Initialize PHP echo without using ' ' or " "?

Question

I am currently working on a Webproject for my school which is build with HTML, PHP and SQL Databases for dynamic content. Until now everything works out pretty good but I have reached a point where I have to echo something out which contains many Characters like '' and "" which pretty much makes it impossible to use PHP echo with those starting tags ('' and ""). Is there any other way to start a PHP echo ?

if ($rows[$number]['kulturschule'] == 1) {

echo '<div class="tp-caption tp-resizeme hover-scale"
              data-x="center"
              data-y="center"
              data-voffset="[290, 290, 250, 210]"
              data-hoffset="0"
              data-frames='[{"delay":1000,"speed":2000,"frame":"0","from":"sX:0.9;sY:0.9;opacity:0;fb:20px;","to":"o:1;fb:0;","ease":"Power3.easeInOut"},{"delay":"wait","speed":500,"frame":"999","to":"sX:0.9;sY:0.9;opacity:0;fb:20px;","ease":"Power3.easeInOut"}]'
              style="z-index: 20; max-width: auto; max-height: auto; white-space: nowrap;"><a href="http://www.km-bw.de/Kulturschule"><img src="img/logo/kulturschule.jpg"></a>        ';

This is a perfect situation to use HEREDOC:

// put all the html in a variable:
$html = <<<EOT
     <div class="tp-caption tp-resizeme hover-scale"
          data-x="center"
          data-y="center"
          data-voffset="[290, 290, 250, 210]"
          data-hoffset="0"
          data-frames='[{"delay":1000,"speed":2000,"frame":"0","from":"sX:0.9;sY:0.9;opacity:0;fb:20px;","to":"o:1;fb:0;","ease":"Power3.easeInOut"},{"delay":"wait","speed":500,"frame":"999","to":"sX:0.9;sY:0.9;opacity:0;fb:20px;","ease":"Power3.easeInOut"}]'
          style="z-index: 20; max-width: auto; max-height: auto; white-space: nowrap;"><a href="http://www.km-bw.de/Kulturschule"><img src="img/logo/kulturschule.jpg"></a>
EOT;
// note, that EOT; has to be at the very start of the line.

// then:
echo $html;
