PHP - while循环更改

Question

我有跟随while循环。

$readNews_SQLselect = "SELECT  ";
$readNews_SQLselect .= "id, content ";  // rows names
$readNews_SQLselect .= "FROM ";
$readNews_SQLselect .= "news ";         // table name


$readNews_SQLselect_Query = mysql_query($readNews_SQLselect);   

//$indx = 1;    
while ($row = mysql_fetch_array($readNews_SQLselect_Query, MYSQL_ASSOC)) {
    $ID = $row['id'];
    $CONTENT = $row['content'];

    echo '<li>' . $ID .' ' . $CONTENT . '</li>';

    //$indx++;

}

mysql_free_result($readNews_SQLselect_Query);

如果我添加'$LIVE = $row['live'];'的条件是只显示live值字符串为'0'的行？实时将是0/1 （VARCHART）。

任何建议都非常感谢。

Answer 1

只需将其添加到您的查询中：

$readNews_SQLslect .= " WHERE live = '0'";

Answer 2

改变$readNews_SQLselect

$readNews_SQLselect = "SELECT  ";
$readNews_SQLselect .= "id, content ";   // rows names
$readNews_SQLselect .= "FROM ";
$readNews_SQLselect .= "news ";          // table name
$readNews_SQLselect .= "WHERE live='0'"; // condition

Answer 3

1. 改变你的sql：

   $readNews_SQLselect = "SELECT  ";
   $readNews_SQLselect .= "id, content ";  // rows names
   $readNews_SQLselect .= "FROM ";
   $readNews_SQLselect .= "news ";         // table name
   $readNews_SQLselect .= "where live = '0' "; 

2. 如果条件：

   if ($row['live'] == '0') { echo '<li>' . $ID .' ' . $CONTENT . '</li>'; }
