08 Jul PHP GET Method
For sending information to the web server, use PHP GET method. It produces a long string, whenever you send information. This string can be seen in the address bar as well as in server logs. Here’s how it will be visible,
|
1 2 3 |
name1=value1&name2=value2 |
Let’s learn about some interesting points about the GET method,
- Never use GET, if you want to send passwords.
- Information sent via the GET method isn’t hidden and can be seen in the URL.
- There is a limitation of 1024 characters while sending information through GET.
- PHP superglobal variable $_GET is used to collect form data with GET.
- You can never send images, or documents, to the server, via GET.
Example
Here, we have two files. The first one is HTML form,
|
1 2 3 4 5 6 7 8 9 10 11 12 |
<html> <body> <form action="success.php" method="get"> Name: <input type="text" name="name"><br> Age: <input type="number" name="age"><br> <input type="submit"> </form> </body> </html> |
Here’s the output,
The second file is success.php which will open if the form submission is successful. We’re using superglobal variable $_GET to collect form data with GET.
|
1 2 3 4 5 6 7 8 9 10 |
<html> <body> Hi, User: <?php echo $_GET["name"]; ?><br> Your age: <?php echo $_GET["age"]; ?> </body> </html> |
Here, you can see the output. The URL shows the name and age information since we used the GET method. There’s a limitation of 1024 characters while sending information through GET. And since you can see the information in the URL, it is considered insecure. So, never use GET to send passwords.
