Recognition of NEW LINE sign (enter)

halex

Hello,

I've posted just 10 minutes ago and I have problem with recognizing ENTER character (NEW LINE). I think that is the problem because I'm reading from one file (line by line) and at the end of every line I have comma character "," which I want to remove.
I took a substring:

$test = substr($myString,strlen($myString)-2,strlen($myString)-1);
print $test; // this print COMMA simbol ","
if ($test == ",") // this one return FALSE! Why?

Is there some trick with NEW LINE simbol because all my lines are one bellow eachother. How to recognize this simbol?

Thanks

I'm relaxed, just joking...
Well, AGAIN my fault! I put at the end of each line ", " NOT only "," so that is why it didn't working.

What a shame :-)

have a look at strrev when you got time 🙂 it's a nice function

Try...

$myString = 'this is a foobar string,';
echo strrchr($myString,',') == ',' ? 'true' : 'false';

substr() is quite nice, too. Like you can say substr($myString,-1) or substr($myString,-2)...

As for spaces and carriage returns, trim is nice too.

And one can remove end commas with regexps:
$text = preg_replace('/,\s+$/', '', $text);
