PHP Form Handling
Get request is the default form request. The data passed through get request is visible on the URL browser so it is not secured. It is an associative array of variables passed to the current script via the URL parameters (aka. query string). Note that the array is not only populated for GET requests, but rather for all requests with a query string. You can send limited amount of data through get request. The GET variables are passed through urldecode().In general, a URL with GET data will look like this
Post request is widely used to submit form that have large amount of data such as file upload, image upload, login form, registration form etc. The data passed through post request is not visible on the URL browser so it is secured. You can send large amount of data through post request. It is an associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.
Both GET and POST create an array (e.g. array( key1 => value1, 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
