PHP中文件匹配的全局模式-获取不以字符串组开头的目录内容

Question

如何忽略所有以字符串"blogCover"开头的图像

一开始我没有排除测试的图片

img目录中的所有图片：

$imgDir = 'img';
$imgs = glob($imgDir.'/*{.jpg}', GLOB_BRACE); //all images!
echo'<pre>'; print_r($imgs); echo'</pre>';

结果：

Array
(
[0] => img/blogCover-large.jpg
[1] => img/blogCover-large_2x.jpg
[2] => img/blogCover-medium.jpg
[3] => img/blogCover-medium_2x.jpg
[4] => img/blogCover-small.jpg
[5] => img/blogCover-small_2x.jpg
[6] => img/boddy-large.jpg
[7] => img/boddy-large_2x.jpg
[8] => img/boddy-medium.jpg
[9] => img/boddy-medium_2x.jpg
[10] => img/boddy-small.jpg
[11] => img/boddy-small_2x.jpg
[12] => img/face-large.jpg
[13] => img/face-large_2x.jpg
[14] => img/face-medium.jpg
[15] => img/face-medium_2x.jpg
[16] => img/face-small.jpg
[17] => img/face-small_2x.jpg
[18] => img/hand-large.jpg
[19] => img/hand-large_2x.jpg
[20] => img/hand-medium.jpg
[21] => img/hand-medium_2x.jpg
[22] => img/hand-small.jpg
[23] => img/hand-small_2x.jpg
[24] => img/head-large.jpg
[25] => img/head-large_2x.jpg
[26] => img/head-medium.jpg
[27] => img/head-medium_2x.jpg
[28] => img/head-small.jpg
[29] => img/head-small_2x.jpg
)

我的目标：忽略所有以字符串"blogCover"开头的图像

$imgDir = 'img';
$imgs = glob($imgDir.'/*{[!blogCover*].jpg}', GLOB_BRACE);
echo'<pre>'; print_r($imgs); echo'</pre>';

意外结果：

Array
(
[0] => img/blogCover-large_2x.jpg
[1] => img/blogCover-medium.jpg
[2] => img/blogCover-medium_2x.jpg
[3] => img/blogCover-small_2x.jpg
[4] => img/boddy-large_2x.jpg
[5] => img/boddy-medium.jpg
[6] => img/boddy-medium_2x.jpg
[7] => img/boddy-small_2x.jpg
[8] => img/face-large_2x.jpg
[9] => img/face-medium.jpg
[10] => img/face-medium_2x.jpg
[11] => img/face-small_2x.jpg
[12] => img/hand-large_2x.jpg
[13] => img/hand-medium.jpg
[14] => img/hand-medium_2x.jpg
[15] => img/hand-small_2x.jpg
[16] => img/head-large_2x.jpg
[17] => img/head-medium.jpg
[18] => img/head-medium_2x.jpg
[19] => img/head-small_2x.jpg
)

所有'*-legal.jpg'、'*-small.jpg'图像都缺少

预期结果：

Array
(
[0] => img/boddy-large.jpg
[1] => img/boddy-large_2x.jpg
[2] => img/boddy-medium.jpg
[3] => img/boddy-medium_2x.jpg
[4] => img/boddy-small.jpg
[5] => img/boddy-small_2x.jpg
[6] => img/face-large.jpg
[7] => img/face-large_2x.jpg
[8] => img/face-medium.jpg
[9] => img/face-medium_2x.jpg
[10] => img/face-small.jpg
[11] => img/face-small_2x.jpg
[12] => img/hand-large.jpg
[13] => img/hand-large_2x.jpg
[14] => img/hand-medium.jpg
[15] => img/hand-medium_2x.jpg
[16] => img/hand-small.jpg
[17] => img/hand-small_2x.jpg
[18] => img/head-large.jpg
[19] => img/head-large_2x.jpg
[20] => img/head-medium.jpg
[21] => img/head-medium_2x.jpg
[22] => img/head-small.jpg
[23] => img/head-small_2x.jpg
)

我希望忽略这些图片：

• blogCover-large.jpg
• blogCover-large_2x.jpg
• blogCover-mediam.jpg
• blogCover-mediam_2x.jpg
• blogCover-small.jpg
• blogCover-small2.x.jpg

Answer 1

正确的语法是：

$imgs = glob($imgDir.'/[^blogCover]*.jpg', GLOB_BRACE);
