Creating a simple AI with PHP can be done using various libraries and frameworks such as TensorFlow PHP, PHP-ML, and FANN. Here's an example of creating a simple chatbot using PHP-ML:
Install PHP-ML using Composer:
Code:
composer require php-ai/php-ml
Import the required classes:
Code:
use Phpml\Classification\KNearestNeighbors;
use Phpml\Dataset\ArrayDataset;
Define the chatbot responses:
Code:
$trainingSamples = [
['Hi there!', 'greeting'],
['Hello!', 'greeting'],
['Hey!', 'greeting'],
['Goodbye!', 'farewell'],
['Bye!', 'farewell'],
['See you later!', 'farewell'],
['How are you?', 'how_are_you'],
['How have you been?', 'how_are_you'],
['What can you do?', 'what_can_you_do']
];
$trainingLabels = array_column($trainingSamples, 1);
$trainingSamples = array_column($trainingSamples, 0);
$dataset = new ArrayDataset($trainingSamples, $trainingLabels);
$classifier = new KNearestNeighbors();
$classifier->train($dataset->getSamples(), $dataset->getTargets());
Get user input and classify it using the chatbot:
Code:
$input = "Hi there!";
$predictedLabel = $classifier->predict([$input]);
switch ($predictedLabel[0]) {
case 'greeting':
echo "Hello! How can I help you?";
break;
case 'farewell':
echo "Goodbye! Have a nice day.";
break;
case 'how_are_you':
echo "I'm doing well, thank you. How can I assist you today?";
break;
case 'what_can_you_do':
echo "I can help you with general questions or concerns. Please let me know how I can assist you.";
break;
default:
echo "I'm sorry, I didn't understand that. Can you please repeat?";
break;
}
This is a very basic example of a chatbot using PHP-ML in PHP. You can expand upon this by adding more response pairs, creating more complex responses, or integrating with other libraries or APIs to add more functionality. Additionally, there are many other types of AI that you can create using PHP, such as machine learning models for image recognition, natural language processing, or predictive analytics.
