如何使用PHP显示文件夹中的图像 [英] How can one display images from a folder using PHP

问题描述

嘿所有



我的任务的一部分是显示图像。事情是图像在文件夹中，我必须从文件夹内拉出图像才能显示它，并且必须使用php完成。我必须能够从图像文件夹中提取图像才能显示它。



有人可以指出我正确的方向，或者至少让我知道如何做到这一点。我已经尝试了这组代码，但我不知道它是否会起作用，而另一件事我会收到错误



我尝试了什么：

hey all

one part of my assignment is displaying images. The things is that the images are in a folders that I have to pull the images from inside the folder for it to be display and it has to be done using php. I have to able to pull the images from the image folder in order for it to be display.

can someone point me in the right direction or at least give me an idea how to do this. I hve tried this set of codes but i have no idea if it would work and another thing i was getting errors

What I have tried:

<pre><?php

$dir_path = "folder/";
$extensions_array = array('jpg','png','jpeg');

if(is_dir($dir_path))
{
    $files = scandir($dir_path);
    
    for($i = 0; $i < count($files); $i++)
    {
        if($files[$i] !='.' && $files[$i] !='..')
        {
            // get file name
            echo "File Name -> $files[$i]<br>";
            
            // get file extension
            $file = pathinfo($files[$i]);
            $extension = $file['extension'];
            echo "File Extension-> $extension<br>";
            
           // check file extension
            if(in_array($extension, $extensions_array))
            {
            // show image
            echo "<img src='$dir_path$files[$i]' style='width:100px;height:100px;'><br>";
            }
        }
    }
}

推荐答案

dir_path = folder /;

dir_path = "folder/";

extensions_array = array（' jpg'，' png'，' jpeg'）;

if（is_dir（

extensions_array = array('jpg','png','jpeg'); if(is_dir(

dir_path））
{

dir_path)) {
