问题描述

我有一个脚本和一个函数，该脚本可以获取该文件夹中的每个文件.如何编辑此代码以使其仅获取.png文件?

I have a script and a function in it gets every file in that folder. How can I edit this code to make it so it only gets .png files?

public function GetPreviews($category)
    {
        $directories = glob("assets/preview/$category/*");
        $directory = array();
        foreach($directories as $directories)
        {
            $directory[] = str_replace("assets/preview/$category/", "", $directories);   
        }
        return $directory;      
    }

推荐答案

将.png添加到glob("assets/preview/$ category/*.png");

add .png to glob("assets/preview/$category/*.png");

public function GetPreviews($category)
    {
        $directories = glob("assets/preview/$category/*.png");
        $directory = array();
        foreach($directories as $directories)
        {
            $directory[] = str_replace("assets/preview/$category/", "", $directories);   
        }
        return $directory;      
    }
