How to compress JSON with PHP?
You can compress the data with PHP’s output control. Just put this call at the start of your script before any output:
ob_start('ob_gzhandler');Now any output will be compressed with either gzip or deflate if accepted by the client.
In PHP 5.4 is now JSON_UNESCAPED_UNICODE so you can replace char:
\u00f3 -> Ĺ› = Ś
eq:
json_encode($data,JSON_UNESCAPED_UNICODE);
If apache is your choice (and it is, like mentioned in original question), you may add some rules into .htaccess:
<IfModule mod_deflate.c> AddOutputFilterByType DEFLATE text/html # Add any mime-type you think is appropriate here AddOutputFilterByType DEFLATE application/json</IfModule>
