How to compress and output the JSON format data returned from the PHP program using gzip, jsongzip_PHP tutorial

Using gzip to compress and output the JSON format data returned in the PHP program, jsongzip

1. Comparison of HTTP output using compression and without compression

2. Enable gzip

Use apache mod_deflate module to enable gzip
How to activate:

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

Close method:

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

3. Set the type of gzip compressed output

The output type of json is application/json, so it can be set like this
Add

<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE application/json
</IfModule>

<&#63;php
$data = array(
  array('name'=>'one','value'=>1),
  array('name'=>'two','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);
&#63;>

Output before setting gzip:

4. A single json is output using gzip compression

After setting AddOutputFilterByType DEFLATE application/json, all data output in json format will be output using gzip compression.
If you only want to use gzip compression for a certain json, but not others, you can use the ob_start(); method.

First there is no need to set AddOutputFilterByType, then add ob_start('ob_gzhandler');

<&#63;php
ob_start('ob_gzhandler');

$data = array(
  array('name'=>'one','value'=>1),
  array('name'=>'two','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);
&#63;>
