问题 What does $_GET return when the index is not set? (Couldn't find anything in php manual about $_GET.) I wrote this to check, if the $_GET['id'] isset - and if it is not, set $id to false: <?php $id = (isset($_GET['id'])) ? $_GET['id'] : false ?> 回答1: $_GET is just an ordinary array, so it behaves exactly the same as any other array. This means, it will return NULL to the variable and raise the "undefined index" notice when you call a non-existing index. The only thing you need to be aware of

问题 I am currently programming an API that gets passed data via get parameters so I was wondering if the total length of the URL or of the parameters value is limited in best practice or by the protocol. 回答1: Basically, 2K is the most you can rely on in a cross-browser fashion, but if you drop support for IE 8 and below, you can get to like 64K. Although I feel I need to question your need to know this, anything over say.. 100 characters would best be handled through a POST request instead of a

问题 I know the difference between POST and GET, however if I used POST instead of GET, anything not good besides not up to W3C standards? Anything inefficiency, insecurity or anything else? 回答1: See the answer from deceze: POST requests can't be bookmarked. In all the interviews I've done, all the teaching I've done, this is the best place to start. There's a lot more, but start with this. Ignore anything anyone says about security. A good hacker can change POST to GET easily. If you get this far
