Don t worry  But you should still use the second solution  plus an extra check for none of those variables existing   because there are security issues with   REQUEST  since   GET and   POST aren t the only sources for that array    There was a post about the problems with   REQUEST yesterday  I believe  Let me go find it   EDIT  Oh well  not directly a post  but here it is anyway  http   kuza55 blogspot com 2006 03 request-variable-fixation html

I d suggest using   POST and   GET explicitly    Using   REQUEST should be unnecessary with proper site design anyway  and it comes with some downsides like leaving you open to easier CSRF XSS attacks and other silliness that comes from storing data in the URL   The speed difference should be minimal either way

There are certain security concerns involved as a hacker can set a cookie that will override a   POST or   GET value  If you handle sensitive data  I would not recommend using   REQUEST      Xandor  you can t be used   GET alternative of   POST on some case   When      when you want to upload a file  when you don t won t to show a data in url    GET also has limits on the amount of information to send  The limitation is about 2000 characters    Other thing s there are few case when you can t retrieve a data using   POST  When     when data is passed in URL     For Rest Service    GET  - Provides a read only access to a resource    PUT  - Used to create a new resource    there is nothing be wrong to use   REQUEST   But the way to do that is to check   SERVER  REQUEST METHOD   explicitly  not rely on   POST being empty for a GET

I only ever use  GET or  POST  I prefer to have control   What I don t like about either code fragment in the OP is that they discard the information on which HTTP method was used  And that information is important for input sanitization   For example  if a script accepts data from a form that s going to be entered into the DB then the form had better use POST  use GET only for idempotent actions   But if the script receives the input data via the GET method then it should  normally  be rejected  For me  such a situation might warrant writing a security violation to the error log since it s a sign somebody is trying something on   With either code fragment in the OP  this sanitization wouldn t be possible

GET retrieves variables from the querystring  or your URL  gt    POST retrieves variables from a POST method  such as  generally  forms    REQUEST is a merging of   GET and   POST where   POST overrides   GET  Good to use   REQUEST on self refrential forms for validations

I use this    request    count   REQUEST   gt  1    REQUEST   GET    the statement validates if   REQUEST has more than one parameter  the first parameter in   REQUEST will be the request uri which can be used when needed   some PHP packages wont return   GET so check if its more than 1 go for   GET  By default  it will be   POST

REQUEST  by default  contains the contents of   GET    POST and   COOKIE    But it s only a default  which depends on variables order   and not sure you want to work with cookies   If I had to choose  I would probably not use   REQUEST  and I would choose   GET or   POST -- depending on what my application should do  i e  one or the other  but not both    generally speaking     You should use   GET when someone is requesting data from your application  And you should use   POST when someone is pushing  inserting or updating   or deleting  data to your application    Either way  there will not be much of a difference about performances   the difference will be negligible  compared to what the rest of your script will do

if  isset   GET  s          temp     GET  s      else      temp     POST  s        Use that because it is safer and it won t make noticeable speed difference

User · Answer

I would use the second method as it is more explicit  Otherwise you don t know where the variables are coming from   Why do you need to check both GET and POST anyway  Surely using one or the other only makes more sense

It s ugly and I wouldn t recommended it as a final solution when pushing code live  but while building rest functions  it s sometimes handy to have a  catch-all  parameter grabber   public static function parseParams          params   array        switch   SERVER  REQUEST METHOD              case  PUT           case  DELETE               parse str file get contents  php   input     params                GLOBALS      SERVER  REQUEST METHOD         params              break          case  GET                params     GET              break          case  POST                params     POST              break          default               params     REQUEST              break            return  params      Someone creative could probably even add to it to handle command line parameters or whatever comes from your IDE   Once you decide what a given rest-function is doing  you can pick one appropriate for that given call to make sure you get what you need for the deploy version  This assumes  REQUEST METHOD  is set

GET vs  POST  1  Both GET and POST create an array  e g  array  key    value  key2    value2  key3    value3         This array holds key value pairs  where keys are the names of the form controls and values are the input data from the user   2  Both GET and POST are treated as   GET and   POST  These are superglobals  which means that they are always accessible  regardless of scope - and you can access them from any function  class or file without having to do anything special   3    GET is an array of variables passed to the current script via the URL parameters   4    POST is an array of variables passed to the current script via the HTTP POST method   When to use GET   Information sent from a form with the GET method is visible to everyone  all variable names and values are displayed in the URL   GET also has limits on the amount of information to send  The limitation is about 2000 characters  However  because the variables are displayed in the URL  it is possible to bookmark the page  This can be useful in some cases   GET may be used for sending non-sensitive data   Note  GET should NEVER be used for sending passwords or other sensitive information   When to use POST   Information sent from a form with the POST method is invisible to others  all names values are embedded within the body of the HTTP request  and has no limits on the amount of information to send   Moreover POST supports advanced functionality such as support for multi-part binary input while uploading files to server   However  because the variables are not displayed in the URL  it is not possible to bookmark the page

Use REQUEST   Nobody cares about the speed of such a simple operation  and it s much cleaner code

User · Answer

You are prematurely optimizing  Also  you should really put some thought into whether GET should be used for stuff you re POST-ing  for security reasons

User · Answer

I would use   POST  and   GET because differently from   REQUEST their content is not influenced by variables order  When to use   POST and   GET depends on what kind of operation is being executed  An operation that changes the data handled from the server should be done through a POST request  while the other operations should be done through a GET request  To make an example  an operation that deletes a user account should not be directly executed after the user click on a link  while viewing an image can be done through a link
