The GET method is used to send data from a web form to the server through the URL. It is one of the most commonly used HTTP request methods in PHP and web development.<\/p>\n\n\n\n
When a user submits a form using the GET method, the form data becomes visible in the browser\u2019s address bar as query parameters.<\/p>\n\n\n\n
By the end of this training, you will be able to:<\/p>\n\n\n\n
$_GET<\/code><\/li>\n\n\n\n- Pass data through URLs<\/li>\n\n\n\n
- Understand the advantages and limitations of GET requests<\/li>\n<\/ul>\n\n\n\n
What is the GET Method<\/h2>\n\n\n\n
The GET method sends form data through the URL.<\/p>\n\n\n\n
Example URL:<\/p>\n\n\n\n
example.com\/page.php?name=Ali&city=Lahore<\/code><\/pre>\n\n\n\nIn this example:<\/p>\n\n\n\n
\nname=Ali<\/code><\/li>\n\n\n\ncity=Lahore<\/code><\/li>\n<\/ul>\n\n\n\nThese are query parameters sent to the server.<\/p>\n\n\n\n
Syntax of GET Method<\/h2>\n\n\n\nHTML Form Example<\/h3>\n\n\n\n<form method=\"GET\" action=\"welcome.php\">
<input type=\"text\" name=\"username\">
<input type=\"submit\" value=\"Submit\">
<\/form><\/code><\/pre>\n\n\n\nAccessing GET Data in PHP<\/h2>\n\n\n\n<?php
$username = $_GET['username'];
echo \"Welcome \" . $username;
?><\/code><\/pre>\n\n\n\nHow GET Method Works<\/h2>\n\n\n\n\n- The user fills out the form<\/li>\n\n\n\n
- The browser sends data through the URL<\/li>\n\n\n\n
- PHP receives the data using the
$_GET<\/code> superglobal<\/li>\n\n\n\n- The server processes and displays the result<\/li>\n<\/ol>\n\n\n\n
Example of GET Method<\/h2>\n\n\n\nHTML Form<\/h3>\n\n\n\n<form method=\"GET\">
Name: <input type=\"text\" name=\"name\">
<input type=\"submit\">
<\/form><\/code><\/pre>\n\n\n\nPHP Code<\/h3>\n\n\n\n<?php
if(isset($_GET['name'])) {
$name = $_GET['name'];
echo \"Hello \" . $name;
}
?><\/code><\/pre>\n\n\n\nSending Multiple Values<\/h2>\n\n\n\n<form method=\"GET\">
First Name: <input type=\"text\" name=\"fname\">
Last Name: <input type=\"text\" name=\"lname\">
<input type=\"submit\">
<\/form><\/code><\/pre>\n\n\n\n<?php
$first = $_GET['fname'];
$last = $_GET['lname'];
echo $first . \" \" . $last;
?><\/code><\/pre>\n\n\n\nAdvantages of GET Method<\/h2>\n\n\n\nEasy to Use<\/h3>\n\n\n\n
GET requests are simple and beginner friendly.<\/p>\n\n\n\n
Bookmarking<\/h3>\n\n\n\n
URLs with GET parameters can be bookmarked and shared.<\/p>\n\n\n\n
Fast Data Transfer<\/h3>\n\n\n\n
Suitable for small amounts of data.<\/p>\n\n\n\n
Useful for Search Pages<\/h3>\n\n\n\n
Often used in search forms and filters.<\/p>\n\n\n\n
Limitations of GET Method<\/h2>\n\n\n\nData Visible in URL<\/h3>\n\n\n\n
Information can be seen in the browser address bar.<\/p>\n\n\n\n
Limited Data Length<\/h3>\n\n\n\n
URLs have character limits.<\/p>\n\n\n\n
Less Secure<\/h3>\n\n\n\n
Sensitive information should not be sent using GET.<\/p>\n\n\n\n
Difference Between GET and POST<\/h2>\n\n\n\nFeature<\/th> GET<\/th> POST<\/th><\/tr><\/thead> Data Location<\/td> URL<\/td> Request Body<\/td><\/tr> Visibility<\/td> Visible<\/td> Hidden<\/td><\/tr> Security<\/td> Less Secure<\/td> More Secure<\/td><\/tr> Data Size<\/td> Limited<\/td> Large Amount<\/td><\/tr> Bookmark Support<\/td> Yes<\/td> No<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nBest Practices<\/h2>\n\n\n\n\n- Use GET for search and filter forms<\/li>\n\n\n\n
- Avoid sending passwords using GET<\/li>\n\n\n\n
- Validate all user inputs<\/li>\n\n\n\n
- Use
isset()<\/code> before accessing GET variables<\/li>\n<\/ul>\n\n\n\nReal World Uses of GET Method<\/h2>\n\n\n\n\n- Search forms<\/li>\n\n\n\n
- Product filters<\/li>\n\n\n\n
