使用php在表中的每个4个图像处放置一行

这是您想要做的。它支持任意数量的行，每次输出4个。例如，如果有15个项目，它在前三行输出4个，在最后一行输出3个。

echo"<table border=1>";
$images = array();
$names = array();
while ($row = mysql_fetch_array($content))
{
    $images[] = $row['image'];
    $names[] = $row['name'];
}
while(!empty($images))
{
    echo "<tr>";
    foreach($images as $count=>$image)
    {
        echo "<td><img src='".$image."' width='100'></td>";
        if($count==3)
        {
            $images = array_slice($images, 4);
            break;
        }
    }
    echo "</tr><tr>";
    foreach($names as $count=>$name)
    {
        echo"<td>" . $name . "</td>";
        if($count==3)
        {
            $names = array_slice($names, 4);
            break;
        }
    }
    echo "</tr>";
}
echo"</table>";

这里有一个做同样事情的较短版本：

echo"<table border=1>";
//get images and names in two arrays
$images = array();
$names = array();
while ($row = mysql_fetch_array($content))
{
    $images[] = "<img src='".$row['image']."' width='100'>";
    $names[] = $row['name'];
}

while(!empty($images))
{       
    //output images     
    foreach(array($images, $names) as $items)
    {
        echo "<tr>";
        foreach($items as $key=>$item)
        {
            echo "<td>$item</td>";              
            //output only four of them
            if($key==3)
            {
                break;
            }
        }
        echo "</tr>";
    }
    //remove the first four images from $images because they're already printed
    $images = array_slice($images, 4);
    $names = array_slice($names, 4);
}
echo"</table>";

这有点粗糙，但应该可以

// store the cells in arrays instead of echoing them
$images=$names=array();
while ($row = mysql_fetch_array($content)){
       $images[]="<td><img src='".$row['image']."' width='100'></td>"; 
       $names[]="<td>" . $row['name'] . "</td>";
}
// split them into 4 each. This will give $image_cells[0] as an array with the first 4 images
// and $image_cells[1] containing the latter 4
$image_cells=array_chunk($images, 4); 
// same with $names
$name_cells=array_chunk($names, 4);
// echo the table 
echo"<table border=1>";
// echo a table row, concat the cells stored as an array to a string using implode
echo '<tr>'. implode('', $image_cells[0]).'</tr>';
// and again but using $name_cells[0] which is the first 4 names
echo '<tr>'. implode('', $name_cells[0]).'</tr>';
// second set of images
echo '<tr>'. implode('', $image_cells[1]).'</tr>';
// second set of names
echo '<tr>'. implode('', $name_cells[1]).'</tr>';
echo"</table>";
