PHP Linux脚本编程实战：实现网络请求与处理

<?php
$url = "https://api.example.com/data";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close($ch);

// 处理返回的数据
$data = JSON_decode($response, true);

// 输出处理后的数据
print_r($data);
?>

<?php
$ftp_server = "ftp.example.com";
$ftp_username = "username";
$ftp_passWord = "password";
$file = "path/to/local/file.jpg";
$remote_file = "path/to/remote/file.jpg";

// 建立FTP连接
$conn_id = ftp_connect($ftp_server);

// 登录FTP
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);

// 检查是否成功登录
if (!$conn_id || !$login_result) {
    die("FTP登录失败！");
}

// 上传文件
if (ftp_put($conn_id, $remote_file, $file, FTP_BINARY)) {
    echo "文件上传成功！";
} else {
    echo "文件上传失败！";
}

// 关闭FTP连接
ftp_close($conn_id);
?>

<?php
$json_data = '{"name":"John","age":30,"city":"New York"}';

// 解析JSON数据
$data = json_decode($json_data, true);

// 输出解析后的数据
echo "Name: " . $data['name'] . "<br>";
echo "Age: " . $data['age'] . "<br>";
echo "City: " . $data['city'] . "<br>";
?>
