我有此功能返回full directory tree
:
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
}
但是我想做的是搜索文件/文件夹并返回它的路径,我该怎么做?你有这样的功能,或者可以给我一些技巧吗?
最佳答案
尝试结合使用RecursiveIteratorIterator和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();
}
}
