[{key1: value1, key2: value2}, {key1: value1, key2: value2}, ...]

// PHP code to send a POST request with a JSON string array

// Define the JSON string array
$data = array(
    array("name" => "Alice", "age" => 25),
    array("name" => "Bob", "age" => 30),
    array("name" => "Charlie", "age" => 35)
);

// Encode the data to a JSON string
$data_json = json_encode($data);

// Set the content type and content length headers
header("Content-Type: application/json");
header("Content-Length: " . strlen($data_json));

// Create a new cURL handle
$ch = curl_init();

// Set the cURL options
curl_setopt($ch, CURLOPT_URL, "https://example.com/api");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_json);

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

// Handle any errors that occurred
if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
    // Handle the error
}

// Close the cURL handle
curl_close($ch);

// Handle the response from the server
echo $result;
