How to upload a image to directory - php

Question

I used the following code to upload an image to a folder. My folder name is ADS. Please help me to upload that image to my ADS directory.
root - localhost/dc/upload.php
(the code is in this location)
The image should be added to the folder in location localhost/dc/ADS
if (isset($_POST["submit"])) {
if (is_array($_FILES)) {
$file = $_FILES['myImage']['tmp_name'];
$source_properties = getimagesize($file);
$image_type = $source_properties[2];
if ($image_type == IMAGETYPE_JPEG ) {
$image_resource_id = imagecreatefromjpeg($file);
echo $target_layer = fn_resize($image_resource_id,$source_properties[0],$source_properties[1]);
echo imagejpeg($target_layer,$_FILES['myImage']['name']);
} elseif ($image_type == IMAGETYPE_GIF ) {
$image_resource_id = imagecreatefromgif($file);
echo$target_layer = fn_resize($image_resource_id,$source_properties[0],$source_properties[1]);
echo imagegif($target_layer,$_FILES['myImage']['name'] );
} elseif ($image_type == IMAGETYPE_PNG ) {
$image_resource_id = imagecreatefrompng($file);
echo$target_layer = fn_resize($image_resource_id,$source_properties[0],$source_properties[1]);
echo imagepng($target_layer,$_FILES['myImage']['name']);
}
}
}
function fn_resize($image_resource_id,$width,$height)
{
$target_width =540;
$target_height =400;
$target_layer=imagecreatetruecolor($target_width,$target_height);
imagecopyresampled($target_layer,$image_resource_id,0,0,0,0,$target_width,$target_height, $width,$height);
return $target_layer;
}
When I use this code the image is displayed as in the Image1. I need it be like in Image2 without any change to the image and also I need to have a text or image watermark on the image as in the Image3.

The PHP functions imagepng imagegif and imagejpeg all have an argument to pass a file name to. I refactored your code to show this.
<?php
if (isset($_POST["submit"])) {
if (is_array($_FILES)) {
$file = $_FILES['myImage']['tmp_name'];
$source_properties = getimagesize($file);
$image_type = $source_properties[2];
if ($image_type == IMAGETYPE_JPEG) {
$image_resource_id = imagecreatefromjpeg($file);
echo $target_layer = fn_resize($image_resource_id, $source_properties[0], $source_properties[1]);
imagejpeg($target_layer, "localhost/dc/ADS/" . $_FILES['myImage']['name']);
}
elseif($image_type == IMAGETYPE_GIF) {
$image_resource_id = imagecreatefromgif($file);
echo$target_layer = fn_resize($image_resource_id, $source_properties[0], $source_properties[1]);
imagegif($target_layer, "localhost/dc/ADS/" . $_FILES['myImage']['name']);
}
elseif($image_type == IMAGETYPE_PNG) {
$image_resource_id = imagecreatefrompng($file);
echo$target_layer = fn_resize($image_resource_id, $source_properties[0], $source_properties[1]);
imagepng($target_layer, "localhost/dc/ADS/" . $_FILES['myImage']['name']);
}
}
}
function fn_resize($image_resource_id, $width, $height) {
$target_width = 540;
$target_height = 400;
$target_layer = imagecreatetruecolor($target_width, $target_height);
imagecopyresampled($target_layer, $image_resource_id, 0, 0, 0, 0, $target_width, $target_height, $width, $height);
return $target_layer;
}
