PHP list directory structure and exclude some directories

Question

I have this PHP code:

$rootpath = '../admin/';
$inner = new RecursiveDirectoryIterator($rootpath);
$fileinfos = new RecursiveIteratorIterator($inner);

foreach ($fileinfos as $pathname => $fileinfo)
{
    $pathname2 = substr($pathname,2);
    $sql = "SELECT * from admin_permissions where page_name = '$pathname2'";
    $rs = mysql_query($sql,$conn);
    if (mysql_num_rows($rs) == 0)
    {
        if (!$fileinfo->isFile()) continue;
        $sql2 = "INSERT into admin_permissions (page_name) values ('$pathname2')";
        $rs2 = mysql_query($sql2,$conn);
        echo "$pathname<br>";
    }
}

This displays my directory structure and inserts directories and file names into the database (deleting the first two characters ..).

Since RecursiveDirectoryIteratoriterates over all files in all directories, how can I exclude whole directories, including all files inside them?

Answer 1

In essence, my answer is not much different than Thomas . However, he does not get a few correct things:

• The semantics correct for RecursiveCallbackFilterIteratorrequire return truefor recursion to subdirectories.
• . ..
• in_array ,

^{: 2 ; - , , .}

<?php

$directory = '../admin';

// Will exclude everything under these directories
$exclude = array('.git', 'otherDirToExclude');

/**
 * @param SplFileInfo $file
 * @param mixed $key
 * @param RecursiveCallbackFilterIterator $iterator
 * @return bool True if you need to recurse or if the item is acceptable
 */
$filter = function ($file, $key, $iterator) use ($exclude) {
    if ($iterator->hasChildren() && !in_array($file->getFilename(), $exclude)) {
        return true;
    }
    return $file->isFile();
};

$innerIterator = new RecursiveDirectoryIterator(
    $directory,
    RecursiveDirectoryIterator::SKIP_DOTS
);
$iterator = new RecursiveIteratorIterator(
    new RecursiveCallbackFilterIterator($innerIterator, $filter)
);

foreach ($iterator as $pathname => $fileInfo) {
    // do your insertion here
}

Answer 2

RecursiveCallbackFilterIterator.

$directory = '../admin/';
$filter = array('.git');

$fileinfos = new RecursiveIteratorIterator(
  new RecursiveCallbackFilterIterator(
    new RecursiveDirectoryIterator(
      $directory,
      RecursiveDirectoryIterator::SKIP_DOTS
    ),
    function ($fileInfo, $key, $iterator) use ($filter) {
      return $fileInfo->isFile() || !in_array($fileInfo->getBaseName(), $filter);
    }
  )
);

foreach($fileinfos as $pathname => $fileinfo) {
  //...
}

:

$excludes = array(
    'files' => array('file1.ext','file2.ext','fileN.ext'),
    'dirs' => array('dir1','dir2','dirN')
);

foreach ($directories as $current_dir) {
    if (!in_array($current_dir,$excludes['dirs'])) {
       // directory method
       foreach ($files as $current_file) {
            if (!in_array($current_file,$excludes['files'])) {
              // files method
            }
        }
    }
}

Answer 6

RecursiveFilterIterator dirs, fooreach dirs.

class MyDirFilter extends RecursiveFilterIterator {
    public function accept() {

        $excludePath = array('exclude_dir1', 'exclude_dir2');
        foreach($excludePath as $exPath){
            if(strpos($this->current()->getPath(), $exPath) !== false){
                return false;
            }
        }
        return true;

    }
}

$rootpath = '../admin/';
$dirIterator = new RecursiveDirectoryIterator($rootpath);
$filter   = new MyDirFilter($dirIterator);
$fileinfos   = new RecursiveIteratorIterator($filter);

foreach($fileinfos as $pathname => $fileinfo)
{
    // only accepted dirs in loop
}

Just use for validation function is_filein your foreach

for example

foreach ($fileinfos as $pathname => $fileinfo)
{

    if (!is_file($pathname)) 
    {
         continue;// next step
    }
    $pathname2 = substr($pathname,2);
    ...
}
