Pass parameter to another page in PHP

I am discussing How to pass parameters as type GET to another page. OR Pass parameters as GET without using a form.OR Pass parameters through URL.

When we are using a form of method GET the values of text boxes enclosed in the form are
send to the action page through the URL.We can also send values through URL without a form.


If we want to pass a variable to another page when click a link

<a href="target.php?n1=5">Click Here</a>

If we want to pass more than 1 values seperate them with ' & '.

<a href="target.php"?n1=5&n2=10&name=sbr>Click Here</a>

In target.php the values can be retrieved just like form values send as GET method.
That is

$n1=$_GET["n1"];
$n2=$_GET["n2"];
$name=$_GET["name"];

When we want to send values of php variables , these code may be helpful

1.Pass a single value to another page

t1.php

<?php
$n1=5;
?>


<a href="target.php?n1=<?php echo $n1 ;?>">Click Here</a>

target.php

<?php
echo $_GET["n1"];
?>

2.Pass more than one value to another page

t1.php

<?php

$n1=5;

$n2=7;

?>

<a href="target.php?n1=<?php echo $n1 ;?>&n2=<?php echo $n2;?>">Click Here</a>

target.php

<?php
echo $_GET["n1"];
echo $_GET["n2"];
?>

You can see these two examples of using this  method here :-

Hope that this post is helpful to you.
