if then statement equivalent in php

Question

I am newish to php. But when i learned to program it was on a TI-83 Calculator. with the TI83 their was an if-then statements the could be used. I am writing some code to check if a directory is already created and if not create it. I need it to run the last half of the code either way. here is the code.

<?php
$dir = "/Applications/XAMPP/xamppfiles/htdocs/upload/$_POST[Itemid]/" ;
if (!file_exists($dir) and !is_dir($dir)) {
    $upload_dir = mkdir($dir, 0777);
}else{
foreach ($_FILES["file"]["error"] as $key => $error) {
    if ($error == UPLOAD_ERR_OK) {
    $filename = $_FILES["file"]["name"][$key];
    $filetemp = $_FILES["file"]["tmp_name"][$key];
$filetype = $_FILES["file"]["type"][$key];
$filesize = $_FILES["file"]["size"][$key];
   if (file_exists($dir . $filename))
  {
  echo $filename . " already exists. <br><br>";
  }
else
  {
  echo "Upload: " . $filename . "<br>";
  echo "Type: " . $filetype . "<br>";
  echo "Size: " . ($filesize / 1024) . " kB<br>";
  echo "Temporarily Stored in: " . $filetemp . "<br>";
  move_uploaded_file($filetemp,"$dir/$filename");
  echo "uploaded the file \"" . $filename. "\" to the \"/Applications/XAMPP/xamppfiles/htdocs/upload/\" Directory<br>" ;
  $con=mysqli_connect("localhost","root","","Inventory");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$sql="INSERT INTO ListPics (`1`, `Item_ItemID`)
VALUES
('$dir$filename', '$_POST[Itemid]')";


if (!mysqli_query($con,$sql))
 {
die('Error: ' . mysqli_error($con));
}
echo ($filename. " added to Database<br><br>");

mysqli_close($con);
  }
  }
  }
  }
?>

Yes I know this code is not secure. It will not ever see the interweb(Reverently bows head and says "Thank you Al Gore") It will sit snugly behind a VPN for personal use only. I just need to know how to execute the PHP equivalent of If Then Statements

Your `if`/`else` structures look fine; what exactly is the problem? — elixenide, Dec 16 '13 at 02:04
I need it to execute the else after the if even when the if is not true. — DcHerrera, Dec 16 '13 at 02:05
If you want to execute the else part even if is not true then don't use else. — Yogesh Suthar, Dec 16 '13 at 02:06
This is simple: `if(condition) { /* do something if condition is true */ } else { /* do something else if condition is false */ } /* do other stuff either way */` — elixenide, Dec 16 '13 at 02:07
HAHA I was way over thinking it. Copy and paste that as an answer so I can give you credit. — DcHerrera, Dec 16 '13 at 02:10
I think you should read this chapter from the manual http://www.php.net/manual/en/language.control-structures.php the manual is a must when you are learning php — Emilio Gort, Dec 16 '13 at 02:12

This is simple:

if(condition) {
    /* do something if condition is true */
}
else {
    /* do something else if condition is false */
}
/* do other stuff either way */

You only need the else if there is something that you want to do only if the condition is false. If you want to do it either way, then don't use else at all.
