Encoding the compressed data into json string

Question

I am compressing the array as below,

<?php
    $input = array('name'=>'PHP');
    $compressed = gzcompress(serialize($input));

    echo '<pre>'; print_r($compressed);
?>

And it is printing the data as below

xœK´2´ª.¶2±RÊKÌMU².¶2¶R
ðP²®nJ»

Now, I would like to convert $compressed as a json string. Since the compressed data contains special characters, it throws error, So I tried JSON_UNESCAPED_UNICODE below is the code snippet.

<?php
    // $compressed value getting from above script
    echo json_encode($compressed,JSON_UNESCAPED_UNICODE);
?>

Still it is not working. Can anyone suggest how to encode a compressed data as a json string.

Try by using:

$data = base64_encode(gzcompress(serialize($input)));

To revert back:

$input = unserialize(gzuncompress(base64_decode($data)));

How can unserialize from client side? Say, Javascript or dart? – Hkm Sadek Nov 21 '19 at 12:36
