regular expression problem

[aritaro]

hi, I am new to regular expression, i  and I would like use the preg_replace() to convert the below string:

 

 

to

 

Arg1 = abc123 !@#$ (any character)

Arg2 = only alphanumaric

 

at the beginning my reg exp is /\[code arg1=\"(.*?)\" arg2=\"(.*?)\"\]/si

and this is totally fail! and i notice that use the . (match any character) cause the problem, but the problem is the first argument support any kind of character.

 

How should i write my reg exp? help..

 

Thanks,

arita ro
