Uploading a dynamic created image in php - php

Question

To Achieve : Resizing uploaded image and save to the filesystem
-- Suppose a 1600x1024 image is being uploaded, and the required dimension is 500x300. Thus, the solution I came to is resizing image while uploading. The code snippet is as follows :
<?php
if(isset($_FILES['image'])){
//print_r($_FILES); die;
$file = $_FILES['image'];
//print_r($file); die;
$filename = rand().time().'.'.end(explode('.', $file['name']));
//echo $filename; die;
if(move_uploaded_file('"image.php?filename='.$file['tmp_name'].'"', 'uploads/'.$filename)){
echo 'Uploaded '.$filename.' !';
}else{
echo 'Not Uploaded';
}
}
?>
<form method="POST" enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF'];?>">
<input type="file" name="image">
<input type="submit" value="Upload"/>
</form>
image.php
<?php
// Filename
$filename = $_GET['filename'];
// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = 500;
$new_height = 200;
// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
// Content type
header('Content-Type: image/jpeg');
// Output
imagejpeg($image_p, null, 100);
?>
Question is : How to use move_uploaded_files in the php created image with header Content-Type: image/jpeg
Thanks & Regards

Answer 1

You need to save the image using one of the following functions: imagejpeg, imagepng, imagegif, etc. If you set the second parameter to null, the raw image stream will be outputted directly. You need to specify image path there.
imagejpeg($image_p, 'new-image.jpg', 100);
If you want to detect image type automatically, you can use pathinfo to extract it.

Answer 2

Change from
if(move_uploaded_file('"image.php?filename='.$file['tmp_name'].'"', 'uploads/'.$filename)){
echo 'Uploaded '.$filename.' !';
}else{
echo 'Not Uploaded';
}
To
$resized_file = "image.php?filename=".$file['tmp_name'];
$resized_file = file_get_contents($resized_file);
if(file_put_contents('uploads/'.$filename, $resized_file))
{
echo 'Uploaded '.$filename.' !';
}
else
{
echo 'Not Uploaded';
}

Answer 3

You can use on same function or another file which you already use image.php.
I add some code on same function , is working for me please check for you.
if(isset($_FILES['image']))
{
//print_r($_FILES); die;
$file = $_FILES['image'];
//print_r($file); die;
$filename = rand().time().'.'.end(explode('.', $file['name']));
//echo $filename; die;
if(move_uploaded_file('"image.php?filename='.$file['tmp_name'].'"', 'uploads/'.$filename)){
echo 'Uploaded '.$filename.' !';
//once your file is uploaded you converting on same image
$filenameNew = $_GET['filename'];
// Get new dimensions
list($width, $height) = getimagesize($filename);
$new_width = 500;
$new_height = 200;
// Resample
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
// Content type
header('Content-Type: image/jpeg');
//store path
$imageName=rand().time()."test.jpg";
$imagestore="uploads/".$imageName;
// Output
imagejpeg($image_p,$imagestore,100);
}else{
echo 'Not Uploaded';
}
}
