How to get some part from url in php-CodePudding

Here is my url

&tend_num=B&R/HO/51071/STP/NIT/ROURKELA/01

I would like to get tend_num. When printing the tend_num, it only prints B.

Here is my code

$tend_num = mysqli_real_escape_string($con, $_GET['tend_num']);

Here is query

$result = mysqli_query($con,"SELECT x.*, y.`fullname`, x.`id` as t_id FROM `tend_testing` x, `emp` y  WHERE x.`testfeng`=y.`id` AND x.`testfeng`='$_SESSION[ERP_SESS_ID]' AND x.tend_num ='$tend_num' AND x.`status`='1' ORDER BY x.`created_on` DESC limit $start,$limit");

As I can't get tend_num from url properly so it's difficult to get data from table.

CodePudding user response：

In order to know how to resolve this problem, you need to understand how GET parameters work in a url.

In the current request, you have actually 2 arguments:

tend_num=B
R/HO/51071/STP/NIT/ROURKELA/01 not defined

This is because the & character is used to divide the different arguments in the url.

The way to do this is to encode the & character using & which is the encoded version of &.

CodePudding user response：

If you can encode your url following code will work

$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['tend_num'];

if not possible then you may try this

  $url = 'http://localhost/xerp/basic/tender/tsupply.php?id=1&tend_num=B&R/HO/51071/STP/NIT/ROURKELA/01';
        preg_match('/tend_num=(.*)/', $url, $matches);
        print_r($matches);
