Which one is faster? HTML alone or embeded in PHP?
<p>I have two pages:</p>

<p>index.php:</p>

<pre><code>&lt;?php
    $mtime = microtime();
    $mtime = explode(" ",$mtime);
    $mtime = $mtime[1] + $mtime[0];
    $starttime = $mtime;
    $text = '
    &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;
    &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
    &lt;head&gt;
    &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
    &lt;title&gt;Untitled Document&lt;/title&gt;
    &lt;/head&gt;
      &lt;body&gt;
        html content
      &lt;/body&gt;
    &lt;/html&gt;';
    echo $text;
    $mtime = microtime();
    $mtime = explode(" ",$mtime);
    $mtime = $mtime[1] + $mtime[0];
    $endtime = $mtime;
    $totaltime = ($endtime - $starttime);
    echo "This page was created in ".$totaltime." seconds";
?&gt;
</code></pre>

<p>and index2.php:</p>

<pre><code>&lt;?php
   $mtime = microtime();
   $mtime = explode(" ",$mtime);
   $mtime = $mtime[1] + $mtime[0];
   $starttime = $mtime;
?&gt;
&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;
&lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
&lt;head&gt;
&lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8" /&gt;
&lt;title&gt;Untitled Document&lt;/title&gt;
&lt;/head&gt;

&lt;body&gt;
&lt;?php echo 'html content'; ?&gt;
&lt;/body&gt;
&lt;/html&gt; 
&lt;?php
   $mtime = microtime();
   $mtime = explode(" ",$mtime);
   $mtime = $mtime[1] + $mtime[0];
   $endtime = $mtime;
   $totaltime = ($endtime - $starttime);
   echo "This page was created in ".$totaltime." seconds";
?&gt;
</code></pre>

<p>Test result for index.php:</p>

<pre><code>html content This page was created in 6.1988830566406E-5 seconds
</code></pre>

<p>and for index2.php:</p>

<pre><code>html contentThis page was created in 6.4849853515625E-5 seconds
</code></pre>

<p>Why HTML embed in PHP is faster than index2.php?</p>
