PHP 讓json\_encode不要把東西轉成\uXXXX

<?php

function json_encode_ex($value) {

    if (version_compare(PHP_VERSION, '5.4.0', '<')) {

        $str = json_encode($value);

        $str = preg_replace_callback("#\\\u([0-9a-f]{4})#i", "replace_unicode_escape_sequence", $str);

        $str = stripslashes($str);

        return $str;

    } else {

        return json_encode($value, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);

    }

}



function replace_unicode_escape_sequence($match) {

    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');

}



echo json_encode_ex("中文字!@#$%^&*()"); echo "\n"; echo json_encode("中文字!@#$%^&*()");
