I have this regular expression in php that should find the pattern in a file name. Example: dge_ANEXO_II_F_TJ[1].pdf
But I can’t make it work.
Can someone help me?
'/[a-z]{3}_ANEXO|Anexo|anexo_[A-Za-z]{1,7}_[A-Z]{1}_[A-Z0-9]{2,5}....pdf/'

Just add parentheses in the search for anexo:
/[a-z]{3}_(ANEXO|Anexo|anexo)_[A-Za-z]{1,7}_[A-Z]{1}_[A-Z0-9]{2,5}....pdf/

More complete solution, providing the brackets:
The user @Diegofelipe posted us comments an improved solution, which changes the "wild cards" (...) by the square brackets (\[[0-9]{1}\])(notice the difference at the end):
/[a-z]{3}_(ANEXO|Anexo|anexo)_[A-Za-z]{1,7}_[A-Z]{1}_[A-Z0-9]{2,5}\[[0-9]{1}\].pdf$/
See the test on IDEONE.

If the word "attachment" is case-insensitive:
[a-z]{3}_((?i)anexo)_[A-Za-z]{1,7}_[A-Z]{1}_[A-Z0-9]{2,5}...\.pdf

A little more "short" alternative if you have rigor:
[a-z]{3}_(ANEXO|(A|a)nexo)_[A-Za-z]{1,7}_[A-Z]{1}_[A-Z0-9]{2,5}...\.pdf
