.so

5. Restart the Apache service test

# apachectl restart

Use the probe function phpinfo() to check whether the extension is enabled. If the following picture appears, it means the extension is enabled

6. Test database connection

Write oracle.php in the site root directory

The code is as follows:

<&#63;php
  $conn = ocilogon('test','test','192.168.23.131:1521/dev');
  if (!$conn)
  {
    $Error = oci_error();
    print htmlentities($Error['message']);
    exit;
  }
  else
  {
    echo "Connected Oracle Successd!"."<br>";
    ocilogoff($conn);
  }
&#63;>

Enter http://192.168.1.131/oracle.php in the browser address bar

Explanation: 192.168.1.131 is the server address, which directly points to the site and directory of the server Apache.

Display Connected Oracle Successd! indicates that the database connection is successful.

Please explain the specific meaning of "not easy to use". It needs to be analyzed based on the specific situation. If it prompts that there is no such function, then you should use ocilogon to replace this function.
