php通过scandir循环以输出不同的文件名

Question

我试图生成稍后将插入的SQL命令列表。 这时我似乎唯一停留的部分是循环文件名。 我需要我的scandir遍历nofilter目录并在每次给出新行或sql查询时更改$ image。 我有下面的代码和输出。 基本上没有任何SQL查询应该具有相同的$ image被回显到其中

for ($i=1351314000; $i<=1351400400; $i+= 14400) {
    $images = scandir("/home/fb/public_html/post/uploads/nofilter/");
    foreach($images as $image) {

    }

//copy file over from no filter
$orig = "/home/fb/public_html/post/uploads/nofilter/".$image."";
$dest =   "/home/fb/public_html/post/uploads/".$image."";
//copy($orig, $dest);


//output
  echo "The number is " . $i . "<br />";
echo $image;
echo "<br>";
echo "<br>";
echo "<br>";

echo "

INSERT INTO `fb_fb`.`postcron_schedule` (
`id` ,
`status_message` ,
`link` ,
`photo_url` ,
`status_name` ,
`status_caption` ,
`status_description` ,
`uid` ,
`page_id` ,
`access_token` ,
`post_to` ,
`status_type` ,
`schedule_type` ,
`is_process` ,
`process_time` ,
`process_at` ,
`display_time` ,
`created_by`
)
VALUES (
NULL , '', '', '/home/fb/public_html/post/includes/../uploads/". $image ."', NULL , NULL , NULL , '0', '135031429962113', 'AAAGLZAMh7YSUBALRMCW60Rdol1kD80ZBNymqkgyQfBXDour2KsvVWKFcnZB9cU9OSLRMQjnEuKHZCTNoTZC4jf9GFtMU11BTD8JZAUFl0EVgZDZD', 'page', 'photo', 'schedule', '0', '". $i ."', NULL , '". $i ."', '100000103637895'
);
";

echo "<br>";
echo "<br>";

 }

输出看起来像这样

The number is 1351314000 8120925654_4041b7c50f_o.jpg

Answer 1

您已经把大括号弄混了：

// does nothing
for( $images as $image ) {

}

我开始格式化您的代码，格式化之后，您可以看到您的一个循环不执行任何操作。 如果您格式化代码，则更容易看到这些东西。

你的外循环使用$images变量，然后有一个内环（见上文），什么也不做，但定义$image变量，然后你，因为你然后使用这个变量中获得意想不到的效果。

Answer 2

根据您的评论，为什么不这样做呢？

<php
$time = time();
$images = scandir("/home/fb/public_html/post/uploads/nofilter/");
foreach($images as $image) {
    if ($image == '.' || $image == '..') {
        continue;
    }

    $time += 14400; //add 4 hours every interval

    //copy file over from no filter
    $orig = "/home/fb/public_html/post/uploads/nofilter/".$image."";
    $dest =   "/home/fb/public_html/post/uploads/".$image."";
    //copy($orig, $dest);


    //output
      echo "The number is " . $time . "<br />";
    echo $image;
    echo "<br>";
    echo "<br>";
    echo "<br>";

    echo "
