PHP scan directory with a search string

Question

Is there any way i can search a files array to match a certain string?

So i have a directory with images inside and i put them in a variable like so

$images = scandir('directory goes here');

now i want to search that images array for images with a certain name. Like for example all images with a name starting with 'cars_hatchback'.

I've tried using the glob function but it seems i'm coming up short.

Is there any way to accomplish this? Thanks in advance!

Take a look at the php's glob() function: php.net/manual/en/function.glob.php — arkascha

Use preg_grep to search an array with a pattern:

$images = scandir('directory goes here');
$result = preg_grep ("/^cars_hatchback.*/", $images);

Use glob function.

For example, if you have folder structure like this:

folder
    |----- autopass2.jpg
    |----- autopass3.png
    |----- auto_pass2.jpg
    |----- otherfile.xml

Now just use glob function with asterisk:

$result = glob('folder/autopass*');

And result is:

array
(
    0 => 'folder/autopass2.jpg'
    1 => 'folder/autopass3.png'
)

glob can be used to find filenames starting with a specific string by using an asterisk as a wildcard:

scandir('cars');

Array
(
    [0] => .
    [1] => ..
    [2] => cars_convertible1.jpg
    [3] => cars_hatchback1.jpg
    [4] => cars_hatchback2.jpg
)

glob('cars/cars_hatchback*');

Array
(
    [0] => cars/cars_hatchback1.jpg
    [1] => cars/cars_hatchback2.jpg
)
