锚标记用于滚动循环内的元素

Question

Faced a problem when working on .xml file parsing in PHP What can i put in the ancher tag in that case :

<?php
 foreach ($xml->issue as $issue ) {
  echo '<a name="$issue->id"></a>';
   //rest of code
}
 <a href="# "> //i dont know what to put after the "Diese".
?>

i want to scroll to an element inside the loop .

Answer 1

First, your <a href> tag is empty. And because of that, you won't see any links on your page:

<a href="example.com">TEXT HERE!!!</a>

Second, in PHP, it is not valid to introduce variables in single quoted strings, like you did. Iterpreter will not recognize them as variables and therefore will not convert them to their values. My solution (take a look at quoting style):

foreach ($xml->issue as $issue ) {
  echo '<a name="'.$issue->id.'">some link</a>';
}
