remove excess carriage returns

[nearo]

OK.. here it is. I have elements coming in from an array, submitted from an HTML textarea form. I can get the individual elements formated the way I want (each newline is a new element), but I am having trouble eliminating excess carriage returns.

The extra carriage returns come in as seperate array elements, I can eliminate them, but the complete array then becomes only one string or element. How do I remove ONLY the excess or accidental carriage returns, but keep the ones that seperate each array element? Thank you!

What you could do is remove all CRLF and wordwrap your text then use LF as your defining break in wordwrap

Or you could just remove hard returns with something like this

$text = preg_replace("/[\r]/","",$text);

Maybe none of these will be right for you but look at PHP's string functions

Thank you for the advice. Im trying to figure out how to remove only excess hard returns. I have a textarea input, and I want each newline to be a new element of the array, except for extra-empty new lines.

I know its possible.... but how? 🙂

Read all the lines into the array as you are, then filter out the empty lines:

function is_nonempty($string)
{ return $string!='';
}

So now you can say:
$array=array_filter($array,'is_nonempty');
