Need to understand the value , I get it partially like it's said the character from A to Z and a to z and 0 to 9 but I did not get g stands for what and also the symbols? is it character or is it symbol please help.

Answer 1

FYI, here are the list of modifiers:
i => case insensitive
g => global
m => multiline
u => unicode

Answer 2

That's the flag g -> global, m-> multiline etc.

Answer 3

this is a regex that matches any non-alphanumeric characters. ("^" means negated character class, the letters and numbers signify all capital and lowercase letters and digits, and the "g" is just a flag for global as said in the previous comment)
