PHP look through every root directory for keyword - php

Question

So I tried for some days to get this done. But I still don't have a single clue how i could build this code so it works. Maybe someone has an idea.
Goal: Automaticely iterate through the root-directory and any of it's subdirectories. If there's a directory, which matches the keyword it should be stored into an array.
I am only looking for directories, that's why there's a regex to exclude every object with a dot in it's name. Not perfect yet, but that's not a problem.
I ll post the first version of my code. Now it's just scanning the directory your handling to the function when calling it. Because all my other attempts are trash and this one at least works
searchformigration('/');
/* Check for related folders, that could be used for a migration */
function searchformigration($dir)
{
$scanned_elements = scandir($dir);
for($c = 0; $c <= (count($scanned_elements) - 1); $c++)
{
/* Anything but files containing a dot (hidden files, files) */
if(preg_match('/^[^.]+$/', $scanned_elements[$c]))
{
/* Checking for the keyword "Project" */
if($scanned_elements[$c] == '*Project*')
{
echo $scanned_elements[$c];
echo '</br>';
}
else
{
continue;
}
}
else
{
continue;
}
}
}

Answer 1

You can recursively retrieve files and folders with RecursiveDirectoryIterator, this will search in / for directories with 'project' in the foldername.
print_r(get_dirs('/','project'));
function get_dirs($path = '.', $search='') {
$dirs = array();
$iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::SELF_FIRST);
foreach ($iterator as $file) {
if ($file->isDir())
{
if (strpos($file->getFileName(), $search) !== false)
{
$dirs[] = $file->getRealPath();
}
}
}
return $dirs;
}

I would get all directories recursively and then grep for Project:
function searchformigration($dir) {
$results = glob($dir, GLOB_ONLYDIR);
foreach($results as $subdir) {
$results = array_merge($results, searchformigration($subdir));
}
return $results;
}
$results = preg_grep('/Project/', searchformigration('/'));
You can also do this on Linux:
exec("find / -type d -name 'Project'", $results);
