I Convert Base64 string in php to mp3 sound file but produced file wav Corrupted
Before convert tone sound is rustle
Such as voice files that convert :
http://vocaroo.com/i/s1Dlol5Wu3Zo
php code :
<?php
if(isset($_POST['audio'])){
$data = str_replace('data:audio/wav;base64,', '', $_POST['audio']);
$data = base64_decode($data);
$track_name = get_random_string(mt_rand(6,10)) . ".mp3";
$upl_dir = "../up/" . $track_name;
if( !file_put_contents($upl_dir, $data) ){
$response['status'] = 1;
$response['message'] = "File could not be uploaded. Try again >later.";
echo $data;
echo "E1";
}
echo $data;
}
I test sound before convert And was right.
Base64 Code :
https://ufile.io/174101
js code base64 creator:
function base641()
{
Fr.voice.export(function(url){
// console.log("Here is the base64 URL : " + url);
base = url;
ejem2 = 1;
// alert("Check the web console for the URL");
// $("<a href='"+ url +"' target='_blank'></a>")[0].click();
}, "base64");
};
try this :
file_put_contents('audio.mp3', base64_decode($data));

void _uploadFile(Event event) async {
print("called");
final files = uploadInput.files;
final file = files![0];
_fileNameController.text = file.name;
// Get the file contents as a List<int>
final reader = new FileReader();
reader.readAsArrayBuffer(file);
await reader.onLoad.first;
final contents = reader.result as List<int>;
// Encode the file contents as a base64 string
final encodedFile = base64Encode(contents);
var response = await http.post(Uri.parse("http://url/img_test/img.php"),
body: jsonEncode(<String, String>{
'file': encodedFile,
})
);
print(response.body);
if (response.statusCode == 200) {
// Handle the success case
print("ok");
} else {
// Handle the error case
print("try");
}
}
I all ready set as file in body but till it shows
Error shows in flutter
Warning: Undefined array key "file" in M:\WEB\htdocs\img_test\img.php on line 7
PHP API:
<?php
move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
?>
your request post not send file, this string value, you can try decode in your php file like this
$base64string = "data:image/jpeg;base64,".$POST['file'];
list($type, $base64string) = explode(';', $base64string);
list(,$extension) = explode('/',$type);
list(,$base64string) = explode(',', $base64string);
$fileName = uniqid()'.'.$extension;
$imageFile = base64_decode($base64string);
file_put_contents($path.$fileName, $imageFile);
I have a very simple PHP file that returns my image as BASE64 data
<?php
require_once 'database_connections.php';
$data = json_decode(file_get_contents("php://input"));
$id = mysqli_real_escape_string($con, $data->id);
$page = mysqli_real_escape_string($con, $data->page);
$path = "../../images/" . $id . '/' . $page . '.jpg';
$imagedata = file_get_contents($path);
$base64 = base64_encode($imagedata);
echo($base64);
?>
In my react app, I am fetching this data like below
export const getImage = async () => {
try {
const response = await axios.post(
url,
{
id: '11bb2c1b-c262-4171-b614-d8af46898efb',
page: '001',
}
);
return response.data;
} catch (error) {
// handle error
console.error(error.message);
}
};
my base64 response like below:
/9j/2wCEAAEBAQEBAQEBAQECAQEBAgICAQECAgICAgICAgIDAgMDAw...
and finally my FileSystem code is like below:
const image = await getImage();
const filename = FileSystem.documentDirectory + 'imagetest.jpg';
await FileSystem.writeAsStringAsync(filename, image, {
encoding: FileSystem.EncodingType.Base64,
});
I'm not getting any error but my file is not being saved as I try. I have been working on this for hours but didn't solve my issue.
any advice would be appreciated!
Edit: I can show the base64 image in an Image component.
you wont be able to see your saved image file in FileSystem.documentDirectory , you need to
FileSystem.readDirectoryAsync(FileSystem.documentDirectory).then(data => {
data.forEach(filename_ => {
console.log("=cached image==***===" + filename_)
})
to check if it is there. FileSystem.documentDirectory is only "pragmatically accessible"
I'm trying to send an image taken from the camera and converted to base 64 format to be converted into a JSON format. Everything is working fine except when I use the function of json.dump in python it adds \n to the image_64 base format, where in the server, it can't decode the picture properly- It's giving a blank image .
Python code to send the image :
import socket
import datetime
import json
import base64 , urllib
from cam import *
Signal = "200"
Date = datetime.datetime.now()
captureImage()
del(camera)
facechop('test_image.png')
image ='test_image.png'
image_64 = base64.encodestring(open(image,"rb").read())
print "----------------------------------------------"
try:
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(('X.X.X.X', 20001))
code = json.dumps({"number": Signal, "date" : "{:%m/%d/%Y}".format(Date), "image" : image_64}).encode('utf8')
client_socket.sendall(code)
receive = client_socket.recv(5012)
print receive
except Exception as e:
print("ERROR: "+str(e))
& the server code is :
function checkMessageRecieved(){
foreach ($this->changed as $key => $socket) {
$buffer = null;
while(socket_recv($socket, $buffer, 10240000, 0) >= 1) {
$n = trim($buffer);
$decodeJSON = json_decode($n, true);
$number = $decodeJSON['number'];
$date = $decodeJSON['date'];
$image = $decodeJSON['image'];
echo $number;
echo $date;
echo $image;
$image=str_replace("\n", "" , $image);
$img = str_replace('data:image/png;base64,', '', $image);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = __DIR__ . "/../photos/public/" . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
$this->sendMessage(trim("Successfully done...") . PHP_EOL);
unset($this->changed[$key]);
break;
}
}
}
I am using the below code from the library

I tried to convert the code given below to a gif image file but could not achieve it.
var encoder = new GIFEncoder();
encoder.setRepeat(0);
encoder.start();

var frames_array = st.split('|');
$.each(frames_array,function(index,value) {
encoder.addFrame(value);
});
encoder.finish();
var binary_gif = encoder.stream().getData();
var data_url = 'data:image/gif;base64,'+encode64(binary_gif);

I need to convert this encoded code to an gif image file. How can I achieve it further
try this , may this will help you
<?php
function base64url_decode($data) {
return base64_decode(str_pad(strtr($data, '-_', '+/'), strlen($data) % 4, '=', STR_PAD_RIGHT));
}
?>
Use this (PHP pseudo-code): http://php.net/manual/en/function.imagecreatefromstring.php
function imagegif_from_base64($base64)
{
return imagecreatefromstring(base64_decode(substr($base64, 22) /* remove the "data:image/gif;base64," string */));
}
related get image from base64 string
AS you are using jsgif library you You can do like this to decode image
$imgstr = 'data:image/gif;base64,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';
$new_data=explode(";",$imgstr);
$type=$new_data[0];
$imgdata=explode(",",$new_data[1]);
$imgstr = base64_decode($imgdata[1]);
// or choose any name instead sample.gif
file_put_contents("sample.gif", base64_decode($imgstr));
If you just wanna use PHP try this:
$str = 'data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAA...';
$data = str_replace('data:image/gif;base64,', '', $str);
$data = str_replace(' ', '+', $data);
$data = base64_decode($data); // base64 decoded image data
$source_img = imagecreatefromstring($data);
$file = uniqid() .'.gif';
$success = file_put_contents($file, $data);
This will save the .gif image in the same folder the php file is located.
I'm working on a project where i can select an image (simple file select) and send it via JSON to a PHP MySQL insert page.
Upload page looks like this:
if (input.files && input.files[0]) {
var FR = new FileReader();
FR.onload = function(e) {
$('#img').attr("src", e.target.result);
var Naam = $('input[type=file]').val();
$('#base').text(e.target.result);
var Foto = e.target.result;
var Barcode = $('#barcode').val();
obj['Barcode'] = Barcode;
obj['Naam'] = Naam;
obj['Foto'] = Foto;
//execute ajax send
$.ajax({
url : 'insert.php',
type : 'POST',
data : obj,
dataType : 'json',
success : function(msg) {
alert("msg");
}
});
//$.post("insert.php", obj, function (data) {}, "json");
//alert("msg");
};
FR.readAsDataURL(input.files[0]);
and my PHP page:
$Barcode = $_POST["Barcode"];
$Naam = $_POST["Naam"];
$Name = preg_replace('/^.+[\\\\\\/]/', '', $Naam);
$Foto = base64_decode($_POST["Foto"]);
$query = "INSERT INTO voorraad_foto (barbody, location, foto) VALUES ('$Barcode','$Name','{$Foto}')";
$results = mysqli_query($db,$query);
And my table field is a BLOB.
But when it execute this, everything works fine except that it doesn't insert it as a blob, but pure string
I've tried with removing the
preg_replace('#data:image/[^;]+;base64,#', '', $Foto)
but doesn't make any difference, same when trying to add headers, but nothing..
What am i doing wrong, or is there something obvious that i'm not getting?
Thx.
I solved it in some kind of way:
I wrote a function that gets the Base64 string, decodes it and writes it to a Temp file.
Then i read that file again and upload that to my databse.
When success, delete the file.
It may not be the most effecient way, but it works!
function WriteToImageAndGetData($base64_string, $File) {
//Write to file
$ifp = fopen($File, "wb");
$data = explode(',', $base64_string); //Split Base64 string
fwrite($ifp, base64_decode($data[1])); //Decode Base64 string
fclose($ifp);
//Read from file
$fp = fopen($File, 'r');
$data = fread($fp, filesize($File)); //Read file contents
$data = addslashes($data);
fclose($fp);
return $data;
}
