imagecreatefrompng() from base64 code? - php

is there a way to create an image with imagecreatefrompng() with this base 64 PNG code in PHP?


This works for me
<?php
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'

. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
?>

Does imgjpeg function automatically take care of verification.

I am receiving multiple image files from android and I am using imgjpeg function. My question is do I have to verify that received file is an image file and is not corrupt or does this function take care of this verification (image + not corrupt) stuff.
Here is my code.
$data = file_get_contents("php://input");
$imageName = str_replace( array('[', ']', '"') ,"" ,$_SERVER['HTTP_IMAGE']);
if($imageName){
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/jpeg');
imagejpeg($im, $imageName, 100 );
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
}
else{
echo "Image name is not there";
}

Save byte to file with php

I have a c# program with some bitmap datatypes which i would like to upload to my web server with HTTP.
So i am thinking of converting the bitmap to the datatype bytes and then post it as text to the server, the sever would then save it as a image file.
How would i do this in PHP?
I am guessing something like this? but then how would i specify the save path location?
<?php
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'

. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
?>

$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'

file_put_contents('img.png', base64_decode($data));

How can I show an image using a byte array created using C# in php?

I have a byte array and I got this from a C# developer, now I have to show a image using
this byte array:
I have tried with this example which is working fine:
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
. 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
But when I replace the value of $data with this array it's not showing any image. Also the format of array is very different.
Byte array: it's very long so I omitted some numbers in between.

Convert binary byte array to image in PHP

I have a web service in Java which returns the requested file contents in byte[] (byte array) form. Sometimes these files are HTML files and sometimes they're images. There is no restriction of which file type it is. I'm looking for a way to convert this array to a valid image/string. My working for text files is below:
$bytes = getArray();
$string = implode(array_map("chr", $bytes));
echo $string;
This is the output of the echo $string;

But I have no idea how to do this for image files. I could somehow write this array to a file and load the image but my project doesn't allow me to do that. I have to do this on the fly.

If all you want to do is show the image to the user, you simply need to serve the right content header with the response:
if (substr($string, 0, 4) == "\x89PNG") header('Content-Type: image/png');
else if (substr($string, 0, 2) == "\xFF\xD8") header('Content-Type: image/jpeg');
else if (substr($string, 0, 4) == "GIF8") header('Content-Type: image/gif');
echo $string;
An image is really just a blob of data (like the 'string' you have) plus an indication that it's an image (in HTTP, that would be the MIME header). Since you already have the blob, all you need is the header to make the browser interpret it as an image.

Try
$body = file_get_contents('php://input');
and also refer PHP - get image from byte array

You mean like in the examples shown here: http://us.php.net/manual/en/function.imagecreatefromstring.php
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
. 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}

Using below code we can create image from byte array code.
$userId = $userid;
$encoded_image = $imgurl;
$upload_path = $_SERVER["DOCUMENT_ROOT"]."/projectName/uploads/";
$LoginUserDetails = $this->getUserDetails($userId);
if ($LoginUserDetails->profile_image != "") {
$dbimgname = $LoginUserDetails->profile_image;
unlink($upload_path .$dbimgname);
unlink($upload_path . 'thumb_img/' . $dbimgname);
}
$decoded_image = base64_decode($encoded_image);
$imgname = md5(uniqid()) . ".png";
file_put_contents($upload_path . $imgname, $decoded_image);
$thumbnail = $upload_path . "thumb_img/" . $imgname; // Set the thumbnail name
$actual = $upload_path . $imgname; // Set the actual image name
// Get new sizes
$upload_image = $upload_path.$imgname;
// print_r($actual); print_r($thumbnail); print_r($upload_image); die;
list($width, $height) = getimagesize($upload_image);
$newwidth = 196; // This can be a set value or a percentage of original size ($width)
$newheight = 196; // This can be a set value or a percentage of original size ($height)
// Load the images
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefrompng($upload_image);
//print_r($upload_image); print_r($source); die;
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); // Resize the $thumb image.
imagepng($thumb, $thumbnail, 100); // Save the new file to the location specified by $thumbnail
return $imgname;

Unable to rotate image with PHP's imagerotate

I continue to get this error after trying to retrieve an image from my DB and rotate it:
Warning: imagecreatefromstring() [function.imagecreatefromstring]: Data is not in a recognized format
Here is what I'm calling to convert the blob data back into an image for rotation:
$SQL="SELECT * FROM images WHERE id={$id}";
$rh = mysql_query($SQL);
$image=mysql_result($rh,0,"image");
$source_image=imagecreatefromstring($image);
$rotate_image = imagerotate($source_image, 90, 0);
Am I missing a step?

This is what I ended up doing for it to work:
$SQL="SELECT * FROM images WHERE id={$id}";
$rs = mysql_query($SQL);
//rotate image
$image=mysql_result($rs,0,"image");
$source_image=imagecreatefromstring($image);
$rotate_image = imagerotate($source_image, 270, 0);
ob_start();
imagejpeg($rotate_image, null, 100);
$image_bin = mysql_real_escape_string(ob_get_contents()); data.
ob_end_clean();

I recommend to store image data in base64. No problem with storing character and binary.
Then it's easy as that :
<?php
$data = 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABl'
. 'BMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDr'
. 'EX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r'
. '8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
$data = base64_decode($data);
$im = imagecreatefromstring($data);
if ($im !== false) {
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
}
else {
echo 'An error occurred.';
}
?>
