How can I build an array like this in PHP?





It should have unique keys each of whose corresponding values are arrays, and those arrays have multiple elements for each key.







Array (

    42 => Array ( 56, 86, 97 )

    51 => Array ( 64, 52 )

)

    $main = array();
    for ($i=0; $i<10; $i++) {
    // $i makes numeric keys
    $main[$i] = array();

    // Or instead, you could make a truly unique key name for each:
    $main[uniqid()] = array(...somevalues...);

    }


    Creates something like:

    Array
    (
    [4f105f361cdd1] => Array
    (
    )

    [4f105f361cf24] => Array
    (
    )

    [4f105f361cf33] => Array
    (
    )

    [4f105f361cf3c] => Array
    (
    )

    [4f105f361cf44] => Array
    (
    )

    )

    $arr = array(
    42 => array(56, 86, 97),
    51 => array(64, 52)
    );

    var_dump($arr);

    $array = array(42=>array(56,86,97),51=>array(64,52));

    $arraytest = array(

    51 => array(64, 52)
    );

    var_dump($arraytest);

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

By User
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

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.
