DOM Manipulation in Wordpress (and elsewhere) using php

Image
By User



I'm quite new to the DOM manipulation world and I would like to get a head start in order to avoid common errors.





I am looking for the most efficient way to manipulate content generated by wordpress using php. At the moment I am using Simple HTML Dom which seems to work just fine. However I recently found DOMDocument and a few others and it would be very helpfull if someone cleared out which one is faster, better or at least will generate less errors in case of really bad markup.





Also on the side can someone explain what is this syntax (instead of $html this @$html)





Thank you very much

So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
