当目录名称带有方括号“[]”等特殊字符时，Glob 不起作用

Question

I have issue while using glob function when path directory with square brackets.

// Example 1 - working
$path = 'temp'. DIRECTORY_SEPARATOR .'dir - name';
$files = glob($path . DIRECTORY_SEPARATOR . '*.txt');
// List all files 
echo '<pre>';
    print_r($files);
echo '</pre>';

Above code is working but when directory name with square brackets like dir[name] or dir - [name] then its not working.

// Example 2 - not working
$path = 'temp'. DIRECTORY_SEPARATOR .'dir - [name]';
$files = glob($path . DIRECTORY_SEPARATOR . '*.txt');
// result got empty if file on that directory 
echo '<pre>';
    print_r($files);
echo '</pre>';

Answer 1

Thanks for all of you.

I got exact solution for my query. below code is a working for me

$path = 'temp'. DIRECTORY_SEPARATOR .'dir - [name]';
$path = str_replace('[', '\[', $path);
$path = str_replace(']', '\]', $path);
$path = str_replace('\[', '[[]', $path);
$path = str_replace('\]', '[]]', $path);
$files = glob($path . DIRECTORY_SEPARATOR . '*.txt');
// List files
echo '<pre>';
    print_r($files);
echo '</pre>';

Answer 2

This is what I use:
$path = str_replace(['[',']',"\\f[","\\f]"], ["\\f[","\\f]",'[[]','[]]'], $path);

All in one line.

Answer 3

[foo] has a special meaning, it represents a character class (regular expression syntax).

So to have [ and ] mean square brackets literally , you have to escape them – by preceding them with a backslash.

Answer 4

Try

$path = 'temp'. DIRECTORY_SEPARATOR .'dir - [name]';
$from = array('[',']');
$to   = array('\[','\]');
$files =glob(str_replace($from,$to,$path . "\\*.txt"));
echo '<pre>';
    print_r($files);
echo '</pre>';

Answer 5

Late to the party I know, but based on previous answers, and after testing on both Linux/Mac and Windows, I came up with this utility function:

function glob_escape($path){
  return preg_match('/\[.+]/', $path) ? str_replace(['[',']', '\[', '\]'], ['\[','\]', '[[]', '[]]'], $path) : $path;
}

For practical reasons, the function only attempts to escape characters when there are opening and closing [brackets] in the $path , with minimum one character in between. Single-brackets some[folder and brackets without a char between some[]folder don't need to be escaped.

Usage example:

$path = 'some/dir[brackets]here/more[brackets]blah';
glob(glob_escape($path) . '/*', GLOB_NOSORT|GLOB_ONLYDIR);

Tested on Linux and Windows.
