how to decode utf-8 in php from utf-8 python encode?

Question

This the code in python

value.py

print('Print 😀 Smile 🥇 2nd Best Private'.encode('utf-8'))
# b'Print \xf0\x9f\x98\x80 Smile \xf0\x9f\xa5\x87 2nd Best Private'

value.php

#get value from value.py
$bio=rtrim(ltrim($temp[2]));
$bio = preg_replace("/U\+([0-9a-f]{4,5})/mi", '&#x${1}', $bio);
echo ($bio);

echo($bio);
//output = \xf0\x9f\x98\x80 Smile \xf0\x9f\xa5\x87 2nd Best Private'

Answer 1

Here's my naive approach (implemented in Windows).

Scripts :

type .\SO\71805811.py

 # -*- coding: utf-8 -*- print('Print Smile 2nd Best Private'.encode('utf-8'))

type .\SO\71805811.php

 <?php var_dump($argn); $pattern = '(\\\\x(?=[0-9A-Fa-f]{2}))'; // ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ positive lookahead assertion $replacement = '='; $encoded = preg_replace($pattern, $replacement, $argn); var_dump(quoted_printable_decode($encoded)); ?>

Output :

.\SO\71805811.py

 b'Print \xf0\x9f\x98\x80 Smile \xf0\x9f\xa5\x87 2nd Best Private'

.\SO\71805811.py | \php8\php.exe -F .\SO\71805811.php

 string(65) "b'Print \xf0\x9f\x98\x80 Smile \xf0\x9f\xa5\x87 2nd Best Private'" string(41) "b'Print Smile 2nd Best Private'"
