str_replace ? \r

[Sam Smith <php@xxxxxxxx>]

>From a <textarea> on a web form I'm attempting to convert all returns(\r),
from the users input, to "<br />", for db INSERT, and then back again for
display in the <textarea>. (They remain as <br />s for normal HTML web page
display.)

code:
// From textarea to db UPDATE
function addBR($tv) {
    $tv = addslashes($tv);
    $tv = str_replace("\r","<br />",$tv);
//  $tv = preg_replace("/(\r\n|\n|\r)/", "<br />", $tv);
//  $tv = preg_replace("/(\r\n|\n|\r)/", "", $tv);
    return $tv;}

// For display in <textarea>
function remBR($tv) {
    $tv = str_replace("<br />","\r",$tv);
    $tv = stripslashes($tv);
    return $tv;
}

IT ALL works fine accept if a return is entered in the form's <textarea> at
the very beginning:

mysql> SELECT jbs_jobDesA FROM jobs WHERE jbs_ID=77 \G
*************************** 1. row ***************************
jbs_jobDesA: <br />[the return is still here]
Lesequam coreet la feum nulla feu facil iriure faccummolut ulput num augait
1 row in set (0.00 sec)

the return is converted to <br />\r (leaving the return). AND then when
converted back for for the <textarea> both are stripped out, that is, there
is nothing in front of the first character. When resubmitted for UPDATE:

 mysql> SELECT jbs_jobDesA FROM jobs WHERE jbs_ID=77 \G
*************************** 1. row ***************************
jbs_jobDesA: Lesequam coreet la feum nulla feu facil iriure faccummolut
ulput num augait 
1 row in set (0.00 sec)

Q. Why is that first return treated differently? All other returns are
treated as expected.

Thanks,
sam
