A Practical guide to use Google Bard APIs in PHP – The Heartbeat of Web Development

As you know, Google Bard is a powerful AI tool that can be used for a variety of tasks, including generating text, translating languages, and answering questions in an informative way. Bard is still under development, but it has already learned to perform many kinds of tasks, including:

Following instructions and completing requests thoughtfully.
Using knowledge to answer questions in a comprehensive and informative way, even if they are open ended, challenging, or strange.
Generating different creative text formats of text content, like poems, code, scripts, musical pieces, email, letters, etc.

Native PHP developers can use Bard to enhance their applications in a variety of ways. For example, Bard can be used to:

Generate personalized content for users, such as product recommendations, news articles, or blog posts just like ChatGPT
Answer customer questions in a more comprehensive and informative way.
Translate content into multiple languages for a global audience.
Generate creative content, such as poems, code, or scripts.

To use Bard with Native PHP, developers will need to create a Google Cloud Platform project and enable the Bard API service. Next, they will need to generate API credentials (API Key) for authentication.

Prerequisites to use Google Bard APIs

1- Create a Free GCP (Google Cloud Platform) account at https://console.cloud.google.com/
2- Visit https://makersuite.google.com/ and create your Generative AI key to use in your code for authentication purposes.

cURL Example
The following example shows how to use the Bard in Curl to generate a simple text response:

curl \
-H 'Content-Type: application/json' \
-d '{ "prompt": { "text": "Write a story about a magic backpack"} }' \
"https://generativelanguage.googleapis.com/v1beta3/models/text-bison-001:generateText?key=YOUR_API_KEY"

PHP Example using cURL
Here is an example of a simple PHP script that uses cURL to generate a text response from the Generative AI API:

<?php

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://generativelanguage.googleapis.com/v1beta3/models/text-bison-001:generateText?key=YOUR_API_KEY',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS =>'{ "prompt": { "text": "Write a story about a magic backpack"} }',
  CURLOPT_HTTPHEADER => array(
    'Content-Type: application/json'
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;

You can use the same basic approach to make any other type of request to the Generative AI API. For example, you could use it to translate text, generate different creative text formats, or answer questions in an informative way.

As AI technology continues to develop, we can expect to see even more powerful and innovative ways to use AI in PHP applications. Google Generative AI and ChatGPT are just the beginning.
