PHP将HTML编码和解码为二进制

Question

The database I am using is Postgresql and I downloading a webpage and storing in a BLOB. Like this:

<?php
$html = file_get_contents('http://www.example.com');
$encoded_html = base64_encode($html);

//Store encoded data in blob in database
?>

That part works fine. But when I try to decode it and display it, it comes out garabled.

<?php echo base64_decode($encoded_html); ?>

Do I have to add extra parameters when encoding and decoding the data?

Answer 1

If this works then the encode/decode functions work fine

<?php
$html = file_get_contents('http://www.example.com');
$md5 = md5($html);
$encoded_html = base64_encode($html);
$decoded_html = base64_decode($encoded_html);
echo (md5($decoded_html) == $md5) ? 'OK' : 'FAIL';
echo PHP_EOL;

If not then I'd suggest comparing the base64 data that you're putting into the database with what comes out.
