2. Data submitted by the GET method is appears into the browser location box.
3. There is limit to send only the limited data, you can send only 1024 characters by using the GET method.
4. Data send by the GET method is not secure because it appears on the browser location box,

Use of the GET and POST methods in PHP scripts.

Here are the example, how we can use the GET and POST methods into the HTML?

<form action="index.php" method="post">
	Your custom code here
</form>

<form action="index.php" method="get">
	Your custom code here
</form>

If we are using the POST method then values will be declared as

$values = $_POST[‘values’];

If we are using the GET method then values will be declared as

$values = $_GET[‘values’];

Example of the GET method:

<form action="index.php" method="get">
	User Name: <input type="text" name="uname" />
	User Age: <input type="text" name="uage" />
	<input type="submit" value="Submit" />
</form>

Now, when you enters the information whics is as,
“User Name: EWA, User Age: 25” and clicks on the Submit buttons, then the resulting URL would be

http://test.com/index.php?uname=EWA&uage=25

You display this data on the index.php as the example given below:

<?php
	echo $_GET['uname']; // Output would be EWA 
	echo "<br>";
	echo $_GET['uage']; // Output would be 25
?>

Example of the POST method:

<form action="index.php" method="post">
	User Name: <input type="text" name="uname" />
	User Age: <input type="text" name="uage" />
	<input type="submit" value="Submit" />
</form>

Now, when you enters the information whics is as,
“User Name: EWA, User Age: 25” and clicks on the Submit buttons, then the resulting URL would be

http://test.com/index.php

You display this data on the index.php as the example given below:

<?php
	echo $_POST['uname']; // Output would be EWA 
	echo "<br>";
	echo $_POST['uage']; // Output would be 25
?>
