copied!<p>I am trying to make complex template library. The thing is that I am holding my own syntax and php inside the same file as mixed.</p> <ol> <li><p>First my syntax is parsed and reformatted. Output is usual html + php as string. I don't want to make cache file but use string containing the "middle" template instead.</p></li> <li><p>On this template (string containing php tags and html) the php operations should be executed.</p></li> </ol> <p>MyComplexTemplate(my syntax + php) =parse=> Template(HTML+PHP) =exec php=> Result(HTML)</p> <p>For 2. I am trying to use ob_start() with echo, but everything inside php tags gets vanished.</p> <p>For example:</p> <pre class="lang-php prettyprint-override"><code><?php $asd = "123"; ob_start(); echo "<div><?php echo $asd; ?></div>"; // Middle template $result = ob_get_contents(); ob_end_clean(); echo $result; ?> </code></pre> <p>The result should be "<div>123</div>". At the moment I get only div tags.</p> <p>This is just a simple example. My template will contain all kind of php operations inside php tags.</p> <p>Is this kind of operation possible somehow?</p> <h3>UPDATE</h3> <p>Template i.e.: (template.php) </p> <pre><code>.mySyntax (...) and so on <?php foreach($asd as $data): ?> <div><?php echo $data ?></div> <?php endforeach; ?> .mySyntax some text </code></pre> <p>Parsing template with MySyntaxParser and executing php after that, which is left untouched: </p> <pre><code><?php $t = new MySyntaxParser("template.php"); // My parser. Converts mySyntax to html. $asd = array("test1", "test2"); ob_start(); echo $t->parse(); // Should execute php code inside the string; $result = ob_get_contents(); ob_end_clean(); echo $result; ?> </code></pre> <h3>UPDATE</h3> <p>I want to achieve allmost exact thing like <a href="https://stackoverflow.com/a/1309805/878435">here</a> but require_once should somehow come from string:</p> <h1><strong>SOLUTION</strong></h1> <p>Actually the solution is in this topic <a href="https://stackoverflow.com/questions/1184628/php-difference-include-eval">PHP: Equivalent of include using eval</a> . eval must be used with pre and postpadded with php tags.</p> <p>Also you should check out <a href="http://www.intechgrity.com/understanding-php-eval-function-and-usage-do-more-than-just-evaluating/" rel="nofollow noreferrer"><strong>THIS</strong></a> blogpost.</p> <p>Like here: </p> <pre><code><?php $asd = "123"; ob_start(); eval ('?> <?php foreach(array("asd", "asx123") as $data): ?> <div><?php echo $data ?></div> <?php endforeach; ?> <?php;'); ob_flush(); ?> </code></pre>
