- imagecreatefrompng( ), imagecreatefromgif( ) and imagecreatefromjpeg( ):
Returns an image identifier representing the image obtained from the given filename

<?php
if (is_array($_FILES)) {
$file = $_FILES['image']['tmp_name'];
$sourceProperties = getimagesize($file);
$fileNewName = ($lastID + 1);
$folderPath = "../Images/Slider-Images/";
$ext = pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION);
$imageType = $sourceProperties[2];
$imgefolder = ($lastID + 1) . "." . $ext;
switch ($imageType) {
case IMAGETYPE_PNG:
$imageResourceId = imagecreatefrompng($file);
$targetLayer = imageResize($imageResourceId, $sourceProperties[0], $sourceProperties[1]);
imagepng ($targetLayer, $folderPath . $fileNewName. "." . $ext);
break;
case IMAGETYPE_GIF:
$imageResourceId = imagecreatefromgif($file);
$targetLayer = imageResize($imageResourceId, $sourceProperties[0], $sourceProperties[1]);
imagegif ($targetLayer, $folderPath . $fileNewName. "." . $ext);
break;
case IMAGETYPE_JPEG:
$imageResourceId = imagecreatefromjpeg($file);
$targetLayer = imageResize($imageResourceId, $sourceProperties[0], $sourceProperties[1]);
imagejpeg ($targetLayer, $folderPath . $fileNewName. "." . $ext);
break;

}
move_uploaded_file($imgefolder, $folderPath );
$_POST['image'] = $imgefolder;

?>We can use the function imageResize ( )
function imageResize($imageResourceId, $width, $height) {
