Encrypt large data using public key .ASC in php

I have a public key with extension .asc that I need to use to encrypt data and to send it in a plain text file. I am trying to accomplish this in a windows machine using php. Any ideas? Thanks,

first create new folder owner by www-data

mkdir /var/www/.gnupg
sudo chown -R www-data:www-data  /var/www/.gnupg

second try follow php code:

    putenv("GNUPGHOME=/var/www/.gnupg");
    $gpg = new gnupg();
    $publicData = file_get_contents('/var/www/html/web/resources/keys/public.asc');
    $privateData = file_get_contents('/var/www/html/web/resources/keys/SECRET.asc');
    $publicKey = $gpg->import($publicData);
    $gpg->addencryptkey($publicKey['fingerprint']);
    $encrypt = ($gpg->encrypt('Data to encrypt'));
    echo $encrypt;

Make sure you installed the gnupg extension for PHP.

$gpg = new gnupg();
$publicData = file_get_contents('public.asc');
$publicKey = $gpg->import($publicData);
$gpg->addencryptkey($publicKey['fingerprint']);
echo $gpg->encrypt('Data to encrypt');

Instead of encrypting a constant, replace by the file contents, and store the encrypted message wherever you want.
