Method of compressing output of JSON format data returned in PHP program with gzip, jsongzip_php tutorial

The JSON-formatted data returned in the PHP program is compressed with gzip output method, Jsongzip

1. Comparison of HTTP output with compression and not using compression

2. Turn on gzip

Use Apache Mod_deflate module to open gzip
To open a method:

sudo a2enmod deflatesudo/etc/init.d/apache2 restart

Close method:

sudo a2dismod deflatesudo/etc/init.d/apache2 restart

3. Set the type of output that requires gzip compression

The output type of JSON is Application/json, so you can set this
Join in the httpd.conf

 
  
   
  Addoutputfilterbytype DEFLATE Application/json
 
  

<?php$data = Array (' name ' = ' = ' one  ', ' value ' =>1),  Array (' name ' = ' = ') ', ' value ' =>2),  Array (' name ' = ' three ', ' value ' =>3),  Array (' name ' = ' four ', ' value ' =>4),  Array (' name ' = > ' Five ', ' value ' =>5),  Array (' name ' = = ' six ', ' value ' =>6),  Array (' name ' = ' = ' seven ', ' value ' = >7),  Array (' name ' = ' eight ', ' value ' =>8),  Array (' name ' = ' = ' nine ', ' value ' =>9),  Array (' Name ' = ' ten ', ' Value ' =>10), header (' Content-type:application/json '); Echo Json_encode ($data);? >

To set the pre-gzip output:

After setting the GZIP output:

4. Single JSON compressed output using gzip

After you set Addoutputfilterbytype DEFLATE Application/json, all data output in JSON format will use gzip compression output.
If you only want to use gzip compression output for one JSON, you can use the Ob_start () method to implement the other.

First, you do not need to set Addoutputfilterbytype, and then add Ob_start (' Ob_gzhandler ') at the beginning of the code;

<?phpob_start (' Ob_gzhandler '); $data = Array (' name ' = ' = ' one  ', ' value ' =>1),  Array (' name ' = = ' Both ', ' value ' =>2),  Array (' name ' = ' = ' three ', ' value ' =>3),  Array (' name ' = ' four ', ' value ' =>4), Array (  ' name ' = ' = ' five ', ' value ' =>5), Array ('  name ' = ' = ' six ', ' value ' =>6),  Array (' name ' = = ') Seven ', ' value ' =>7),  Array (' name ' = ' = ' eight ', ' value ' =>8),  Array (' name ' = ' = ' nine ', ' Value ' =>9) ,  Array (' name ' = ' ten ', ' Value ' =>10), header (' Content-type:application/json '); Echo Json_encode ($data);? >
