Example:

<code>

{{QuoteBox|<nowiki>$first = "car";</nowiki><br />

  $first = "car";

<nowiki>$second = "nation";</nowiki><br />

  $second = "nation";

<nowiki>$product= $first . $second;</nowiki><br />

  $product= $first . $second;

<nowiki>// Equivalent to:</nowiki><br />

  // Equivalent to:

<nowiki>$product= "carnation"</nowiki>}}

  $product= "carnation"

PHP recognizes variable names within strings, which are enclosed in double quotes. Since all variables begin with a dollar sign, it is easy to embed one string inside another. This is the preferred way to create HTML output.

For example:

For example:

<code>

{{QuoteBox|<nowiki>$first = "John";</nowiki><br />

    $first = "John";

<nowiki>$middle = "Quincy"</nowiki><br />

    $middle = "Quincy"

<nowiki>$last = "Adams";</nowiki><br />

    $last = "Adams";

     <br />

      

<nowiki>// Show full name, in bold format</nowiki><br />

    // Show full name, in bold format

<nowiki>echo "<B>$first $middle $last</B>";</nowiki>}}

    echo <nowiki>"<B>$first $middle $last</B>";</nowiki>

This outputs <nowiki>"<B>John Quincy Adams</B>"</nowiki> to the HTML page.

This outputs <nowiki>"<B>John Quincy Adams</B>"</nowiki> to the HTML page.
