PHP禁用zlib.output_compression

Question

我的站点在ini文件中将zlib.output_compression设置为On，它将在发送到浏览器时压缩所有响应。

如何禁用压缩只对二进制文件，PDF文件和excel文件，以便它可以正确地输出到浏览器时，下载一个文件？

Answer 1

在服务器中使用.conf文件，将压缩限制为正确的MIME类型

例如在/etc/httpd/conf.d/enable_mod_deflate.conf中

# mod_deflate configuration
<IfModule mod_deflate.c>
  # Restrict compression to these MIME types
  AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE text/xml
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE application/xml+rss
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE image/png
  AddOutputFilterByType DEFLATE image/gif
  AddOutputFilterByType DEFLATE image/jpeg

  # Level of compression (Highest 9 - Lowest 1)
  DeflateCompressionLevel 9

  # Netscape 4.x has some problems.
  BrowserMatch ^Mozilla/4 gzip-only-text/html

  # Netscape 4.06-4.08 have some more problems
  BrowserMatch ^Mozilla/4\.0[678] no-gzip

  # MSIE masquerades as Netscape, but it is fine
  BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

  <IfModule mod_headers.c>
    # Make sure proxies don't deliver the wrong content
    Header append Vary User-Agent env=!dont-vary
  </IfModule>
</IfModule>

不要忘记重启你的服务器

sudo service httpd restart

Answer 2

zlib.output_compression = on/off

在PHP中

ini_set("zlib.output_compression", "On");
ini_set("zlib.output_compression", "Off");
