regex question

I notice all regex in PHP begins with / character. Does this signal the beginning of line? preg_match('/abc 12(de)??/','xxxyyy abc 12de, gghh',$result); var_export($result); will yield array (0=>'abc 12',) while preg_match('/abc 12(de)?/','xxxyyy abc 12de, gghh',$result); var_export($result); will y...

confused with statement

Code: Select all

echo $a = $b == $b;
I don't understand this code. Is it comparison or assignment? but it can be printed. Can anybody explain? thanks

\n problem

AFAIK, \n is global convention for newline. but

Code: Select all

echo 'a\nb';
produces a\nb
and

Code: Select all

echo "a\nb";
produces ab

Can anybody explain this behavior? and how can one print newline character? I've always used <br>. thanks

Re: what's the difference?

thanks for the reply requinix, does this mean I use :: only when referring to any static functions or members only? what's the side effect if I use :: to call instance member and functions?

what's the difference?

What's the different effect when accessing member using

Code: Select all

$this::doIt();
and

Code: Select all

$this->doIt();

debugging in PHP

How can I debug in PHP? I'm using Eclipse PDT, and I wish to see the execution steps line per line like F6 in Java Debug As. Thank you.

what's the point of function &do_job()?

what's the point of the superfluous ampersand in &do_job? as far as I know, PHP starting from 5 always return reference instead of value? what's the purpose of this (assuming I'm creating brand new app with 5.4 with no need for backward compat).

Re: Whats Your Security Regimen ?

what about DB code 2? is it free of SQL injection? even without calling sanitizeInput at all?
also, I put critical files outside web root, is there any way at all to access those critical files via browser? or is it safe already?

Re: access protected file without include

Could you please explain more about this 'secure coding'? are you referring to sanitizing?
