How to resize an image file on php? - php

Question

I have an image file which is stored onto database as a blob (shown in the code). Once resized to 80*80(thumbnail) I need to store it onto some other database. I have resized and saved it as a file but I couldn't store the resized image onto database. How can I achieve this?
//resize image and save
include('MyImage.php');
$image = new MyImage();
$image->load($tmpName);
$image->resize(80,80);
$image->save('thumbnail.jpg');
//storing original image onto database
if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0)
{
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
$fp = fopen($tmpName, 'r');
$content = fread($fp, filesize($tmpName));
$content = addslashes($content);
fclose($fp);
if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
}
$query = "INSERT INTO image_tbl (name, size, type, content )".
"VALUES ('$fileName', '$fileSize', '$fileType', '$content')";
mysql_query($query) or die('Error, query failed');
}

Answer 1

The direct question to your answer is
//This goes after the frist block, after "$image->save('thumbnail.jpg');"
$fileSize=filesize('thumbnail.jpg')
$fp = fopen('thumbnail.jpg', 'rb');
$content = fread($fp, $fileSize);
$content = addslashes($content);
fclose($fp);
$query = "INSERT INTO image_tbl (name, size, type, content )".
"VALUES ('thumbnail.jpg', '$fileSize', 'image/jpeg', '$content')";
mysql_query($query) or die('Error, query failed');
You might recognize some elements of that code :-)
But believe me, you do not want this:
Storing BLOBs in the DB, that the DB doesn't understand is a bad idea
using strings and addslashes to achieve it, is very close to the worst case possible: You read the image into a string consisting of ca 50% unprintables, backslash it, transport it to the DB, where it is unbackslashed and parsed. Use prepared statements with parameters (if you really want to save the image in the DB)

Answer 2

Try this:
$file = $path_you_saved_image."/".$your_image_name;
$handle = fopen( $file , "rb" );
$img = fread($handle , filesize($file) );
$img = base64_encode($img);
$query = "insert into images (image) values ('$img')";
mysql_query($query) or die(mysql_error());

Answer 3

you code suggests that you have saved the resized image. Now open this resized image 'thumbnail.jpg' and process it, encode it and save it.
