How to convert "array" to string using "input" value

To convert the array to a string using the input value in PHP, you can use the json_encode function to convert the array into a JSON string, which is a common and easy-to-read format. Here's how you can modify your PHP code to achieve this:

'+001822901920', 'body'=>'Hello World!'),
  array('to'=>'+001822901922', 'body'=>'Hello World!')
);

$input = json_encode($messages);
echo $input;
?>

The fully code is here, I would like to insert value into two input (one for number and another one for message). Than using "array".

$username = 'yes';
$password = 'of_course';
$messages = array(
  array('to'=>'+243822901920', 'body'=>'Hello World!'),
  array('to'=>'+243822901922', 'body'=>'Hello World!')
);  

$result = send_message( json_encode($messages), 'https://api.x.com/v1/messages?auto-unicode=true&longMessageMaxParts=30', $username, $password );

if ($result['http_status'] != 201) {
  print "Error sending: " . ($result['error'] ? $result['error'] : "HTTP status ".$result['http_status']."; Response was " .$result['server_response']);
} else {
  print "Response " . $result['server_response'];
  // Use json_decode($result['server_response']) to work with the response further
}

function send_message ( $post_body, $url, $username, $password) {
  $ch = curl_init( );
  $headers = array(
  'Content-Type:application/json',
  'Authorization:Basic '. base64_encode("$username:$password")
  );
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt ( $ch, CURLOPT_URL, $url );
  curl_setopt ( $ch, CURLOPT_POST, 1 );
  curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt ( $ch, CURLOPT_POSTFIELDS, $post_body );
  // Allow cUrl functions 20 seconds to execute
  curl_setopt ( $ch, CURLOPT_TIMEOUT, 20 );
  // Wait 10 seconds while trying to connect
  curl_setopt ( $ch, CURLOPT_CONNECTTIMEOUT, 10 );
  $output = array();
  $output['server_response'] = curl_exec( $ch );
  $curl_info = curl_getinfo( $ch );
  $output['http_status'] = $curl_info[ 'http_code' ];
  $output['error'] = curl_error($ch);
  curl_close( $ch );
  return $output;
} 
?>        

An input value from the user (assuming it's passed via GET method), then retrieves the corresponding message from the $messages array and converts it to a string format.
 

$username = 'yes';
$password = 'of_course';
$input = $_GET['input']; // Assuming input is provided via GET method

// Assuming $input is a valid index in $messages array
$messages = array(
  array('to'=>'+001822901920', 'body'=>'Hello World!'),
  array('to'=>'+001822901922', 'body'=>'Hello World!')
);

if (isset($messages[$input])) {
    $message = $messages[$input];
    $stringMessage = "To: " . $message['to'] . "\nBody: " . $message['body'];
    echo $stringMessage;
} else {
    echo "Invalid input index";
}
