php查询并重复mysql_fetch_数组

在数组中缓存查询中的所有行。循环访问缓存数组10次并打印。

$a= array();
$query= mysql_query("SELECT fileName FROM images");
while($row = mysql_fetch_assoc($query))
 $a[]= $row;

for ($i = 1; $i <= 10; $i++) {
 foreach ($a as $row)
   echo "<img src='images/images/{$row['fileName']}'/>";
}

当然,您需要清除 $row['fileName']

使用 mysql_data_seek()

$rs = mysql_query("SELECT * FROM item_user");
for($i = 1; $i <= 10; $i++)
{
    echo "$i\n";
    while(false !== ($r = mysql_fetch_array($rs)))
    {
        echo "  $r[0]\n";
    }
    mysql_data_seek($rs, 0);
}

这里有一个比访问数据库10次更好的方法。

//declare an array
$imageArray = array();

// repeat query 10 times
for ($i = 1; $i <= 10; $i++) {
   $query = @mysql_query("SELECT fileName FROM images");
    while($row = mysql_fetch_assoc($query)){
        extract($row);
        $imageArray[] = $fileName; //sequentially add each row to the array
    }
}
//loop over the array
//At this stage you can use the array for whatever you like. Iterating over an array is easy.

foreach ($imageArray as $image){
   echo sprintf('<img src="images/images/%s" />',$image);
}
