用PHP调用Oracle存储过程
PHP程序访问数据库,完全可以使用存储过程,有人认为使用存储过程便于维护
不过仁者见仁,智者见智,在这个问题上,偶认为使用存储过程意味着必须要DBA和开发人员更紧密配合,如果其中一方更变,则显然难以维护。
但是使用存储过程至少有两个最明显的优点:速度和效率。
使用存储过程的速度显然更快。
在效率上,如果应用一次需要做一系列SQL操作,则需要往返于PHP与ORACLE,不如把该应用直接放到数据库方以减少往返次数,增加效率。
但是在INTERNET应用上,速度是极度重要的,所以很有必要使用存储过程。
偶也是使用PHP调用存储过程不久,做了下面这个列子。
代码:--------------------------------------------------------------------------------
//建立一个TEST表
CREATE TABLE TEST (
ID NUMBER(16) NOT NULL,
NAME VARCHAR2(30) NOT NULL,
PRIMARY KEY (ID)
);
//插入一条数据
INSERT INTO TEST VALUES (5, 'PHP_BOOK');
//建立一个存储过程
CREATE OR REPLACE PROCEDURE PROC_TEST (
p_id IN OUT NUMBER,
p_name OUT VARCHAR2
) AS
BEGIN
SELECT NAME INTO p_name
FROM TEST
WHERE ID = 5;
END PROC_TEST;
/
--------------------------------------------------------------------------------
PHP代码:--------------------------------------------------------------------------------
//建立数据库连接
$user = "scott"; //数据库用户名
$password = "tiger"; //密码
$conn_str = "tnsname"; //连接串(cstr : Connection_STRing)
$remote = true //是否远程连接
if ($remote) {
$conn = OCILogon($user, $password, $conn_str);
}
else {
$conn = OCILogon($user, $password);
}
//设定绑定
$id = 5; //准备用以绑定的php变量 id
$name = ""; //准备用以绑定的php变量 name
/** 调用存储过程的sql语句(sql_sp : SQL_StoreProcedure)
* 语法:
* BEGIN 存储过程名([[:]参数]); END;
* 加上冒号表示该参数是一个位置
**/
$sql_sp = "BEGIN PROC_TEST(:id, :name); END;";
//Parse
$stmt = OCIParse($conn, $sql_sp);
//执行绑定
OCIBindByName($stmt, ":id", $id, 16); //参数说明:绑定php变量$id到位置:id,并设定绑定长度16位
OCIBindByName($stmt, ":name", $name, 30);
//Execute
OCIExecute($stmt);
//结果
echo "name is : $name
";
?>

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.
