如何在PHP中使用Oracle函数

<?php
    //数据库用户名
    $user = "用户名";
    //数据库密码
    $passWord = "密码";
    //数据库主机名和端口号
    $db = "(DESCRIPTioN=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=主机名)(PORT=端口号)))(CONNECT_DATA=(SID=服务名)))";
?>

<?php
    //连接数据库
    $conn = ocilogon($user, $password, $db);
?>

<?php
    //查询SQL语句
    $sql = "SELECT name, age FROM person WHERE age > ?";
    
    //调用ociparse函数
    $stmt = ociparse($conn, $sql);
    
    //设置参数值
    $age = 18;
    ocibindbyname($stmt, ":p1", $age);
    
    //执行SQL语句
    ociexecute($stmt);
?>

<?php
    //插入SQL语句
    $sql = "INSERT INTO person(name, age) VALUES (?, ?)";
    
    //调用ociparse函数
    $stmt = ociparse($conn, $sql);
    
    //设置参数值
    $name = "张三";
    $age = 20;
    ocibindbyname($stmt, ":p1", $name);
    ocibindbyname($stmt, ":p2", $age);
    
    //执行SQL语句
    ociexecute($stmt);
?>

<?php
    //更新SQL语句
    $sql = "UPDATE person SET age = ? WHERE name = ?";
    
    //调用ociparse函数
    $stmt = ociparse($conn, $sql);
    
    //设置参数值
    $name = "张三";
    $age = 25;
    ocibindbyname($stmt, ":p1", $age);
    ocibindbyname($stmt, ":p2", $name);
    
    //执行SQL语句
    ociexecute($stmt);
?>

<?php
    //删除SQL语句
    $sql = "DELETE FROM person WHERE name = ?";
    
    //调用ociparse函数
    $stmt = ociparse($conn, $sql);
    
    //设置参数值
    $name = "张三";
    ocibindbyname($stmt, ":p1", $name);
    
    //执行SQL语句
    ociexecute($stmt);
?>

<?php
    //关闭连接
    ocilogoff($conn);
?>
