几乎正则表达式与 glob

Question

PHP的glob好像支持limited-range of regex-like syntax.

我想赶上hello<somethingherebutonlyifitbeginsby#>.txt，即：

hello.txt: 好的
你好#you.txt: 好的
hellome.txt: 不行

我试过了

glob('hello#?*.txt', GLOB_BRACE);

但它不起作用。我们如何纠正它？

Answer 1

glob's regex also supports character classes and negative character classes, using the syntax [] and [^]. It will match any one character inside [] or match any one character that is not in [^].
hello.txt: ok
hello#you.txt: ok
hellome.txt: not ok

//[] include chars. and #
var_dump(glob('hello[.#]*txt', GLOB_BRACE));

array(2) {
[0]=>
 string(13) "hello#you.txt"
[1]=>
 string(9) "hello.txt"
}


>ls hello* 
hellome.txt  hello.txt  hello#you.txt

Answer 2

你可以这样写：

glob('hello{#*,}.txt', GLOB_BRACE);

其中 {aa,bb} 是一个替代（GLOB_BRACE 和支持它的操作系统可用的功能）。
