MySQL查询使用php爆炸数组作为WHERE

Question

经过几个小时的修修补补，我似乎无法弄明白这一点。我在数据库中有一个表，其中包含一个充满值的CSV字段。使用php explode函数后，我留下了一个数组。

$emailarray = list($email) = explode(",", $csv);


while($arrayreadable = mysql_fetch_array($emailarray,$emailcount[0])){



$makefeed = mysql_query("SELECT email,name FROM $statusdatabase WHERE email = $arrayreadable[`0`]'");
while ($friendfeedget = mysql_fetch_assoc($makefeed)) {

[Code for what I want the loop to do]

}


}

Answer 1

不是每次循环并发出mysql查询，而是可以在查询中使用IN子句，如下所示：

$emailarray = list($email) = explode(",", $csv);
$emails = implode(',', $emailarray);

$makefeed = mysql_query("SELECT email,name FROM $statusdatabase WHERE email IN ('".$emails."')");

while ($friendfeedget = mysql_fetch_assoc($makefeed)) {
  // code
}
