Can I call die after echo with PHP?


I'm trying to add some error checking inside my PHP script. Is it valid to do this:




if (!mkdir($dir, 0)) {
$res->success = false;
$res->error = 'Failed to create directory';
echo json_encode($res);
die;
}



Is there a better way to exit the script after encountering an error like this?

  1. That looks fine to me.

    You can even echo data in the die like so:

    if (!mkdir($dir, 0)) {
    $res->success = false;
    $res->error = 'Failed to create directory';
    die(json_encode($res));
    }

  2. Throwing a exception. Put code into a try catch block, and throw exception when you need.

  3. PHP has functions for error triggering and handling.

    if (!mkdir($dir, 0)) {
    trigger_error('Failed to create directory', E_USER_ERROR)
    }


    When you do this the script will end. The message will be written to the configured error log and it will also be displayed when error_reporting is enabled.

Why is this Javascript much *slower* than its jQuery equivalent?

I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). 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

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.
