将PHP数组显示为动画？

I have a php array which I displaying with a while loop and it gets the data from a sql database, at the moment everything in the array appears instantly, but would it be possible to get them to display with a half second delay? Would i have to use Javascript?

You can put a <div> around your array, like this:

<div id="myElementID" style="display:none;">
MY ARRAY
</div>

and it will not be visible. With Javascript you can make it visible after, for instance, a 1000 milliseconds, with:

function showElement(id)
// make hidden element visible
{
  document.getElementById(id).style.display = "";
}

window.setTimeout("showElement('myElementID')",1000);

No other libraries are needed for this.

If you need to do multiple rows you can wrap a <div> around each row, or use the <tr> tag if your're using tables, like this:

<div id="myRow1" style="display:none;">
ROW 1
</div>
<div id="myRow2" style="display:none;">
ROW 2
</div>
<div id="myRow3" style="display:none;">
ROW 2
</div>
.......
<div id="myRowN" style="display:none;">
ROW N
</div>

And in your script:

for (i = 1; i <= N; i++) { 
  window.setTimeout("showElement('myRow"+i+"')",500);
}

You would still need the showElement() function.

Yes you need javaScript. Just use jQuery. Use CSS to hide the content container before the page loads and show the content (fadeIn()) after the desired time interval using setTimeout().

Here's a fiddle : http://jsfiddle.net/tnzqv4fx/

If you want to do this in your PHP you can call a javascript function with a timeout. Make sure you included the jQuery libary first en defined the method to call. It will be something like the code below. You can change the $delay variable for more or less delay between the different elements.

<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
    function makeVisible(id, delay)
    {
        setTimeout(function(){

            $('#'+id).fadeIn();

        }, delay);
    }
</script>

<?php
    $delay  = 500;
    $array  = array(1,2,3,4,5);

    $counter = 0;
    foreach($array as $value)
    {
        $uniqueId = 'aClassName'.$counter;

        echo '<div style="display:none;" id="'.$uniqueId.'">'.$value.'</div>';
        echo '<script>makeVisible("'.$uniqueId.'", '.($counter++*$delay).')</script>';
    }
?>
