PHPJsonResponse

Personal PHP Class Library for standardized JSON response formatting and password validation.

Features

• ✅ Standardized JSON response structure
• ✅ Automatic data sanitization (trim strings, convert 'true'/'false' to booleans)
• ✅ Built-in password validation with preset security levels
• ✅ Multi-language support (French/English)
• ✅ Fully tested with PHPUnit

Installation

composer require alexcane/php-json-response

Usage

JsonResp Class

The main class for handling JSON responses with consistent structure.

Basic Example

use PhpJsonResp\JsonResp;

// Create instance with data
$resp = new JsonResp(['email' => '  user@example.com  ', 'active' => 'true']);

// Data is automatically sanitized
$data = $resp->getData();
// ['email' => 'user@example.com', 'active' => true]

// Add validation errors
if (empty($data['email'])) {
    $resp->addErrMsg('Email is required');
}

// Check for errors
if ($resp->isError()) {
    echo $resp->returnResponse(true); // Return as JSON string
    exit;
}

// Return successful response
echo $resp->returnResponse(true);

Response Structure

All responses follow this format:

{
    "status": "success",
    "error_msg": [],
    "data": {
        "email": "user@example.com",
        "active": true
    }
}

On error:

{
    "status": "error",
    "error_msg": ["Email is required", "Password is too short"],
    "data": {...}
}

Available Methods

// Data management
$resp->setData(['key' => 'value']);
$resp->getData();
$resp->clearData();

// Error management
$resp->addErrMsg('Error message');
$resp->setErrMsg(['Error 1', 'Error 2']);
$resp->getErrMsg();
$resp->errorCount();

// Validation
$resp->isSuccess(); // true if no errors
$resp->isError();   // true if has errors

// Custom response field
$resp->setResponse('Custom data or HTML');
$resp->getResponse();

// Return response
$resp->returnResponse();      // Returns array
$resp->returnResponse(true);  // Returns JSON string

PasswordValidator Class

Extension of JsonResp for password validation with configurable security levels.

Basic Example

use PhpJsonResp\PasswordValidator;

// Create instance (default: light config, French messages)
$validator = new PasswordValidator(['password' => $_POST['password']]);

// Validate password
if (!$validator->isValidPassword($_POST['password'])) {
    echo $validator->returnResponse(true);
    exit;
}

// Password is valid
echo $validator->returnResponse(true);

Security Levels

Light Config (default)

$validator->setLightConfig();
// - Min 6 characters
// - Requires digits
// - Uppercase optional
// - Symbols optional

Medium Config

$validator->setMediumConfig();
// - Min 10 characters
// - Requires digits
// - Requires uppercase
// - Requires symbols

Hard Config

$validator->setHardConfig();
// - Min 20 characters
// - Requires digits
// - Requires uppercase
// - Requires symbols

Custom Config

$validator->setCustomConfig(
    min: 8,
    max: 50,
    uppercase: true,
    digits: true,
    symbols: false
);

Multi-language Support

// French (default)
$validator = new PasswordValidator([], 'fr_FR');
// Error messages: "Mot de passe invalide", "6 caractères minimum", etc.

// English
$validator = new PasswordValidator([], 'en_US');
// Error messages: "Invalid Password", "at least 6 characters long", etc.

Get Generated Regex

$validator->setMediumConfig();
$regex = $validator->getRegex();
// Returns: /^(?=.*[A-Z])(?=.*\d)(?=.*[!@#$%^&*(),.?:{}|<>-_])[A-Za-z\d!@#$%^&*(),.?:{}|<>-_]{10,100}$/

Complete Validation Example

use PhpJsonResp\PasswordValidator;

$validator = new PasswordValidator($_POST, 'en_US');
$validator->setMediumConfig();

// Validate password
if (!$validator->isValidPassword($_POST['password'])) {
    header('Content-Type: application/json');
    http_response_code(400);
    echo $validator->returnResponse(true);
    exit;
}

// Password is valid, continue with registration
$user = createUser($validator->getData());

$validator->setResponse(['user_id' => $user->id]);
header('Content-Type: application/json');
echo $validator->returnResponse(true);

Response Structure

• status: string - 'error' or 'success'
• error_msg: array - List of error messages
• data: array - Validated/processed data (omitted if empty)
• response: mixed - Custom response data (omitted if empty)

Requirements

• PHP ^7.4 || ^8.0
• ext-json
