The following example PHP script, sendsms.php, can be used to send an SMS text message via NowSMS with PHP. This script can also be downloaded from https://nowsms.com/download/sendsms-php.txt.
The SendSMS function is the important part of the example. This is the function that needs to be included in your PHP script. You call this function, specifying the base URL of the NowSMS server, along with a username and password for an “SMS Users” account on the NowSMS server, plus the recipient phone number and text of the SMS message.
The SendSMS function uses these parameters to build an HTTP POST for connecting to the NowSMS server.
Additional optional parameters are supported. For additional information on NowSMS URL parameters, see https://nowsms.com/doc/submitting-sms-messages/url-parameters.
Following the SendSMS function, we show two examples of how this function might be called from within a PHP script. The first example sends an SMS text message with only the required parameters. The second example includes an extra optional parameter to illustrate how these parameters are encoded.
// This code provides an example of how you would call the SendSMS function from within // a PHP script to send a message. SendSMS('https://sample.smshosts.com/', 'username', 'password', '+44999999999', 'Test Message'); // This example adds an additional URL parameter, ReceiptRequested=Yes SendSMS('https://sample.smshosts.com/', 'username', 'password', '+44999999999', 'Test Message with delivery report', 'ReceiptRequested', 'Yes'); |
