php urlcode 怎样实现加密解密

? PHP ?,??????????? URL ????????,????? urlencode() ? urldecode() ??????????

1. URL ??(?? urlencode() ??):

$url = "https://www.example.com?param1=value1¶m2=value2";
$encoded_url = urlencode($url);
echo "Encoded URL: " . $encoded_url; // ??:Encoded URL: https://www.example.com?param1=value1¶m2=value2

2. URL ??(?? urldecode() ??):

$decoded_url = urldecode($encoded_url);
echo "Decoded URL: " . $decoded_url; // ??:Decoded URL: https://www.example.com?param1=value1¶m2=value2

????????????????,???? PHP ?????? openssl?????? openssl_encrypt() ? openssl_decrypt() ????????????:

1. ??(?? openssl_encrypt() ??):

$data = "https://www.example.com?param1=value1¶m2=value2";
$encryption_method = "AES-256-CBC";
$key = "your-secret-key"; // ???????? 32 ???(256 ?)
$iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length($encryption_method));
$encrypted_data = https://www.yisu.com/ask/openssl_encrypt($data, $encryption_method, $key, 0, $iv);"Encrypted data: " . base64_encode($encrypted_data . '::' . $iv) . PHP_EOL; // ??:Encrypted data: base64????????::iv?

2. ??(?? openssl_decrypt() ??):

$encrypted_data = https://www.yisu.com/ask/base64_decode($encrypted_data .'::' . $iv); // ???????????? IV
$decrypted_data = https://www.yisu.com/ask/openssl_decrypt($encrypted_data, $encryption_method, $key, 0, $iv);"Decrypted data: " . $decrypted_data . PHP_EOL; // ??:Decrypted data: https://www.example.com?param1=value1¶m2=value2
