截斷中文字避免亂碼 Cut Chinese Characters

//截斷中文字並且避免結尾亂碼，但是就有可能會少一個字, 無解
function utf8_substr($StrInput,$strStart,$strLen){

自已寫的

function cut_string($str, $_length){
	$count = 0;
	$length = mb_strlen($str, 'utf-8');
	$new_str = '';

	for($i = 0; $i < $length; $i++){
		$char = mb_substr($str, $i, 1, 'utf-8');
		$b_length = strlen($char);
		if($b_length > 1){
			$count += 2;
		}else{
			$count ++;
		}

		if($count <= $_length){
			$new_str .= $char;
		}
	}

	return $new_str;
}

function cut_string($str, $_length){

$count = 0;

$length = mb_strlen($str, 'utf-8');

$new_str = '';

for($i = 0; $i < $length; $i++){

$char = mb_substr($str, $i, 1, 'utf-8');

$b_length = strlen($char);

if($b_length > 1){

$count += 2;

}else{

$count ++;

}

if($count <= $_length){

$new_str .= $char;

}

return $new_str;

}

Escape XML node value

if(!function_exists('escape_xml_value')){
    function escape_xml_value($str){
        $str = htmlspecialchars($str, ENT_XML1, 'UTF-8');

        return $str;

HTTP_RAW_POST_DATA

$GLOBALS[‘HTTP_RAW_POST_DATA’] works only on < PHP 5.5

        $data = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? json_decode($GLOBALS['HTTP_RAW_POST_DATA']) : null;
        if($data == false){
            $data = file_get_contents('php://input');
            if($data != false){
                $data = json_decode($data, true);
            }
        }

$data = isset($GLOBALS['HTTP_RAW_POST_DATA']) ? json_decode($GLOBALS['HTTP_RAW_POST_DATA']) : null;

if($data == false){

$data = file_get_contents('php://input');

if($data != false){
