Let's say I make the file below:

database.php

```
$db = new PDO("mysql:host=localhost; charset=utf8; dbname=myDb, username; password");

$sqlMyQuery1 = $db->prepare('SELECT * FROM tblTable1 WHERE Column1 = :Column1');
$sqlMyQuery1Param = array(':Column1' => $_POST[FormItem1]);

$sqlMyQuery2 = $db->prepare('SELECT * FROM tblTable2 WHERE Column1 = :Column1');
$sqlMyQuery2Param = array(':Column1' => $_POST[FormItem2]);

$sqlMyQuery3 = $db->prepare('SELECT * FROM tblTable3 WHERE Column1 = :Column1');
$sqlMyQuery3Param = array(':Column1' => $_POST[FormItem3]);

```

I then include this file to my other php files, so I can just do this on the fly:

```
$sqlMyQuery1 -> execute($sqlMyQuery1Param);

```

Given that in a real wesite, I'll have TONS of queries, will it affect the performance of my website, because I am "preparing" a bunch of queries everytime the page loads?
