this is an example of a mysql connection and php function combined.

I have thought of ways to create code but my code is very disorganized.  

What is a code example of combing the login, select, update using php.

I think what you want is an example of connecting to the db and doing the update. Is this what you want?

<?php
$con=mysqli_connect("example.com","peter","abc123","my_db");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$result = mysqli_query($con,"SELECT * FROM Persons");
$updatecmds = array();

while($row = mysqli_fetch_array($result))
  {
 $updatecmds[] = "UPDATE tbl SET column3='" .
     mysqli_real_escape_string($con, 'begin' . $row['column2']  . 'end') . "';";  
  }

mysqli_close($con);

foreach ($cmd in $updatecmds)
    mysqli_query($con, $cmd);
?>

The referred question is about prepending and appending - not about login and select?

If by "login" you mean PHP client authentication, this article shows the way.

Words like "login" and "select" have not got any single specific meaning in computer science.  They are terms of art, but the meanings range over a lot of intellectual territory.  So when you ask for an example of "login" it's like asking for an example of "England."  There are so many answers that it's not possible to predict which one(s) might be useful to you.

If you want to try to explain what you're looking for in a little more detail, we can probably help you find something that satisfies the need for an example.
