# Send an SMS Message with PHP

 Note:
Before you can get started, you need the following already set up:

- 
- [PHP](https://www.php.net/manual/en/install.php) 7.3.0 or later and a familiarity with how to create a new file.
- cURL 7.61.0 or later installed


This script will enable you to send an SMS message using PHP and the Sinch SMS API.

Steps:
1. Set up your PHP file.
2. Send your first SMS message.


## Set up your PHP file

Create a file (example: `send_sms.php`) and add the supplied sample code.

send_sms.php
<?php
$service_plan_id = "YOUR_servicePlanId";
$bearer_token = "YOUR_API_token";

//Any phone number assigned to your API
$send_from = "YOUR_Sinch_virtual_number";
//May be several, separate with a comma ,
$recipient_phone_numbers = "recipient_phone_numbers"; 
$message = "Test message to {$recipient_phone_numbers} from {$send_from}";

// Check recipient_phone_numbers for multiple numbers and make it an array.
if(stristr($recipient_phone_numbers, ',')){
  $recipient_phone_numbers = explode(',', $recipient_phone_numbers);
}else{
  $recipient_phone_numbers = [$recipient_phone_numbers];
}

// Set necessary fields to be JSON encoded
$content = [
  'to' => array_values($recipient_phone_numbers),
  'from' => $send_from,
  'body' => $message
];

$data = json_encode($content);

$ch = curl_init("https://us.sms.api.sinch.com/xms/v1/{$service_plan_id}/batches");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BEARER);
curl_setopt($ch, CURLOPT_XOAUTH2_BEARER, $bearer_token);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

$result = curl_exec($ch);

if(curl_errno($ch)) {
    echo 'Curl error: ' . curl_error($ch);
} else {
    echo $result;
}
curl_close($ch);
?>
### Fill in your parameters

1. Assign your values found in the your [Sinch Build Dashboard](https://dashboard.sinch.com/sms/api/rest) to the following parameters:



```php
$service_plan_id = "YOUR_servicePlanId";
$bearer_token = "YOUR_API_token";

//Any phone number assigned to your API
$send_from = "YOUR_Sinch_virtual_number";
//May be several, separate with a comma ,
$recipient_phone_numbers = "recipient_phone_numbers";
$message = "Test message to {$recipient_phone_numbers} from {$send_from}";
```

Double check that the region is correct on your base URL. Learn more about [regional options here](/docs/sms/api-reference#base-url).

1. Now, in the string portions in the code below, write your message:

```php
$message = "Test message to {$recipient_phone_numbers} from {$send_from}";
```
2. That's it! Just copy the rest of the script into your file, save, and you'll be sending messages in no time.


## Send your first SMS message

Execute the code and send your test SMS message with the command below:


```bash
