使用nl2br的PHP JSON编码

Question

the following code I use to populate t able via AJAX -

    $sql = "SELECT * FROM web_task_comments WHERE web_task_id = '$taskId' 
            ORDER BY log_date DESC";
    $result = mysql_query($sql)or die(mysql_error());
    if (mysql_num_rows($result) > 0) {
        while($obj = mysql_fetch_object($result)) {
            $arr[] = $obj;      
        }
        echo json_encode($arr);
    }

There is a row in the DB that will need nl2br() and then pass that back to AJAX request. How do I do this with my current setup? Can you use MySQL to convert nl to br in the query?

Thanks Rory

您可以使用MySQL的REPLACE功能将所有换行符和回车符\\n和\\r\\n替换为<br /> ： http : //dev.mysql.com/doc/refman/5.1/de/replace.html
