Here is my code.

 

 

<?php

// Create connection

$con=mysqli_connect("localhost","root","","core_cs");

 

// Check connection

if (mysqli_connect_errno($con))

  {

  echo "Failed to connect to MySQL: " . mysqli_connect_error();

  }

  else

  { 

 

$sql="INSERT INTO user (msisdn1, imsi1)

VALUES

('".$_POST[msisdn1]."','".$_POST[imsi1]."')";

 

if (!mysqli_query($con,$sql))

 {

 die('Error: ' . mysqli_error($con));

 }

echo json_encode($sql);

}

mysqli_close($con);

 

 

 

?>

Array indexes should be strings.
