PHP通過scandir循環輸出不同的文件名

我正在嘗試生成一個SQL命令列表，我稍後會插入它。在這個時候，我似乎被困在唯一的部分是循環文件名。我需要我的scandir循環訪問nofilter目錄，並在每次給出新行或sql查詢時更改$ image。我有下面的代碼和輸出。基本上沒有SQL查詢應具有相同的$圖像被回顯到它PHP通過scandir循環輸出不同的文件名

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` (

輸出看起來像這樣

就是這一切，還是你有更多？ – JvdBerg

這是什麼迴路？ 'for（$ i = 1351314000; $ i <= 1351400400; $ i + = 14400）{' –

@AnthonyHatzopoulos這些是UNIX時間戳。 – Kermit

根據您的評論，爲什麼不這樣做呢？

<php 
$time = time();

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);

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

這看起來工作完美！非常感謝。 –

很好，如果你喜歡stackoverflow上的答案，它通常接受他們或upvote答案 –

更好地刪除'.'和'..'文件，您可以使用'$ files = array_diff（scandir（$ dir），array（ '）'，'。'））;' –

你混淆了你的括號：

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

}

我開始格式化你的代碼，一旦它被格式化，你可以看到你的一個循環沒有做任何事情。如果你對代碼進行格式化，那麼看到這些東西就更容易了。

你的外部循環使用$images變量，然後有一個內部循環（見上文），它除了定義$image變量之外什麼也不做，然後你得到意想不到的結果，因爲你在使用這個變量。

我有同樣的觀點。同意！ –
