ID card verification and information identification in PHP and mini programs

In modern society, ID cards are an important identity credential that everyone must have. However, in the fields of network application development, mini program development, etc., for identity Certificate verification and information identification are even more essential functions. This article will introduce how to use PHP and small programs to implement ID card verification and information identification, and give corresponding code examples.

1. ID card verification

ID card verification refers to judging whether an ID number is legal and valid through the verification rules of the ID number. Common verification rules include the following aspects:
1. Length verification: ID card numbers are generally 18 digits, and a few are 15 digits.
2. Area code verification: The first 6 digits of the ID number are the area code, which need to match the encoding rules.
3. Birthday verification: The 7th to 12th digits of the ID number are the year, month and day of birth, and need to be verified for validity.
4. Sequence code verification: The 13th to 17th digits of the ID card number are sequence codes, which are used to distinguish different people with the same date of birth in the same area.
5. Check code verification: The last digit of the ID number is the check code, which is used to verify whether the first 17 digits are correct.

The following is a simple PHP function example for verification of ID number:

function verifyIdCard($idCard)
{
    // 长度校验
    $len = strlen($idCard);
    if ($len != 15 && $len != 18) {
        return false;
    }

    // 地区码校验
    // 具体的编码规则可参考国家标准 GB/T 2260
    $areaCode = substr($idCard, 0, 6);
    if (!checkAreaCode($areaCode)) {
        return false;
    }

    // 生日校验
    $birth = ($len == 15) ? '19' . substr($idCard, 6, 6) : substr($idCard, 6, 8);
    if (!checkBirth($birth)) {
        return false;
    }

    // 顺序码校验
    $sequenceCode = substr($idCard, -4, 3);
    if (!checkSequenceCode($sequenceCode)) {
        return false;
    }

    // 校验码校验
    $verifyCode = substr($idCard, -1);
    if (!checkVerifyCode($idCard, $verifyCode)) {
        return false;
    }

    return true;
}

checkAreaCode, checkBirth, checkSequenceCode, checkVerifyCode functions need to be written according to specific requirements. By calling the verifyIdCard function, we can determine whether an ID number is valid.

2. ID card information identification

ID card information identification refers to automatically identifying the corresponding ID number, name, gender, date of birth, ethnicity and other information through the ID number. . We can realize the identification of ID card information through public APIs, SDKs, etc.

The following is a sample code of a small program, which uses Tencent Cloud's OCR (Optical Character Recognition) service to identify ID cards:

wx.chooseImage({
    count: 1,
    sizeType: ['compressed'],
    sourceType: ['album', 'camera'],
    success(res) {
        const imgPath = res.tempFilePaths[0];
        wx.uploadFile({
            url: 'https://api.weixin.qq.com/cv/ocr/idcard',
            filePath: imgPath,
            name: 'image',
            formData: {
                access_token: ACCESS_TOKEN,
                type: 'photo',
                openid: OPENID,
            },
            success(res) {
                const result = JSON.parse(res.data);
                console.log(result.item_list[0].value);
                // 可以根据识别结果,提取出身份证的各种信息
            },
        });
    },
});

In the above code, we pass wx.chooseImage Select an image, and then upload the image to Tencent Cloud's OCR service for identification through the wx.uploadFile method. Tencent Cloud will return the recognition results, and we can extract various information about the ID card based on the results.

3. Summary

Through the above example code, we can realize the verification and information identification of ID cards. ID card verification can ensure the validity of the ID number entered by the user, while ID card information recognition can automatically extract relevant information about the ID card to improve development efficiency. This is very important for various network application development, small program development and other scenarios.

However, in order to protect users' privacy and information security, we must follow relevant laws and regulations during development to ensure that the privacy of ID card information is not leaked. At the same time, you should also use ID card information identification services provided by trustworthy service providers.

By learning and mastering the methods of ID card verification and information identification, we can provide users with more secure and convenient services, and contribute to the user experience and functional improvement of the application.
