我正在处理如下所示的php代码,其中我试图检索 mp4和xml文件的名称。
$src_dir = 'incoming_folder'; /* Place where mp4 file is present */
$mp4_files = preg_grep('~\.(mp4)$~', scandir($src_dir)); /* Line #Y */
print_r($mp4_files); /* Line #A */
$xml_files = preg_grep('~\.(xml)$~', scandir($src_dir)); /* Line #Z */
print_r($xml_files); /* Line #B */
Line#A打印以下内容:
Array ( [2] => 45017P.mp4 [3] => 45031P.mp4 [5] => hello.mp4
行#B打印以下内容:
Array ( [2] => 45017.xml [5] => 45031P.xml [7] => hello.xml )
我在下面的html中集成了 Line#Y 和 Line#Z 代码,以便从目录中检索文件名。
<table width="100%">
<tr>
<!-- This inline css will go inside addiional css -->
</tr>
<th style="width:8%;">House#</th>
<th style="width:8%;">Date</th>
<th style="width:8%;" >Time</th>
<th style="width:8%;">MP4</th>
<th style="width:8%;" >XML</th>
<?php foreach ($mp4_files as $file ) {
foreach ($xml_files as $file2 ) {
?>
<tr>
<td style="width:8%; text-align:center;"> <?php echo basename($file, ".mp4"); ?></td>
<td style="width:8%; text-align:center;"><?php echo date("F d Y",filemtime("incoming_folder/$file")); ?></td>
<td style="width:8%; text-align:center;"><?php echo date("H:i:s",filemtime("incoming_folder/$file")); ?></td>
<td style="width:8%; text-align:center;"> <?php echo basename($file); ?></td>
<td style="width:8%; text-align:center;"> <?php echo basename($file2); ?></td>
</tr>
<?php
}
}
?>
</table>
上面的 html / php 代码显示以下内容:
House# Date Time MP4 XML
45017P April 30 2019 10:21:12 45017P.mp4 45017P.xml
45017P April 30 2019 10:21:12 45017P.mp4 45031P.xml
45017P April 30 2019 10:21:12 45017P.mp4 hello.xml
45031P May 01 2019 14:56:56 45031P.mp4 45017P.xml
45031P May 01 2019 14:56:56 45031P.mp4 45031P.xml
45031P May 01 2019 14:56:56 45031P.mp4 hello.xml
hello April 30 2019 10:21:12 hello.mp4 45017P.xml
hello April 30 2019 10:21:12 hello.mp4 45031P.xml
hello April 30 2019 10:21:12 hello.mp4 hello.xml
问题陈述:
在上面的House#列的o / p中,我可以看到两个45017P
,两个45031P
和两个hello
。我想知道如何避免冗余,以便显示如下内容:
House# Date Time MP4 XML
45017P April 30 2019 10:21:12 45017P.mp4 45017P.xml
45031P May 01 2019 14:56:56 45031P.mp4 45031P.xml
hello April 30 2019 10:21:12 hello.mp4 hello.xml
