require_once一会儿[关闭]

I have this code:

while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
    if($i++%2==0){
       $color="#FFFFFF";
    }else{
       $color="#CCCCCC";
    }

    ?>

    <tr bgcolor='<?php echo $color; ?>' onmouseover="this.style.background='#ABFB04';" onmouseout="this.style.background='<?php echo $color; ?>';">
    <?php

echo "<td class=tablelist>";

echo $row["ICAO"] . '</td><td class=tablelist>';

echo $row["Name"] . '</td><td class=tablelist>';

echo $row["WeightEmpty"] . '</td><td class=tablelist>';

echo $row["WeightFull"] . '</td><td class=tablelist>';

echo $row["CargoFull"] . '</td><td class=tablelist>';

echo $row["Range"] . '</td><td class=tablelist>';

echo $row["Price"] . '</td><td class=tablelist>';

echo $row["FirstClassSeats"] . '</td><td class=tablelist>';

echo $row["BusinessClassSeats"] . '</td><td class=tablelist>';

echo $row["EconomyClassSeats"]. '</td><td class=tablelist>';

echo "<img class='editaircraft' src='./images/info.png'></td></tr>"; 

?>
<script>
    $(function() {
        $( "#editaircraftdialog" ).dialog({
            autoOpen: false,
            width: 425
        });

        $( ".editaircraft" ).click(function() {
            $( "#editaircraftdialog" ).dialog( "open" );
            return false;
        });
    }); 
</script>

<div id="editaircraftdialog" title="Edit Aircraft">
    <?php require_once('./new_aircraft.php'); ?> 
</div>

<?php
}

echo "</table>";
$pagination->render();
?>

The problem is here:

<div id="editaircraftdialog" title="Edit Aircraft">
        <?php require_once('./new_aircraft.php'); ?> 
    </div>

If I use the require once in a while it not works. But if the require is out a while it works fun. If i change the require_once and I put text, It works fun.

The problem is what I see the content of the require_once out a dialog like this: http://i50.tinypic.com/k1aslk.png

The while stops when it arrive to the <div>.

new_aircraft.php

<script>
    $(function() {
        $("#insertaircraft")
            .button()
            .click(function(event) {
        });
    });
</script>

Notice the _once part. Once you've included that file, it will not be included again until the script exits and a new instance is fired up. This is by design. if you want the file each time, then use require() instead.

change require_once to require or to include. Because of the 'once' your script will only include the file on the first iteration.

The difference between require and include is that require will break your code with an error if PHP cannot find the file.

include will trigger a warning but allow your script to continue.
