I am doing a project of using OTP for the login of the websites, I have created a button named "Generate" once clicked it will create an OTP and send an SMS via HTTP gateway, then it stores the password in the database.

My code to create an OTP and save in DB:

    $string = 'abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $string_shuffled = str_shuffle($string);
    $password = substr($string_shuffled, 1, 7);

    $password = base64_encode($password);
    $query = mysql_query("UPDATE user_login SET password='".$password."' WHERE username = 'ajai sandy' ");
    $qry_run = mysql_query($query);

Now I need to place this code of SMS API: 456&sid=senderid&msg=test%20message&fl=0 

The thing is the 5th line of code generates the OTP, then I need to place my SMS API after this so that it could send the password to the mobile, then it should encrypt the password which is on the 6th line and then saves in the database.

Am not sure how to perform this action in sequence and don't know where to place the code

Try this.

    $string = 'abcdefghijklmnopqrstuvwxyz0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $string_shuffled = str_shuffle($string);
    $password = substr($string_shuffled, 1, 7);


    $password = base64_encode($password);
    $query = mysql_query("UPDATE user_login SET password='".$password."' WHERE username = 'ajai sandy' ");
    $qry_run = mysql_query($query);

  • @krishna am having both the codes but am not sure how to place them with one another .. I need to generate an OTP then send the password to mobile via sms . Then save the password in db under encryption
  • it says "failed to open stream" , the url is suppose to send a request to the server ""
  • I took the SMS api link and pasted in my browser url bar and hit the period key , its working like a charm . But when placed inside the coding its generating the error " failed to open stream"
  • use like this.. echo file_get_contents("$password%20message&fl=0");
  • On which website did you implemented it ? I hope it is not a too critical service. It doesn't look very secure to discard duplicates letters in OTP and limit it to 7 chars... Lastly, why base64 encode a string which is not binary ? It adds no extra security layer.
  • I paste it, but it is Failed#Invalid Login.
