PHP递归目录路径 [英] PHP recursive directory path
本文介绍了PHP递归目录路径的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这个功能返回完整目录树
:
function getDirectory( $path = '.', $level = 0 ){
$ignore = array( 'cgi-bin', '.', '..' );
// Directories to ignore when listing output. Many hosts
// will deny PHP access to the cgi-bin.
$dh = @opendir( $path );
// Open the directory to the handle $dh
while( false !== ( $file = readdir( $dh ) ) ){
// Loop through the directory
if( !in_array( $file, $ignore ) ){
// Check that this file is not to be ignored
$spaces = str_repeat( ' ', ( $level * 4 ) );
// Just to add spacing to the list, to better
// show the directory tree.
if( is_dir( "$path/$file" ) ){
// Its a directory, so we need to keep reading down...
echo "<strong>$spaces $file</strong><br />";
getDirectory( "$path/$file", ($level+1) );
// Re-call this same function but on a new directory.
// this is what makes function recursive.
} else {
echo "$spaces $file<br />";
// Just print out the filename
}
}
}
closedir( $dh );
// Close the directory handle
}
但我想做的是搜索文件/文件夹并返回它的路径,我该怎么办?你有这样的功能,还是给我一些如何做的提示?
but what i want to do is to search for a file/folder and return it's path, how can i do that? do you have such a function or can you give me some tips on how to do this?
推荐答案
尝试使用 RecursiveIteratorIterator 与 RecursiveDirectoryIterator
$path = realpath('/path/you/want/to/search/in');
$objects = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
if($object->getFilename() === 'work.txt') {
echo $object->getPathname();
}
}
