Glob文件并按filemtime排序，分为几个月 [英] Glob files and sort by filemtime and into months

问题描述

是的，我知道这是丑陋的代码:)而且它不起作用.

Yes, I know this is ugly code :) And it doesn't work.

我要遍历目录中的所有.php文件，然后按文件时间戳对其进行排序，然后我希望将文件名回显到每个月.但是，如何解决此循环，以便每个月的回显输出正确? $ path中的文件按日期排序，但是所有月份中所有文件的$ link_title都相同，因此我看不到$ paths是按月排列的.

I'm globbing all the .php files in a directory and then sorting them by file timestamp, and then I want to echo the file names into each month. But how do I fix this loop so the echoed output of each month is correct? The files by $path are sorted by date, but the $link_title is the same for all files in all months, so I don't see that the $paths are getting arranged by month.

foreach (glob("*.php") as $path) {

        $files[$path] = filemtime($path);

} arsort($files);

$currentdate = strtotime(date("Y-m-d H:i:s"));

$julybegin = strtotime("2018-07-01 00:00:00");
$julyend = strtotime("2018-07-31 23:23:59");

$junebegin = strtotime("2018-06-01 00:00:00");
$juneend = strtotime("2018-06-30 23:23:59");

$maybegin = strtotime("2018-05-01 00:00:00");
$mayend = strtotime("2018-05-31 23:23:59");

$aprilbegin = strtotime("2018-04-01 00:00:00");
$aprilend = strtotime("2018-04-30 23:23:59");

$timestamp = filemtime ($path);
$link_title = $path;

    foreach ($files as $path => $timestamp) {

if($timestamp > $julybegin && $timestamp < $julyend) {
echo '<li>';
echo $path . ' ' . $link_title;
echo '</li>';

} else {

if($timestamp > $junebegin && $timestamp < $juneend) {
echo '<li>';
echo $path . ' ' . $link_title;
echo '</li>';

} else {

if (($timestamp >= $maybegin) && ($timestamp <= $mayend)){

echo '<li>';
echo $path . ' ' . $link_title;
echo '</li>';

} else {

if (($timestamp >= $aprilbegin) && ($timestamp <= $aprilend)){

echo '<li>';
echo $path . ' ' . $link_title;
echo '</li>';

}
}
}
}
}

这有效并输出jQuery手风琴的正确标记:

This works and outputs the correct markup for a jQuery accordian:

foreach (glob("*.php") as $path) {

    $timestamp = filemtime($path);

    $files[date('F', $timestamp)][$path] = $timestamp;

}

arsort($files); 

        echo '<div class="accordion">';

        foreach ($files as $month => $paths) {

            krsort($paths);

        echo '<h6>' . $month . '</h6><div><ul>';

        foreach ($paths as $path => $timestamp) {

        echo '<li>' . $path . '</li>';
    }
        echo '</ul></div>';

    }
        echo '</div>';

推荐答案

由于您的最终目标是按月对文件名进行分组，因此需要一个循环以仅向您显示$files数组中与特定字符串匹配的条目月:

Since your end-goal is to group the filenames by month, you need a loop to show you only the entries from the $files array that match a particular month:

$months = array(
    '2018-07',
    '2018-06',
    '2018-05',
    '2018-04'
);

foreach ($months as $month) {
    // just some example markup
    echo '<p>' . $month . '</p>';

    echo '<ul>';
    foreach ($files as $path => $timestamp) {
        if (date('Y-m', $timestamp) == $month) {
            echo '<li>' . $path . '</li>';
        }
    }
    echo '</ul>';
}

如果您已经知道不打算将$files数组用于其他任何事情，那么另一种选择可能是在处理glob结果时简单地将文件分组:

If you already know that you're not going to use your $files array for anything else, another option might be to simply group the files while processing the glob results:

foreach (glob("*.php") as $path) {
    $timestamp = filemtime($path);

    $files[date('Y-m', $timestamp)][$path] = $timestamp;
}

由于它现在是一个嵌套数组，所以不能简单地arsort()整个过程.但是您可以将其延迟，直到您想要遍历文件列表以生成所需的HTML输出:

Since it's now a nested array, you can't simply arsort() the whole thing. But you can delay that until you want to loop over the file list to generate the desired HTML output:

// first sort the whole thing by keys (year + month), so that the months are sorted:
krsort($files);

foreach ($files as $month => $paths) {
    // now sort the paths by their timestamps
    arsort($paths);

    // and output whatever markup you want
    echo '<p>' . $month . '</p>';

    echo '<ul>';
    foreach ($paths as $path => $timestamp) {
        echo '<li>' . $path . '</li>';
    }
    echo '</ul>';
}

在更新问题后进行编辑

您似乎误解了在循环中定义变量的基本概念.

You seem to be misunderstanding a basic concept of defining variables in loops.

您的代码中有两个单独的循环:一个处理glob()的结果，另一个将处理的结果转换为jQuery手风琴的标记.

You have two separate loops in your code: one that processes the result of glob() and one that turns the result of that processing into markup for your jQuery accordion.

通过在 first 循环中定义$monthname，当处理glob()结果完成时，它将保持其最后一个值.

By defining $monthname in the first loop, it will maintain its last value when processing the glob() result is finished.

您想在 second 循环中使用 $monthname，但是您没有在此处设置它.因此，它总是是相同的值:处理glob()结果时的最后一个值.相反，您应该在要使用的位置定义$monthname.

You want to use $monthname in the second loop, but you're not setting it there. Therefore, it will always be the same value: the last value it was when processing the glob() result. Instead, you should define $monthname where you want to use it.

旁注:由于我不知道您要显示什么内容，因此我在答案中使用了date('Y-m')作为示例.如果您始终希望将日期显示为date('F')，则只需将其用作数组键即可.这样就无需跟踪单独的$monthname变量，您只需在第二个循环中输出$month值即可.但是，如果您的文件中有在同一个月但在不同年份中被修改过的文件，则可能不是您想要的 .

Sidenote: I used date('Y-m') in my answer as an example, since I didn't know what you were going to display. If you always want to display the date as date('F'), you can simply use that for the array key instead. Then there's no need to keep track of a separate $monthname variable and you can simply output the $month value in the second loop. However, this might not be what you want, if you have files in there that have been modified in the same month but in different years.

对于您看到的特定警告，它们是由您现在将每个文件两次存储到$files数组中的事实引起的:

As for the specific warnings you're seeing, they are caused by the fact that you're storing each file into the $files array twice now:

foreach (glob("*.php") as $path) {
    if($path == 'index.php') {
    continue;
    }  // removes all files names index.php

/**** HERE: ****/
    $files[$path] = filemtime($path);

    $timestamp = filemtime ($path);
    // needed to define $timestamp

/**** AND HERE: ****/
    $files[date('Y-m', $timestamp)][$path] = $timestamp;

    $monthname = (date('F', $timestamp));
    // display month full name instead of month numeral
}

这意味着$files数组看起来像这样:

This means that the $files array looks something like this:

Array
(
    [/var/www/file.php] => 1529239095
    [2018-06] => Array
        (
            [/var/www/file.php] => 1529239095
        )

)

因为您仍然有第一个赋值，所以现在您偶尔尝试对时间戳(整数)(而不是数组)进行排序(错误地复制/粘贴，应该是arsort()而不是krsort()). path => timestamp条目.您应该删除该第一个任务.

Because you still have that first assignment in there, you now occasionally try to sort (which you copy/pasted incorrectly, it should be an arsort() instead of krsort()) a timestamp (integer) instead of an array of path => timestamp entries. You should remove that first assignment.
