Question

$link = http://site.com/view/page.php?id=50&reviews=show

How can we add &extra=video after id=50?

• id is always numeric.
• url can have many other variables after ?id=50
• &extra=video should be added before the first & and after the 50 (value of id)

It will be used this way:

echo '<a href="' . $link . '">Get video</a>';

Thanks.

Answer 1

Is ID always the first post parameter? If so, then you could jsut do some sort of string manipulation. Use strpos($link, "&") to find out the position where you want to insert. Then do a few substr() based on that position and then append them all together. Its kind of hacky I know, but it will definitely work.

$pos = strpos($link, "&");
$first  = substr($link, 0, $pos);
$last = substr($link, $pos);
$extra = "&extra=video";
$newLink = $first . $extra . $last;

See this link for some of the string manipulation functions that I mentioned above: https://www.php.net/strings
