How do I code an IF statment within a string?

I've tried every combination I could think of, but nothing is working. How do I integrate an IF statement within a string?

This is the line I need integrated;

if ($row['SL'] == 'Yes') {echo '<li class=\"sl\">Short Sale</li>' ;}

This is what I tried;

elseif ($row['X'] == 'sold') { echo "
    <li id=\"price\"> $ {$row['SP$']}</li>
 " .
    { if ($row['SL'] == 'Yes') {echo '<li class=\"sl\">Short Sale</li>' ;} }
 . "
    <li>Days on Market: {$row['DOM']}</li>;
 }

What you are looking for is called Ternary Operator or Shorthand If/Else:

( condition ? true result : false result )

Example:

echo "<li id=\"price\">{$row['SP']}</li>" . ( $row['SL'] == 'Yes' ? '<li class="sl">Short Sale</li>' : '' ) . "<li>Days on Market: {$row['DOM']}</li>";

The above example is the same as:

echo "<li id=\"price\">{$row['SP']}</li>";
if ( $row['SL'] == 'Yes' ) echo '<li class="sl">Short Sale</li>';
else echo '';
echo "<li>Days on Market: {$row['DOM']}</li>";

You can "stack" ternary expressions so the complete example will look like:

echo 
    $row['X'] == 'sold' 
        ? "<li id=\"price\">{$row['SP']}</li>" .
          ( $row['SL'] == 'Yes' ? '<li class="sl">Short Sale</li>' : '' ) .
          "<li>Days on Market: {$row['DOM']}</li>" 
        : '';

important: you cannot build a ternary operator without else statement.

Use a ternary operator:

elseif ($row['X'] == 'sold') { echo "
    <li id=\"price\"> $ {$row['SP$']}</li>
 " . ($row['SL'] == 'Yes') ? '<li class="sl">Short Sale</li>' : ''
 . "
    <li>Days on Market: {$row['DOM']}</li>";
 }

You don't. You output the first half the string, then fully stop that statement, then evaluate your if, then output the rest of the string.

...
elseif ($row['X'] == 'sold') {
  echo "<li id=\"price\"> $ {$row['SP$']}</li>";
  if ($row['SL'] == 'Yes') {
    echo '<li class=\"sl\">Short Sale</li>'
  }
  echo "<li>Days on Market: {$row['DOM']}</li>";
 }

You can't "embed" an if statement in a string, firstly because that's not syntactically valid, but even if it was, if statements don't resolve to a value in PHP.

You just need to break it up:

elseif ($row['X'] == 'sold') { 
    echo "<li id=\"price\"> $ {$row['SP$']}</li>";

    if ($row['SL'] == 'Yes') {
        echo '<li class=\"sl\">Short Sale</li>';
    }

    echo "<li>Days on Market: {$row['DOM']}</li>;
 }
