입니다 그리고 이것은 내가 그것을 쓸 사용하고있는 코드입니다.

$fp = fopen('io2454929593', 'wb'); 
fwrite($fp, pack('C*', $bytes)); 
fclose($fp); 

나는 모두 1 바이트 길이의 파일을 얻을 수 있지만 길어야합니다. 내가 도대체 ​​뭘 잘못하고있는 겁니까?

Answer 1

이 작업을 시도 할 수 있습니다 :

$s = '0100100101001110'; // your binary string 

$chars = array_map('bindec', str_split($s, 8)); 
array_unshift($chars, 'C*'); 
echo call_user_func_array('pack', $chars); 

면책 조항 :이 코드는 단지 pack를 호출 할 방법을 보여; 큰 문자열에는 사용하지 말아야합니다.
