PHP base64 convert to jpg file is large - php

I open one file with 70kb :
$img = 'data:image/jpg;base64,'.base64_encode(file_get_contents($img));
If I save this code via below code, image saved with 1.5mb size!
$file = fopen('new.jpg', "wb");
$data = explode(',', $img);
fwrite($file, base64_decode($data[1]));
fclose($file);
How I can fix it?

Restore content file_get_content() function

I gave an image as a parameter to the file_get_content() function and received it as the output of a string. Now I want to do the opposite of this operation. What should I do?

You can write it back to an image file using file_put_contents
Example:
$pathToImage = '/images/test.png';
$newFile = '/images/test-new.png';
// Get the contents of the image file
$imgString = file_get_contents($pathToImage);
// Write it back to an image
file_put_contents($newFile, $imgString);
If you then look into your folder "images/", there should be a new file called "test-new.png"

Deal with image using base64
with file_put_contents
Online base64 image converte as string encode image
<?php
// Image as base64 truncated
$data = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAY8AAAFwCAYA...';
list($type, $data) = explode(';', $data);
list(, $data) = explode(',', $data);
$data = base64_decode($data);
$image = 'image.png';
file_put_contents($image, $data);
echo "<img src='$file' alt='image' />";

I wanted To convert Into Image and Upload To the Server
The Upload Folder Like
www.abc.com/uploads
And My File is
Www.abc.com/webservices/index.php (In this file I will write the code)
Thanks In advance

One way of doing it,
function writePng($data, $filename){
$bin = substr($data, strlen('data:image/png;base64,'));
$bin=base64_decode($bin);
$fp = fopen($filename,'w+');
fwrite($fp, $bin);
fclose($fp);
}
writePng($data, '1.png');

Generate PDF from base64 String PHP

I'm trying to create a .pdf file with a base64 string from an image, and I can create it correctly, but when I try to open the file, the program sends a message that tells the file is corrupt or something like that..
I got this code:
define('UPLOAD_DIR', '../image/');
$img = $_POST['image'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$uniqueNumber = uniqid();
$namefile = $uniqueNumber.'.png';
$file = UPLOAD_DIR . $namefile;
$success = file_put_contents($file, $data);
$namefile = $uniqueNumber.'.pdf';
$file = UPLOAD_DIR . $namefile;
$success = file_put_contents($file, $data);
I can open the .png file correctly so, i think it's not problem from the base64 decoded string. Thank you all!
EDIT:
I'm trying this code and getting the same issue.
$data = base64_decode ($img);
//Write data back to pdf file
$pdf = fopen ('test.pdf','w');
fwrite ($pdf,$data);
//close output file
fclose ($pdf);
echo 'Done';
Is that becouse i'm saving an image with .pdf ? I think no, because if i'm doing fopen with .pdf should be with that format.
EDIT 2:
FOUND A SOLUTION.
http://www.fpdf.org/en/script/script45.php
I followed these steps and i can get that, thank you all!

Check out DOMPDF: https://github.com/dompdf/dompdf
You can definitely use DOMPDF to create a PDF with an image tag whose source is that Base64 string. and render that to PDF.
<?php
require_once("dompdf_config.inc.php");
$img = $_POST['image'];
$html =
'<html><body>'.
'<img src="'.$img.
'"></body></html>';
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");
?>

unlink base64 encoded image not working

hi guys ive created a base64 encoded image captured with web cam now i convert the .png to .jpg all works fine but now i get two images on server both .png and .jpg how do i go about deleting the .png or is their a way to convert to jpg without saving .png image to disk thanx here my code
$rawData = $_POST['imgBase64'];
$filteredData = explode(',', $rawData);
$unencoded = base64_decode($filteredData[1]);
$randomName = rand(1000, 99999999999);
//Create the image
$fp = fopen('user/'.$randomName.'.png', 'w');
fwrite($fp, $unencoded);
//convert image from png to jpg
$image = imagecreatefrompng('user/'.$randomName.'.png');
imagejpeg($image, 'user/'.$randomName.'.jpg', 80);
unlink($fp);
ive tried it with
unlink($image);
unlink($_SERVER['DOCUMENT_ROOT'] . "/user/.$randomName.'.png'");
imagedestroy($fp);
imagedestroy($image);

Use the function unlink() but passing the file name to it instead of the file handler.
So from your example it would be:
EDIT: You might need to close the file first:
fclose( $fp );
unlink( 'user/'.$randomName.'.png' );

as far as i understand all you need is:
$data = base64_decode( $_POST['imgBase64']);
// image resource from your string
$image = imagecreatefromstring($data);
imagejpeg($image, 'user/'.$randomName.'.jpg', 80);

Create folder and save image into this folder that is send from android application

I have following PHP code to create a folder and save an image into this generated folder. What works is the generation of the folder, but the associated image will not be inserted into the folder, so the folder is always empty:
$uid = $_POST['uid'];
$image = $_POST["image"];
$suffix = $db->createRandomID(); //function creates random numbers and stores in $suffix
$url = "http://XXX.XXX.XXX.XX/uploads_offer/";
$image_name = "img_offer_".$suffix."".$uid."_".date("Y-m-d-H-m-s").".jpg";
$path = $url."".$image_name; // path of saved image
// base64 encoded utf-8 string
$binary2 = base64_decode($image);
// binary, utf-8 bytes
header("Content-Type: bitmap; charset=utf-8");
$filepath = $image_name;
if (file_exists("../uploads_offer/".$uid)){
//$file = fopen("../uploads_offer/".$uid . $image_name, "wb");
$file = fopen("../uploads_offer".$uid.$image_name, "wb");
fwrite($file, $binary2);
fclose($file);
}else{
$result8 = mkdir("../uploads_offer/".$uid, 0755);
$file = fopen("../uploads_offer".$uid.$image_name, "wb");
fwrite($file, $binary2);
fclose($file);
}

You are missing slashes (/) in your fopen() calls:
$file = fopen("../uploads_offer/".$uid."/".$image_name, "wb");
