🚀Usage

Import OTP facade

  use Eagleeye\Otp\Facades\OTP;

Static Function : get

//Facade accessor public function
public function get(String $key)
{
         //processing...
}

This will generate a OTP that valid till expire time(configured in config file),For every otp request the method response new otp string with new expire time:

• $key: The key that will be tied to the OTP.

Example

<?php

$otp = OTP::get('usertoken');

echo $otp;

// 20220317221648
// https://example/url

"267958"

Static Function : interval

//Facade accessor public function
public function interval(String $key)
{
        //processing...
}

This will generate a OTP that valid till expire time(configured in config file),for new request it will generate new otp if only previous otp with the $key expired or empty:

• $key: The key that will be tied to the OTP.

Example if otp hasnt expired

<?php

$otp = OTP::interval('usertoken');

echo $otp;

// 20220317221648
// https://example/url

array:2 [▼
  "expired" => false,
  "remaining" => "00 00:01:49" //Remaining time of expiration
]

Example if otp expired

<?php

$otp = OTP::interval('usertoken');

echo $otp;

// 20220317221648
// https://example/url

array:2 [▼
  "expired" => true,
  "otp" => "282561", //New otp
  "remaining" => "00 00:01:49" //Remaining time of expiration
]

Static Function : action

//Facade accessor public function
public function action(String $key,Callable $callback)
{
     //processing...
}

This will generate a OTP that valid till expire time(configured in config file),For every otp request the method response new otp string with new expire time. The function takes one extra callable parameter to do additional work's(SMS,EMAIL,etc..) before returning otp string:

• $key: The key that will be tied to the OTP.
• $callback: Take a callable function . Specially usefull to implement sms gateway's ,Email,etc...

Example

<?php

$otp = OTP::action('usertoken',function($otp){
    //Sms::send('+8801*******',$otp);
});

echo $otp;

// 20220317221648
// https://example/url

"267958"

Static Function : intervalaction

//Facade accessor public function
public function intervalaction(String $key,Callable $callback)
{
     //processing...
}

Same as Interval the function will generate new otp until previous one expired:

• $key: The key that will be tied to the OTP.
• $callback: Take a callable function . Specially usefull to implement sms gateway's ,Email,etc...

Example if otp hasnt expired

<?php

$otp = OTP::intervalaction('usertoken',function($otp){
    //Sms::send('+8801*******',$otp);
});

echo $otp;

// 20220317221648
// https://example/url

array:2 [▼
  "expired" => false
  "remaining" => "00 00:01:49" //Remaining time of expiration
]

Example if otp expired

<?php

$otp = OTP::intervalaction('usertoken',function($otp){
    //Sms::send('+8801*******',$otp);
});

echo $otp;

// 20220317221648
// https://example/url

array:2 [▼
  "expired" => true
  "otp" => "282561" //New otp
  "remaining" => "00 00:01:49" //Remaining time of expiration
]

Static Function : Verify

//Facade accessor public function
public function verify($key,$otp)
{
     //processing...
}

This verify function will verify otp with generated otp and expired the otp from system.

Example

<?php

$result=OTP::verify('usertoken','12345678');
echo $result;


"true"

Static Function : Readonly

//Facade accessor public function
public function readonly($options=nullable)
{
     //processing...
}

This will return a random generated string for other uses.

• $options: It takes a array as parameter to replace Configuration file parameters.

Example

<?php

$result=OTP::readonly(['prefix'=>'sn','length'=>15,'case'=>'upper','type'=>'alphabetic']);
echo $result;

// 20220331221403
// http://otp.test/
