The following code just declares a string variable that contains a MySQL query    sql    INSERT INTO users  username  password  email      VALUES       POST  username           POST  password           POST  email           It does not execute the query  In order to do that you need to use some functions but let me explain something else first   NEVER TRUST USER INPUT  You should never append user input  such as form input from   GET or   POST  directly to your query  Someone can carefully manipulate the input in such a way so that it can cause great damage to your database  That s called SQL Injection  You can read more about it here  To protect your script from such an attack you must use Prepared Statements  More on prepared statements here  Include prepared statements to your code like this    sql    INSERT INTO users  username  password  email      VALUES             Notice how the   are used as placeholders for the values  Next you should prepare the statement using mysqli prepare    stmt   mysqli prepare  sql     Then start binding the input variables to the prepared statement    stmt- gt bind param  sss     POST  username      POST  email      POST  password       And finally execute the prepared statements   This is where the actual insertion takes place    stmt- gt execute      NOTE Although not part of the question  I strongly advice you to never store passwords in clear text  Instead you should use password hash to store a hash of the password
