Nearly regex with glob

Question

PHP's glob seems to support a limited-range of regex-like syntax.

I would like to catch hello<somethingherebutonlyifitbeginsby#>.txt, i.e.:

• hello.txt: ok
• hello#you.txt: ok
• hellome.txt: not ok

I tried

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

but it doesn't work. How can we correct it?

Answer 1

You can write it like that:

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

where {aa,bb} is an alternation (feature available with the GLOB_BRACE and with OSes that support it).
