HTML / PHP：我们如何将PHP变量插入到html的锚标签中？

Question

I have a .php page which has a lot of HTML parts in it. I am running a FOR loop and for each value in FOR loop, I want to pass a PHP variable in anchor tag which is inside the loop.

I have tried this:

for($i =0; $i<5 ; $i++)
{ 
<a href = "Test.html?ID= <?php $i ?> > Sample text </a>
}

But it isn't working.

Any number of ways. The point is to not mix the HTML with the PHP, keep them separately parse-able. Something like this:

for($i =0; $i<5 ; $i++)
{ 
    echo '<a href="Test.html?ID=' . $i . '"> Sample text </a>';
}

(In this example all of the code is PHP, and the HTML is a string that's echo-ed to the output.)

Or this:

for($i =0; $i<5 ; $i++)
{
?>
    <a href="Test.html?ID=<?php echo $i; ?>"> Sample text </a>
<?php
}

(In this example the PHP code is wrapped in <?php ?> tags and the HTML is kept outside those tags.)

As long as you keep PHP code in the <?php ?> tags and HTML out of those tags, the parsers will know the difference.
