动态地将值传递给php中的sms api？

Question

This is my sms url

"https://example.com/api/sendhttp.php?authkey=#############&mobiles=".$mobile."&message=".urlencode($rem)."&sender=abcdef&route=#"

Here is my Code

<?php
    session_start(); 

    $mobile=98994564564;
    $rem="Hi";

    $url=$_SESSION['smsurl'];
    echo $url;
?>

What I am trying to do here is I am calling this url through session variable. But when I am displaying the url, it is not getting value of $mobile and $rem.

It should display

"https://example.com/api/sendhttp.php?authkey=#############&mobiles=8994564564"&message=".urlencode("Hi")."&sender=abcdef&route=#"

Answer 1

The problem is, $_SESSION['smsurl'] does not contain the actual variables like $mobile or $rem, instead it contains the value of those variables. So you can't simply do $mobile=ABC; $rem="XYZ"; $url=$_SESSION['smsurl']; to change the query part of the URL.

The solution is,

• Parse the URL
• Change the query part of the URL
• Reconstruct the URL again

So your code should be like this,

<?php
    session_start(); 

    $mobile=98994564564;
    $rem="Hi";

    $urlArray = parse_url($_SESSION['smsurl']);
    parse_str($urlArray['query'], $qStringArray);
    $qStringArray['mobiles'] = $mobile;
    $qStringArray['message'] = urlencode($rem);
    $qString = http_build_query($qStringArray);

    $apiUrl = $urlArray['scheme'] . '://' . $urlArray['host'] . $urlArray['path'] . '?' . $qString;

    // Display the final URL
    echo $apiUrl;
?>
