使用php的MySQL查询将数组分解为WHERE

Question

经过几个小时的修修补补，我似乎弄不明白这一点。我在数据库中有一个表，其中包含一个充满值的CSV字段。在使用php explode函数之后，我只剩下一个数组。

$emailarray = list($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

您可以像这样在查询中使用IN子句，而不是每次都遍历并发出mysql查询：

$emailarray = list($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
}
