How to display them in such order using php

Answer 1

You can use CSS selectors:

tr:nth-child(even) {
    background: #F5F5F5;
}
tr:nth-child(odd) {
    background: #FFF;
}

Answer 2

You first need to fetch rows from database in your php script and then in php you can loop these rows and apply an odd or even class, I have made an example script using php array. In your case $items will contain rows fetched from DB.

$items = array("abc", "123", "def", "345", 'wer'); 
foreach($items as $key => $val) {
    if($key == 0 ) {
        $class = 'odd';
    }
    elseif($key%2 == 0) {
        $class = 'odd';     
    }
    else {
        $class = 'even';    
    }

    echo $class . " $val" ."<br/>";
}

Let me know if it help you.
