Php,file operation, how to implement a Readint and readUTF

Like my writeint and writeUTF.

    function write_int($value)    {        $data = pack('N', $value);        fwrite($this->file, $data);    }    function write_utf($value)    {        $this->write_int(strlen($value));        fwrite($this->file,$value);    }

How do Readint and readUTF come true?

I try to write, but the type is wrong

   function read_int()    {        $data = fread($this->file, 4);        return unpack('N', $data);    }    function read_utf($value)    {        $l = $this->read_int();#unpack返回一个array不是int        return fread($this->file,$l);#类型不对    }
