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.

  1. No. You can however use the ternary operator.

    $a = 0;
    echo 'Foo ' . ($a == 0 ? 'zero' : 'non-zero') . ' Bar';


    Note the (), you need them.

  2. Use the PHP ternary operator, you can read more about it here.

    echo " <div id='tabs-".$match."'>
    <textarea id='".$match."' name='".$match."'>".
    ($COLUMN_NAME==$match ? $FIELD_WITH_COLUMN_NAME : "").
    "</textarea>
    <script type='text/javascript'>
    CKEDITOR.replace( '".$match."' );
    </script>
    </div>";

  3. This will work

    $val = "";
    if ($COLUMN_NAME === $match)
    {
    $val = $FIELD_WITH_COLUMN_NAME;
    }
    echo " <div id='tabs-".$match."'>

    <textarea id='".$match."' name='".$match."'>". $val ."</textarea>

    <script type='text/javascript'>
    CKEDITOR.replace( '".$match."' );
    </script>

    </div>";

  4. You can't nest an if inside an echo. You need either to split the echo into separate statements:

    echo " <div id='tabs-".$match."'>

    <textarea id='".$match."' name='".$match."'>";

    if ($COLUMN_NAME === $match)
    {
    echo $FIELD_WITH_COLUMN_NAME;
    }

    echo "</textarea>

    <script type='text/javascript'>
    CKEDITOR.replace( '".$match."' );
    </script>

    </div>";


    or to use the ternary operator:

    echo " <div id='tabs-".$match."'>

    <textarea id='".$match."' name='".$match."'>".

    (($COLUMN_NAME === $match) ? $FIELD_WITH_COLUMN_NAME : "")

    ."</textarea>

    <script type='text/javascript'>
    CKEDITOR.replace( '".$match."' );
    </script>

    </div>";

  5. use ... . ($COLUMN_NAME === $match) ? $FIELD-WITH_COLUMN_NAME : '' . ...

    dismiss the if in front of it

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()...
