Once you've got a syntax highlightning engine such as net.sf.colorer, for example, reading "strings $like being $this or $that" is easier and faster than 'strings '.$like.'being '.$this.'or '.'$that' and there is more chances to spot a mistake like I did here on coding stage. And since it is also faster to type it makes one of PHP features, what makes coding in PHP differ from JS in a better way. Since none of you provided any links, I still do not see any grounds why to stick with single quotes. Considering PEAR is a central place for a quality code and your desire to ought everyone follow these rules, maybe it is time to prove your words and make a research? Justin? P.S. Guys, how about to relax CS a bit and make all other "coding practices" OFFTOPIC so the people calm down eventually? Where is this tracker where I could post a report about how I am bugged with those? WBR.techtonik -- (B)uilding, (A)ntenna, (S)pan and (E)arth * terminal velocity - 54m/s, 305m *
