我为目录/home/pi/app创建了符号链接到/var/www/html我可以轻松地在该文件夹中显示图像
echo '<img src="/images/test.jpg"/><br />';
但是我无法使用glob函数显示该文件夹中的图像列表。
$images = glob("/images/*.jpg");
foreach($images as $image) {
echo '<img src="'.$image.'" /><br />';
}
有什么方法可以使用glob显示这些图像？如果我不能使用＆＃34; glob＆＃34;我可以使用任何功能吗？

我意识到这是一个老问题，但是我遇到了类似的问题，就我而言，我不得不在我的Apache虚拟机的import cv2
import numpy as np
def convolution_filter(gray_img, kernel):
# temporary operation
# gray_img = cv2.resize(gray_img, (10, 10))
kernel_size = len(kernel)
row = gray_img.shape[0] - kernel_size + 1
col = gray_img.shape[1] - kernel_size + 1
result = np.zeros(shape=(row, col))
for i in range(row):
for j in range(col):
current = gray_img[i:i+kernel_size, j:j+kernel_size]
multiplication = np.abs(sum(sum(current * kernel)))
result[i, j] = multiplication
return result
img = cv2.imread("input.jpeg")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
k = [[0, -1, 0], [-1, 4, -1], [0, -1, 0]]
filtered = convolution_filter(gray, k)
cv2.imwrite("filtered.jpg", filtered)
值中添加符号链接绝对路径。

但您提供的路径仅作为
存在glob()所以..
glob('c:\images\*')
查看文件系统的顶级，而不是网站文档根目录的顶级。如果您只有 glob('c:\inetpub\wwwroot\example.com\images\*');
，那么glob将查找您的脚本正在执行的任何目录的子目录。

URL中的路径名相对于服务器的文档根目录进行解释。您可以使用$_SERVER['DOCUMENT_ROOT']在PHP中获取该目录。
$images = glob($_SERVER['DOCUMENT_ROOT'] . "/imags/*.jpg");
foreach ($images as $image) {
echo '<img src="/images/'.basename($image).'" /><br />';
}
