Image upload to Hostinger directory

I'm trying to upload an image to a Hostinger directory, but I'm not able to do so.

Below is a PHP script.

Note: The Base64 image is coming from an Android app.

<?php

$ftp_server = "ftp.endereço.server";
$ftp_user = "*****";
$ftp_pass = "*****";
$imageCodificada = $_POST['imageCodificada'];


//DECODIFICAR IMAGEM
$imageDecodificada = base64_decode($imageCodificada);


// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Não foi possível estabelecer conexão com $ftp_server"); 

// try to login
if (@ftp_login($conn_id, $ftp_user, $ftp_pass)) {
    echo "Conectado! na $ftp_user@$ftp_server\n";
    file_put_contents(include($_SERVER['DOCUMENT_ROOT']."/public_html/imagens/fotos_func/TESTE.jpg"), imageDecodificada);



} else {
    echo "Não foi possível estabelecer conexão com $ftp_user\n";
}

// close the connection
ftp_close($conn_id);  
?>

My PHP script does not give error, however the file does not appear in the directory.

Someone could help me on how to do this.

Thank you.
