按名称和返回路径递归搜索目录

Question

I have a directory structure with up to 10 levels (may vary), given the name of the directory, I would like to return the complete path of the first directory that matches the name of the given directory.

public function LocalDirSearch($clouse) {
        $path    = $clouse[0];
        $search = $clouse[1];
        $result = $clouse[2];
        $dirs   = glob($path, GLOB_ONLYDIR);
        foreach ($dirs as $dir) {
            if(basename($dir)==$search){
                return $dir;
                break;
            }
            $this->LocalDirSearch([$dir,$search,$result]);
        }
    }

I made this script but it does not work properly I do not know what exactly it is missing and it runs indefinitely ... no error output...

Update

this the directory structure:

+--pdf
+---+---i-pdf-0034
+---+---+---form
+---+---+---+---data
+---+---+---+---other
+---+---i-pdf-0045
+---+---+---form
+---+---+---+---data
+---+---+---+---other
+---+---i-pdf-0056
+---+---+---form
+---+---+---+---data
+---+---+---+---other
+--doc
+---+---i-doc-0034
+---+---+---form
+---+---+---+---data
+---+---+---+---other
+---+---i-doc-0045
+---+---+---form
+---+---+---+---data
+---+---+---+---other
+---+---i-doc-0056
+---+---+---form
+---+---+---+---data
+---+---+---+---other

function call:

$this->LocalDirSearch(['C:/xampp/htdocs/files','i-pdf-0045']);

Script to search directory:

public function LocalDirSearch($clouse) {
    $path   = $clouse[0];
    $search = $clouse[1];
    $dirs = glob($path . '/*', GLOB_ONLYDIR);
    foreach ($dirs as $dir) {
        if (basename($dir) == $search) {
            return $dir;
        }else{
            // return the result of the recursive call
            return $this->LocalDirSearch([$dir, $search]);  
        }
    }
}

Ouput of recursive print nav in directory:

'C:/xampp/htdocs/files/'
'C:/xampp/htdocs/files/pdf/'
'C:/xampp/htdocs/files/pdf/i-pdf-0034/'
'C:/xampp/htdocs/files/pdf/i-pdf-0034/form/'
'C:/xampp/htdocs/files/pdf/i-pdf-0034/form/data/' #out of search

Return:

'NULL'

Answer 1

Two main problems:

1. You don't provide a pattern for glob that will return any subdirectories
2. You don't return the result of the recursive call

which means it will never find your target (unless your target happens to be the directory you start in), so it will never return.

Try making the following changes

public function LocalDirSearch($clouse) {
    $path    = $clouse[0];
    $search = $clouse[1];
    $result = $clouse[2];

    // add a wildcard to the glob pattern so it will match everything under $path
    $dirs   = glob($path . '/*', GLOB_ONLYDIR);

    foreach ($dirs as $dir) {
        if (basename($dir)==$search){
            return $dir;
        }

        // return the result of the recursive call
        if ($subdir = $this->LocalDirSearch([$dir, $search, $result])) {
            return $subdir;
        }
    }
}

Incidentally, break is unnecessary after return , and $result does not appear to be used in the function.
