write a php script that uses the following curl command and displays the output. It gets the API\_KEY value from environmental variable PINECONE\_API\_KEY
 Here's a PHP script that uses cURL to make a request to an API using the API key from the environmental variable `PINECONE_API_KEY` and displays the output:

```php
<?php

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

// Set the URL for the API request
$url = 'https://api.example.com/data'; // Replace with the actual API endpoint

// Initialize cURL
$ch = curl_init();

// Set the cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: API_KEY ' . $apiKey,
    'Content-Type: application/json',
));

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

// Check for any cURL errors
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
} else {
    // Display the API response
    echo $response;
}

// Close the cURL session
curl_
  Sure! Here is an example of a PHP script that uses the `curl` command to make an API request and displays the output:
```
<?php

// Get the API_KEY value from the environmental variable PINECONE_API_KEY
$apiKey = getenv('PINECONE_API_KEY');

// Use the API_KEY to make a request to the API endpoint
$response = curl_setopt_array($ch, array(
    CURLOPT_URL => 'https://api.pinecone.io/v1/users',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => array(
        'Authorization: Bearer '. $apiKey
    )
));

// Display the response
echo $response;

// Close the cURL session
curl_close($ch);
```
In this script, we first get the `API_KEY` value from the environmental variable `PINECONE_API_KEY`. We then use this value to make a request to the API endpoint using the `curl_setopt_array` function. This function allows us to set various options for the cURL session, such as the URL, return type, and HTTP headers. In this case, we set the `Authorization` header to include the `Bearer` token for the API key.
