PHP resize an image and upload to s3 - php

Question

I am using the following code which re-sizes an image to the height that I want.
function resizeToHeight($height) {
$ratio = $height / $this->getHeight();
$width = $this->getWidth() * $ratio;
$this->resize($width,$height);
}
However in my old code I was saving the image on the same server - I have since learned a little about s3 from Amazon and would like to upload the resized images to that.
Currently if I want to upload an image to S3 I do the following
function uploadmedia(){
include('s3upload/image_check.php');
$name = $_FILES['file']['name'];
$size = $_FILES['file']['size'];
$tmp = $_FILES['file']['tmp_name'];
$ext = getExtension($name);
if(in_array($ext,$valid_formats))
{
if($size < 1048576)
{
include('s3upload/s3_config.php');
//Rename image name.
$savename = base64_encode($name);
$actual_image_name = $savename.time().".".$ext;
if($s3->putObjectFile($tmp, $bucket , $actual_image_name, S3::ACL_PUBLIC_READ) )
{
$s3file='http://'.$bucket.'.s3.amazonaws.com/'.$actual_image_name;
}
else
$msg = "S3 Upload Fail.";
}
else
$msg = "Image size Max 1 MB";
}
else
{
$msg = "Invalid file, please upload image file.";
}
}
Now going back to the first code I would normally save the image via this method
$image = new SimpleImage();
$image->load($targetFile);
$image->resizeToHeight(80);
$image->save(rtrim($targetPath,'/') . '/' . md5($_FILES['Filedata']['name']) . '-x-h80.' . $ext);
function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null) {
if( $image_type == IMAGETYPE_JPEG ) {
imagejpeg($this->image,$filename,$compression);
} elseif( $image_type == IMAGETYPE_GIF ) {
imagegif($this->image,$filename);
} elseif( $image_type == IMAGETYPE_PNG ) {
imagepng($this->image,$filename);
}
if( $permissions != null) {
chmod($filename,$permissions);
}
}
function load($filename) {
$image_info = getimagesize($filename);
$this->image_type = $image_info[2];
if( $this->image_type == IMAGETYPE_JPEG ) {
$this->image = imagecreatefromjpeg($filename);
} elseif( $this->image_type == IMAGETYPE_GIF ) {
$this->image = imagecreatefromgif($filename);
} elseif( $this->image_type == IMAGETYPE_PNG ) {
$this->image = imagecreatefrompng($filename);
}
}
I was wondering if anyone knows of the way to instead of saving the image to the old file system, instead re-size the image to 80x80 and upload it to s3
Thank you.
Here is the full image resize script
class SimpleImage {
var $image;
var $image_type;
function load($filename) {
$image_info = getimagesize($filename);
$this->image_type = $image_info[2];
if( $this->image_type == IMAGETYPE_JPEG ) {
$this->image = imagecreatefromjpeg($filename);
} elseif( $this->image_type == IMAGETYPE_GIF ) {
$this->image = imagecreatefromgif($filename);
} elseif( $this->image_type == IMAGETYPE_PNG ) {
$this->image = imagecreatefrompng($filename);
}
}
function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null) {
if( $image_type == IMAGETYPE_JPEG ) {
imagejpeg($this->image,$filename,$compression);
} elseif( $image_type == IMAGETYPE_GIF ) {
imagegif($this->image,$filename);
} elseif( $image_type == IMAGETYPE_PNG ) {
imagepng($this->image,$filename);
}
if( $permissions != null) {
chmod($filename,$permissions);
}
}
function output($image_type=IMAGETYPE_JPEG) {
if( $image_type == IMAGETYPE_JPEG ) {
imagejpeg($this->image);
} elseif( $image_type == IMAGETYPE_GIF ) {
imagegif($this->image);
} elseif( $image_type == IMAGETYPE_PNG ) {
imagepng($this->image);
}
}
function getWidth() {
return imagesx($this->image);
}
function getHeight() {
return imagesy($this->image);
}
function resizeToHeight($height) {
$ratio = $height / $this->getHeight();
$width = $this->getWidth() * $ratio;
$this->resize($width,$height);
}
function resizeToWidth($width) {
$ratio = $width / $this->getWidth();
$height = $this->getheight() * $ratio;
$this->resize($width,$height);
}
function scale($scale) {
$width = $this->getWidth() * $scale/100;
$height = $this->getheight() * $scale/100;
$this->resize($width,$height);
}
function resize($width,$height) {
$new_image = imagecreatetruecolor($width, $height);
imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $this->getWidth(), $this->getHeight());
$this->image = $new_image;
}
}
// Define a destination
$targetFolder = '/uploads'; // Relative to the root
if (!empty($_FILES["Filedata"])) {
$name = $_FILES['Filedata']['name'];
$ext = end(explode(".", $name));
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') . '/' . md5($_FILES['Filedata']['name']) . '.' . $ext;
// Validate the file type
$fileTypes = array('jpg','jpeg','gif','png'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);
$link = array();
$link['large'] = "http://www.ipetfindr.com/petuploads/". md5($_FILES['Filedata']['name']) . '.' . $ext;
$link['small'] = "http://www.ipetfindr.com/petuploads/". md5($_FILES['Filedata']['name']) . '-x-h80.' . $ext;
move_uploaded_file($tempFile,$targetFile);
$image = new SimpleImage();
$image->load($targetFile);
$image->resizeToHeight(80);
$image->save(rtrim($targetPath,'/') . '/' . md5($_FILES['Filedata']['name']) . '-x-h80.' . $ext);
echo '1';
}
else
{print "did not work";}

You have the solution already with you.
$image = new SimpleImage();
$image->load($targetFile);
$image->resize(80,80);
$image->save($url);
That above part resizes the target file to 80X80
$s3->putObjectFile($targetFile, $bucket , $name_in_s3, S3::ACL_PUBLIC_READ);
The above part saves the targetfile to s3 bucket
unlink("/path/to/targetFile");
The above part to delete the targetFile on your machine, once you have uploaded to s3. If you forget this part, your system will be filled with resized images.
