[Resolved] Converting line breaks

[Reformed]

I have a function that converts line breaks into <br> tags when a user hits the enter key in a text field. I now need to remove that tag when a user chooses to edit the same text region. It comes back with the <br> tag and then it adds an additional <br> tag upon re-submission, not good.

I need to convert <br> characters to \n characters when the user elects to edit the content in the text box. I need to do this to one variable in a large array. I'm using the preg_match function to remove <br> charaters and replace them with \n characters for display in the text box, but on a large array, this does not work. Any suggestions?

Well, I posted too soon. I figured out my problem. I did notice that there is not a ton of info on converting line breaks in the forum, so to avoid being that guy who asks a question and then takes the trouble to come back to the forum to say he figured it out, but neglects to describe how he fixed the problem, I shall explain the solution to mine.

If you need to convert line breaks in a text area from /n (aka carriage returns from the enter key) charaters to <br> characters, you only need to do this one time and its on the display part of your script. You don't have to to a preg_replace when inputting the text, only when you display the text. After your query just apply this to the particular variable in the array.

$result[0][16] = preg_replace('/\n/', '<br>', $result[0][16]);

I know this is very simple and many out there wil say, "duh", but I figured I'd elaberate.

a shortcut:

nl2br() = New Line 2 Break

$result[0][16] = nl2br($result[0][16]);
