我有一个小问题,这是我的代码,用于列出文件夹和子文件夹中的所有文件;
if ($handle = opendir($dir)) {
$allFiles = array();
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
if (is_dir($dir . "/" . $entry)){
$allFiles[] = "D: " . $dir . "/" . $entry;
}else{
$extension = strtoupper(pathinfo($entry, PATHINFO_EXTENSION));
$fileNoExten = pathinfo($entry, PATHINFO_FILENAME);
$directory = substr(str_replace('/', ' > ', $dir), $rootLenOnce + 3);
$listagem .= '<tr>';
$listagem .= "<td><a href='../" . $dir . "/" . $entry . "' ' target='_blank'>" . $entry . "</a></td>";
//$listagem .= "<td><small>" . $directory . "</small></td>";
$listagem .= "<td>" . $extension . "</td>";
$listagem .= "<td><a class='download-cell' href='../".$dir ."/". $entry."' ' download> <i class='fa fa-download' ></i></a></td>";
$listagem .= "<td class='display-none'>" . $fileNoExten . "</td>";
$allFiles[] = "F: " . $dir . "/" . $entry;
$listagem .= '</tr>';
echo "<pre>"; print_r(glob("*.pdf")); echo "</pre>";
}
}
}
closedir($handle);
foreach($allFiles as $value){
$displayName = substr($value, $rootLen + 4);
$fileName = substr($value, 3);
$linkName = str_replace(" ", "%20", substr($value, $pathLen + 3));
if (is_dir($fileName)) {
myScanDirPdf($fileName, $level + 1, strlen($fileName),$rootLenOnce);
}
}
}
return $listagem;
}
我需要过滤搜索结果,仅搜索.pdf文件。
有人可以帮助我!
谢谢!
我尝试使用glob函数,但效果不佳。
谢谢!
答案 0 :(得分:0)
遍历每个文件时,可以使用
if(stripos($fileName, ".pdf"))
希望这会有所帮助
在列出所有文件和子文件夹时,我还有一个建议。 您可以使用递归迭代器
$folderName = $_POST['folderName'];
$dir = new RecursiveDirectoryIterator($folderName);
$it = new RecursiveIteratorIterator($dir);
foreach ($it as $fileinfo) {
if ($fileinfo->isDir()) {
}elseif ($fileinfo->isFile()) {
$fileName = $fileinfo->getFileName();
if(stripos($fileName, ".pdf")) {
//do what you need to do
}
}
}
