How can I put PHP into a php echo?

Question

I've a simple problem but I am a php beginner so I need your help.

I want to put a php echo into a php echo. I know that this is not possible but idk how to solve my problem.

There is a simple html list which shows the subjects only if the assigned value in the db is >0.

<li>
    <ul>
        <?php  if ($record['#1'] > "0") { echo "<li>#1</li>"; }?>
        <?php  if ($record['#2'] > "0") { echo "<li>#2</li>"; }?>
    </ul>
</li>

But I also want to show the whole list only if one of the values is >0 because otherwise the list will be empty. So I need something like this (I know it doesn't work this way):

<?php  
  if ($record['#1'] > "0" or $record['#2'] > "0") { 
     echo "
        <ul>
          <?php  if ($record['#1'] > "0") { echo "<li>#1</li>"; }?>
          <?php  if ($record['#2'] > "0") { echo "<li>#2</li>"; }?>
        </ul>
       </li>
     "; 
   }
?>

I'm assuming that this is part of a bigger string? Show the full code. — Qirel, Sep 14 '17 at 10:50
The whole code is really long because it has a lot of this list points. — elkloso, Sep 14 '17 at 10:58
Alright. The point is that you cannot do `echo "some string".if ($condition) { echo "add more strings"; }."foobar";`, as it seems as you are doing. Which is why a bit more code surrounding this block will allow us to see what you're actually trying to do, and in turn help you. — Qirel, Sep 14 '17 at 10:59

You can simplify this code as:

<ul>
<?php
  if($record['#1'] > 0)
    echo "<li>#1</li>";
  if($record['#2'] > 0)
    echo "<li>#2</li>";
?>
</ul>

You are alredy in the PHP-Tag. So don't open it again. Close and Open echo if you want. Link this:

<?php  
  if ($record['#1'] > 0 || $record['#2'] > 0) { 
     echo "
        <ul>
          "; if ($record['#1'] > 0) { echo "<li>#1</li>"; } echo"
          "; if ($record['#2'] > 0) { echo "<li>#2</li>"; } echo"
        </ul>
       </li>
     "; 
   }
?>

Or you are looking for a way how looks a bit better, like:

<?php  
  if ($record['#1'] > 0 || $record['#2'] > 0) { 
     $li1 = "";
     if ($record['#1'] > 0)
          $li1 = "<li>#1</li>";

     $li2 = "";
     if ($record['#2'] > 0) 
          $li2 = "<li>#2</li>";

     echo "
        <ul>
          $li1
          $li2
        </ul>
       </li>
     "; 
   }
?>

Add 2 Strings:

$foo = "blabla";

echo "I say:".$foo." and soooo"; // <- I say:blabla and soooo
echo "I say:$foo and soooo"; // <- I say:blabla and soooo

Please change the code given below

<?php  if ($record['#1'] > "0" or $record['#2'] > "0") {  ?>
  <ul>
    <?php  if ($record['#1'] > "0") { echo "<li>#1</li>"; }?>
    <?php  if ($record['#2'] > "0") { echo "<li>#2</li>"; }?>
  </ul>
</li>  <?php }?>

I think you forgot the syntax of the php tag. So please change like this and try

If you see the final `
";` it suggests everything is being echoed already, in which case it won't work with PHP-tags and `if`s inside. Not my downvote btw :-) (I nearly walked into the same trap)

@Qirel this is correct please see carefully. – Pranav MS Sep 14 '17 at 10:51

Like I said, it's not my downvote. But that `";` that's at the end of the string in the original question suggests that OP wants to put all this in the middle of a string - which won't work. – Qirel Sep 14 '17 at 10:52

@Qirel Sorry i got your point. Thanks. – Pranav MS Sep 14 '17 at 10:54

That's right. The first snippet is the current code. So you can see that I've already a php string which should be included into another. – elkloso Sep 14 '17 at 10:59

@elkloso see my code you will get your answer. – Pranav MS Sep 14 '17 at 11:02
