file get contents php input or HTTP RAW POST DATA which one is better to get the body of JSON request

Question

file get contents  php   input   or  HTTP RAW POST DATA - which one is better to get the body of JSON request   And which request type  GET or POST  should I use to send JSON data when using client side XmlHTTPRequest   My question was inspired from this answer  How to post JSON to PHP with curl  Quote from that answer      From a protocol perspective file get contents  php   input   is actually more correct  since you re not really processing http multipart form data anyway

Your second question is easy  GET has a size limitation of 1-2 kilobytes on both the server and browser side  so any kind of larger amounts of data you d have to send through POST

Actually php   input allows you to read raw POST data   It is a less memory intensive alternative to  HTTP RAW POST DATA and does not need any special php ini directives   php   input is not available with enctype  multipart form-data    Reference  http   php net manual en wrappers php php

The usual rules should apply for how you send the request  If the request is to retrieve information  e g  a partial search  hint  result  or a new page to be displayed  etc     you can use GET  If the data being sent is part of a request to change something  update a database  delete a record  etc    then use POST   Server-side  there s no reason to use the raw input  unless you want to grab the entire post get data block in a single go  You can retrieve the specific information you want via the  GET  POST arrays as usual  AJAX libraries such as MooTools jQuery will handle the hard part of doing the actual AJAX calls and encoding form data into appropriate formats for you

For JSON data  it s much easier to POST it as  application json  content-type  If you use GET  you have to URL-encode the JSON in a parameter and it s kind of messy  Also  there is no size limit when you do POST  GET s size if very limited  4K at most

php   input is a read-only stream that allows you to read raw data   from the request body  In the case of POST requests  it is preferable   to use php   input instead of  HTTP RAW POST DATA as it does not   depend on special php ini directives  Moreover  for those cases   where  HTTP RAW POST DATA is not populated by default  it is a   potentially less memory intensive alternative to activating   always populate raw post data    Source  http   php net manual en wrappers php php
