PHP中Abstract API手机号码验证的正确实践

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://phonevalidation.abstractapi.com/v1/?api_key=my_api&phone=14152007986');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // 确保CURL返回响应而不是直接输出
$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response, true); // 将JSON解码为关联数组
$check = (string)$data; // 错误：将整个数组转换为字符串，可能得到"Array"或空字符串

if (strpos($check, 'true') == true) // 问题1：0 == true 为 false
{
    echo "PhoneNo is valid";
}
if (strpos($check, 'false') == false) // 问题2：strpos未找到时返回false，false == false 为 true
{
    echo "PhoneNo is invalid";
}

// 假设 $response 确实是包含 "true" 或 "false" 的字符串
// 但正如前面所说，直接将 $data 数组转换为字符串是错误的实践
// 此处仅为演示 strpos 的正确用法
$mock_response_string = '{"valid":true,"number":"14152007986"}'; // 假设的原始JSON字符串
$check_string = $mock_response_string; // 在这个场景下，我们假设 $check_string 是一个有效的JSON字符串
