这与List of emails, delete rows out of a table有关,我使用Marc的解决方案删除用txt文件写的电子邮件列表,这是
$addresses = file('emails.txt');
foreach($addresses as $address) {
$safe_address = mysql_real_escape_string($address);
$sql = "DELETE FROM customer WHERE (email = '$safe_address');";
$result = mysql_query($sql) or die(mysql_error());
}
我有txt文件,其中每封电子邮件都写在一行上。但是,当我应用上述解决方案时,它只删除在该txt文件的最后一行写的一封电子邮件。
我在这里做
$addresses = file('emails.txt');
foreach($addresses as $address) {
$safe_address = mysql_real_escape_string($address);
echo $safe_address;
}
它给出了

我尝试使用explode函数来获取\ r \的红色,因此匹配记录并删除所有记录,但没有运气。
请有人提出建议以达到目标。感谢

试一试
$sql = "DELETE FROM customer WHERE (email = '$safe_address');";
替换为
$sql = "DELETE FROM customer WHERE email = '$safe_address' ";
