File Include

[Dysan]

Hi,

 

Is it good practice to include all of the following code inside a separate file, then link to it via each page? Does this increase security?

 

session_start();
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
  die(mysql_error());
}

mysql_select_db("db", $con);

It will save code space and mistakes since you don't have to repeat it on every page you use a DB.

Not really a security issue, that is what most programmers do. Including me. But in a slightly more complex manner.

When i make semi-large websites with multiple sql scripts, i always find it easier to make the dbconn.php page like you've done below and just include on all pages i need it on, it does make things a lot easier when working and can/will shorten your code slightly.

 

As for increasing security, im not sure that i makes any difference where you place that code, but then again i could be wrong
