我有这个代码：

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();
?>

问题在这里：

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

如果我偶尔使用 require 它不起作用。但是，如果需要一段时间，它会很有趣。如果我更改 require_once 并输入文本，它会很有趣。

问题是我在这样的对话框中看到了 require_once 的内容：http: //i50.tinypic.com/k1aslk.png

当它到达时 while 停止<div>。

new_aircraft.php

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

注意_once部分。包含该文件后，在脚本退出并启动新实例之前不会再次包含该文件。这是设计使然。如果您每次都想要该文件，请require()改用。

更改require_once为require或include。由于“一次”，您的脚本将仅在第一次迭代时包含该文件。

require和之间的区别在于，如果 PHP 无法找到该文件，它将破坏您的代码并报错include。require

include将触发警告，但允许您的脚本继续。
