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.

php cannot connect to the oracle database

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.

How to connect to remote ORACLE database with PHP?

$dbhost = "192.168.0.111"; $dbuser = "system"; $dbpasswd = "manager "; $dbname = "192.168.0.111"; if(@$conn=OCILogon($dbuser,$ dbpasswd,$dbname)): echo "Connection successful!"; else: echo "Connection failed!"; endif; OCILogoff($conn); ?>

PHP's Current Status: A Look at Web Development TrendsApr 13, 2025 am 12:20 AM

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP vs. Other Languages: A ComparisonApr 13, 2025 am 12:19 AM

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP vs. Python: Core Features and FunctionalityApr 13, 2025 am 12:16 AM

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP: A Key Language for Web DevelopmentApr 13, 2025 am 12:08 AM

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP: The Foundation of Many WebsitesApr 13, 2025 am 12:07 AM

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

Beyond the Hype: Assessing PHP's Role TodayApr 12, 2025 am 12:17 AM

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

Explain the __invoke magic method in PHP.Apr 12, 2025 am 12:07 AM

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
