The following small series for you to share a ajax+php implementation of no-refresh verification of mobile phone number instances, with a good reference value, I hope to be helpful to everyone. Let's take a look at it with a little knitting.
A simple no-refresh verification phone number is registered:
Client implementations:
<! DOCTYPE html>Server-side implementations:
<?php$con = Mysqli_connect (' localhost ', ' username ', ' password '), if (! $con) {die (' Connection failed: '. Mysqli_error ($con));} mysqli_select_db ($con, ' bdm256727651_db '); $username = "Select username from Forms where username = ' $_post[name] '"; $ result = Mysqli_query ($con, $username), $rows =mysqli_num_rows ($result), if ($rows) {echo "phone number registered"; exit;} Else{echo "mobile phone number available";} Mysqli_close ($con)?>
The above ajax+php to achieve no refresh verification of mobile phone number instance is a small part of the whole content to share to everyone, I hope to give you a reference, but also hope that we support PHP Chinese network.
