Here's a PHP script that uses cURL to get data from an API using the API_KEY value from the environmental variable PINECONE_API_KEY:

phpCopy code
<?php

// Get API key from environment variable
$apiKey = getenv('PINECONE_API_KEY');

// Set API URL
$url = 'https://api.example.com/data';

// Initialize cURL
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  'Authorization: Bearer ' . $apiKey,
));

// Execute cURL request
$result = curl_exec($ch);

// Check for errors
if (curl_errno($ch)) {
  echo 'Error: ' . curl_error($ch);
  exit;
}

// Close cURL
curl_close($ch);

// Output the result
echo $result;

?>

Replace https://api.example.com/data with the actual API URL you want to use, and make sure to set the appropriate headers and cURL options as needed. The Authorization header is set using the API_KEY value from the PINECONE_API_KEY environmental variable.

No worries! Here's an updated PHP script that uses the curl command you provided:

phpCopy code
<?php

// Get API key from environment variable
$apiKey = getenv('YOUR_API_KEY');

// Set API URL
$url = 'https://controller.us-east1-gcp.pinecone.io/actions/whoami';

// Initialize cURL
$ch = curl_init();

// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
  'Api-Key: ' . $apiKey,
));

// Execute cURL request
$response = curl_exec($ch);

// Check for errors
if (curl_errno($ch)) {
  echo 'Error: ' . curl_error($ch);
  exit;
}

// Close cURL
curl_close($ch);

// Output the response
echo $response;

?>

Make sure to replace YOUR_API_KEY with the actual API key value you want to use, and set the appropriate cURL options and headers as needed. The Api-Key header is set using the apiKey variable, which is retrieved from the YOUR_API_KEY environmental variable.

Here's a PHP function that takes in the specified variables and performs the curl call:

phpCopy code
function pineconeQuery($project, $apiKey, $vector, $topK, $includeValues) {
  // Set API URL
  $url = "https://hello-pinecone-$project.svc.us-eastl-gcp.pinecone.io/query";

  // Set request data
  $requestData = array(
    'vector' => $vector,
    'topK' => $topK,
    'includeValues' => $includeValues
  );
  $jsonData = json_encode($requestData);

  // Initialize cURL
  $ch = curl_init();

  // Set cURL options
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Api-Key: ' . $apiKey,
    'Content-Type: application/json'
  ));
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);

  // Execute cURL request
  $response = curl_exec($ch);

  // Check for errors
  if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
    exit;
  }

  // Close cURL
  curl_close($ch);

  // Return the response
  return $response;
}

You can call this function by passing in the necessary variables:

phpCopy code
$output = pineconeQuery('YOUR_PROJECT', 'YOUR_API_KEY', [0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3], 3, true);

Replace YOUR_PROJECT and YOUR_API_KEY with the actual project name and API key value you want to use, and set the vector, topK, and includeValues variables to the desired values. The function will return the output from the curl call as a string.

Yes, you are correct! When concatenating a variable inside a string in PHP, you need to use the concatenation operator (.) to combine the string and the variable. So the line should be:

bashCopy code
$url = "https://hello-pinecone-" . $project . ".svc.us-eastl-gcp.pinecone.io/query";

Thank you for catching that!
