添加php变量作为链接地址的一部分？

Question

I'm trying to add a variable as a part of a link, but I haven't could do it.

<?php
$fname=$data_array["firstname"];
echo '<a class="pin-button" href="https://myweb.com/description=$fname&amp;editable=false&amp;success_url=http%3A%2F%myweb.com%2Fsuccess"><img src="http://myweb.com/images/button.png" width="120"></a>';
?>

the link works perfect, but I need to add the variable after description=$fname

Thanks a lot!

1: $variables don't work inside single quotes, instead of

echo '<a href="$path">'`

try

echo "<a href='$path'>"

2: If you wish to use single quotes you can use concatenation instead:

echo '<a href="'.$path.'">'

3: In either case, you should be escaping your strings when printing them inside HTML:

echo "<a href='".htmlspecialchars($path, ENT_QUOTES)."'>"

This prevents characters (such as quotes and less-than signs) having unintended effects, and prevents exploits by maliciously crafted data.
