In PHP, it supports various asking methods depends on which the capabilities and functionalities to be applied on request information before sending it to the server, volition be varied. The listing of PHP supported request methods are,

• GET
• POST
• PUT
• Caput

Nosotros can know about which method is used on server page asking, by using $_SERVER variable's REQUEST_METHOD alphabetize, we have seen recently. In this article, nosotros are going to discuss these types of PHP request methods to know their usage, limitations and etc.

PHP Become Method

This is the default method used while sending data by submitting HTML form. If an HTML form contains either GET or nothing equally the value of its method aspect, then, the form fields values will exist loaded into $_GET super global, using which we can access form fields from a PHP script. So, on submitting with any value of HTML form'south method attribute except Mail service, this PHP asking method will be taken by default.

On using this method, all the parameters will be sent as query cord of the URL to access PHP page from the server. This query string will exist separated with? mark. And, it contains all form field's name, value pair separated by an ampersand(&).

Permit the states accept a simple instance PHP program saved as php_get_request.php. Information technology deals with PHP Go request method, for getting more clear knowledge about it.

<?php if(count($_GET)>0) { print "<PRE>"; print_r($_GET); print "</PRE>"; } ?> <course> First Proper noun: <input type="text" name="txt_first_name"></br> Last Name: <input type="text" proper noun="txt_last_name"></br> <input type="submit" proper noun="submit" value="Submit"> </class>        

Since class tag doesn't accept any specification for request method, the default method GET will be taken. The following screen shot shows the entries of form fields.

On submitting these inputs, the URL requesting server page will be as follows.

http://localhost/php_samples/php_request_methods/get_request.php?txt_first_name=Vincy&txt_last_name=PHPPOT&submit=Submit.        

If we send form data containing some special characters, then the URL will be encoded with the rules nosotros have seen with PHP URL encoding.

Since all parameters are shown transparently with the requesting URL, this is not a secure method to pass sensitive information similar countersign, payment information and etc. In such situation, PHP Mail service method is used.

Sending POST request for PHP file

This method is used to transport big sized information without any size limitation in GET method. In this method, the information to be sent for accessing PHP page from the server will be done through HTTP header in a secure manner without transparency.

PHP POST methods are also used to send selected files to be uploaded to the target location of the server.

For sending information in such mode via an HTML course submit, nosotros demand to specify grade method as POST. Afterward changing form method, it is required to use $_POST global within PHP portion of to a higher place example, to display the posted data to the browser.

At present, the in a higher place code can exist changed as,

<?php if($_SERVER["REQUEST_METHOD"] == "POST") { if(count($_POST)>0) { impress "<PRE>"; print_r($_POST); print "</PRE>"; } } ?> <form method="Post"> First Proper name: <input type="text" name="txt_first_name"></br> Last Name: <input blazon="text" name="txt_last_name"></br> <input type="submit" proper name="submit" value="Submit"> </form>        

While executing this programme, no query cord will be appended with page URL; Rather the arguments are sent through HTTP headers.

PHP PUT Request

We tin can non utilise this method while requesting server page via HTML form submit. Because the above two kinds of PHP asking methods are valid to use with course input. If we want to send PUT request, then we can obtain it by using coil script or control line execution.

This is the easiest way of putting required file to the target location of the server, compared with PHP Mail method. Only, for handling such requests in a secure manner to avoid bearding overwrite, we need to configure with apache conf file past using script directive.

Caput Method in PHP

The server generated response data with the header returned for this type of asking volition be same as that of GET request. But, the departure is, that the response of Head request won't contains any element body, rather contains data about the chemical element, instead. So, this type of request will be used for some verification purpose.
