[RESOLVED] glob() question: getting an array of filenames.

Joseph_Sliker

Hi;

Okay, say I have a bunch of pictures in directory/subdirectory "groups/photos/" with names like "group1_00.jpg", "group1_01.jpg", "group1_03.jpg", (and similar sets for group2, group3, etc.)

I understand how to get a filtered set of filenames from the target directory into an array via a command like this:

$groupID="group1"; //(a variable value passed from a form or link)
$filenames=glob("groups/photos/".$groupID."*.{jpg,JPG,jpeg,JPEG}", GLOB_BRACE);

The resulting array will contain values pre-pended with the directory/subdirectory string like this. "groups/photos/group1_00.jpg", "groups/photos/group1_01.jpg", "groups/photos/group1_03.jpg". I DON'T want that. I know I can strip the directory strings off after the fact with ltrim() but I was wondering if there is a way to do the initial request for the array into the specific subdirectory without returning that part of the string into the array.

ie. I want a command something like:
$filenames=glob("groups/photos/".$groupID."*.{jpg,JPG,jpeg,JPEG}", GLOB_BRACE);
to return:
$filenames=array("group1_00.jpg", "group1_01.jpg", "group1_03.jpg")

One alternative would be to use basename(), perhaps as part of an array_map()?

Another is to just change to the directory.

$fileDir = "/path/to/files/of/interest"
$curDir = getcwd();
chdir($fileDir);
$files = glob("*.jpg");
chdir($curDir);

Hmm. Those look interesting. I will try them later.

I went ahead with the following in my script and it seems to do the job with minimal code.

$dir_filenames=glob("groups/photos/".$id."*.{jpg,JPG,jpeg,JPEG}", GLOB_BRACE);  

foreach($dir_filenames as $stripped) {$filenames[]=ltrim($stripped, "groups/photos/");}

Just for the sake of slightly simpler code, you could change that to:

$filenames=glob("groups/photos/".$id."*.{jpg,JPG,jpeg,JPEG}", GLOB_BRACE);  

foreach($filenames as &$name) {  // note use of "&"
    $name = basename($stripped);
}

But I'm not going to lose any sleep if you leave it the way it is. 😉

If we're going for simple code...

// You get this...
$array = array( "groups/photos/group1_00.jpg", "groups/photos/group1_01.jpg", "groups/photos/group1_03.jpg" );

// But, presto chango...
$array = array_map( 'basename', $array );

Resulting array:

Array
(
    [0] => group1_00.jpg
    [1] => group1_01.jpg
    [2] => group1_03.jpg
)

glob() golf!

array_map('basename',$files=glob('/users/nogdog/pictures/*.jpg'));

Y'see, THIS is why I hang out here rather than beating my head against WordPress and other systems for "easy" creation of websites!

Thanks so much!
