[RESOLVED] Dots versus Commas

[ajar]

I have yet another question. What is the difference between using dots or commas. I got some help with a script I'm using and the person used dots where I originally used commas. The script is working fine, but I'm trying to learn to write good code instead of just code that works. If there's something bad about using the dots, I'd like to know how to fix my script so it's right.

can you post an example?

I assume you mean for concatenation? You cannot concatenate in PHP with commas, only dots (periods) ( " . " ). Does that answer your question? Or is it something else?

mail( "[e-mail]", "Subject Line",  "\rName: $name\n" . "\rDay Phone: $day\n" .  "\rEvening Phone: $evening\n" . "\rBest time to contact you: $contacttime\n" . "\rQuestions or Comments: $comments\n",
      "From: " . $email . "\r\n" );

Here's an example. I think LoganK answered my question, though.

Thank you.

The only thing I can think of that can use both is in echo statements like

echo 'hello ', $username, ' how you doin?';

where you could use dots instead if you wanted. I use commas as they're very slightly quicker than using dots. The only annoyance is that when you're prototyping a function and echoing everything out, then decide to return the contents as a string you have to change all the commas to dots

Thanks so much. That is extremely useful information. Thanks to everyone for the help.

Hmmm...I never knew you could use commas in PHP as conjoiners....you learn something new every day!
