为while循环结果创建一个变量

$fruits = \'\';
while ($topic = mysql_fetch_assoc ($result)); {
    $fruits .= \"{$topic[\"overtag \"]} \";
}

// I love arrays.
$fruits = array();
while ($topic = mysql_fetch_assoc ($result)); {
   $fruits[] = (string)$topic[\"overtag \"];
}

// If you don\'t want an array, but a string instead, use implode:

$fruits = implode(\' \', $fruits)

$fruits = \"\";
while ($topic = mysql_fetch_assoc ($result)); {
  echo \"{$topic[\"overtag \"]} \";
  $fruits .= $topic[\'overtag\'] . \" \";
}
// This is going to result in an extra space at the end, so:
$fruits = trim($fruits);

while ($topic = mysql_fetch_assoc ($result)); {
                                   --------^^^--
