Question

i)

$row4 = mysql_fetch_array($sql_res);

谁能帮助我如何获得<代码>$row4 [ response ]的随机值?

the $row4 does not have constant values...
but for now $row4 contains

Array ( [0] => 3 [id] => 3 [1] => where is dryad [react] => where is dryad [2] => Dryad is found in the farthest part of the Dark wilderness. [response] => Dryad is found in the farthest part of the Dark wilderness. [3] => [review] => ) 1

既然你现在的法典是正确的,你只能接回一排。这一增长只是含有你的实地价值观。如果你确实试图从这一单一渠道获得随机的实地价值,你将使用:

$randomKey = array_rand($row4,1);

如果你打算要求从你的询问中随机浏览,你可以采取两种方式之一:

(1) 使用<条码>条码_rand,以 gr取一条任意的行文,并放置在<条码>上 Row:

while($row = mysql_fetch_array($sql_res)) $rows[] = $row;
$randomRow = array_rand($rows);

2) 在您的询问中,你可以具体指出,只剩下1个断层,而不是每个结果:
