note 84109 added to function.eval

As critmas at hotmail dot com describes in an early posts, you can treat php tags as processing instructions if you need to evaluate some php in an xml/xhtml document, e.g. for templating. Note this is limited to simple php statement evaluation and would not work with content which uses braces '{', you'll need to use include() for that. An example of this follows: <?php // setup a test document with some xhtml $doc = new DOMDocument(); $doc->loadXML('<div><h1><?php echo $title; ?></h1><p><?php echo $msg; ?></p></div>'); // execute an xpath query to get all php scriplets $xpath = new DOMXPath($doc); $scripts = $xpath->query("descendant::processing-instruction(\"php\")"); // define our placeholder variables $title = "foobar"; $msg = "a foo walks into a bar ..."; // fill in the template foreach($scripts as $script){ ob_start(); eval($script->data); $result = ob_get_contents();; ob_end_clean(); $script->parentNode->replaceChild($doc->createTextNode($result), $script); } echo $doc->saveXML(); ?> The result is: <?xml version="1.0"?> <div><h1>foobar</h1><p>a foo walks into a bar ...</p></div> Regards, Kris ---- Server IP: 202.89.58.1 Probable Submitter: 203.97.101.252 ---- Manual Page -- http://www.php.net/manual/en/function.eval.php Edit -- https://master.php.net/note/edit/84109 Del: integrated -- https://master.php.net/note/delete/84109/integrated Del: useless -- https://master.php.net/note/delete/84109/useless Del: bad code -- https://master.php.net/note/delete/84109/bad+code Del: spam -- https://master.php.net/note/delete/84109/spam Del: non-english -- https://master.php.net/note/delete/84109/non-english Del: in docs -- https://master.php.net/note/delete/84109/in+docs Del: other reasons-- https://master.php.net/note/delete/84109 Reject -- https://master.php.net/note/reject/84109 Search -- https://master.php.net/manage/user-notes.php
