下面php代码通过gzcompress和gzuncompress压缩和解压缩字符串，可以设定压缩级别

  1. $str = 'Hello I am a very very very very long string';
  2. $compressed = gzcompress($str, 9);//压缩级别为9
  3. $uncompressed = gzuncompress($compressed);
  5. echo $str, "\n";
  6. echo $uncompressed, "\n";
  7. echo base64_encode($compressed), "\n";
  8. echo bin2hex($compressed), "\n";
  9. echo urlencode($compressed), "\n";
复制代码

html5 - 像html或css等输出到前端的代码，应该优先保证其代码规范性还是优先确保其体积最小？ 若优先保证代码规范性，会导致产生许多冗余字符促使增加不必要的体积，使用户体验降低。若优先保证体积最小而去压缩代码，就会损失基本的代码规范性，导致可读性差。这两个应该怎样权衡呢？
