用PHP调用Oracle存储过程_PHP

从开始学习PHP就来喜悦国际村,好几个月了,学到不少东西,自己写了个例子希望有点用处。

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。

这是偶第一次写文章(以前都是发水贴),希望大家多多斧正!



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
";

?>

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
