How would I search a directoy for a filename not it's contents in PHP?_问答_开发者

Alright I have several hundred different files in multiple directory under one main directory called Files. How would I create a PHP fil开发者_开发知识库e inside the root directory (FIles) ands earch all sub-directories etc and then print the results to the user? However, I only want this search engine to search the filename and not it's contents. If possible could you provide a script already made or sample code? Thanks a lot!

To search for files in PHP, you can use glob:

http://php.net/manual/en/function.glob.php

To get a file listing for a path, you can use scandir:

http://php.net/manual/en/function.scandir.php

Example

$dir = "/path/to/search/in/*.txt"; //search a path for only .txt files
foreach(glob($dir) as $file)  
{
    //print out the files that match
    echo "filename: $file : filetype: " . filetype($file) . "<br />";
}

Custom Recursive Glob

From: http://snipplr.com/view.php?codeview&id=16233

rglob($pattern, $flags = 0, $path = '')
{
    if (!$path && ($dir = dirname($pattern)) != '.')
    {
        if ($dir == '\\' || $dir == '/') $dir = '';
            return rglob(basename($pattern), $flags, $dir . '/');
    }
    $paths = glob($path . '*', GLOB_ONLYDIR | GLOB_NOSORT);
    $files = glob($path . $pattern, $flags);
    foreach ($paths as $p) $files = array_merge($files, rglob($pattern, $flags, $p . '/'));
    return $files;
}

PHP5:

$dir_iterator = new RecursiveDirectoryIterator("/path");
$iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);
// could use CHILD_FIRST if you so wish

foreach ($iterator as $file) {
    echo $file, "\n";
}
