好的，我的站点中有一个while循环函数，它可以提取excel文档并将其解析到我想要检查重复项的数据库中，如果重复，则跳过它：
$content = file($selectfile1);
$posted_content = array();
list($rownum, $row) = each($content);
$posted_content[0] = explode(",", $row);
array_push($posted_content[0], "ID");
$count = 0;
// iterate each row (1 post)
while (list($rownum, $row) = each($content))
{
$count++;
$cols = "orderid, created_at, updated_at, notification_type, radius, available, expiration, ";
$vals = "";
$cols2 = "equipment_id";
$vals2 = "";
....{parsing data)...
}
我想写一个脚本，检查记录是否重复，如果没有输入。
$sql25 = "SELECT * FROM notifications WHERE origin =" . $origin_id . " user_id =12039";
$rs25 = $conn->Execute($sql25);
if($rs25->RecordCount() == 1 || $rs25->RecordCount() >= 1)
{
here is where i need a command. Can you use? next()
--------------------------------------------------
}
else
{
Insert query
}
您正在查找continue语句。
来自文档：
在循环结构中使用
continue来跳过当前循环迭代的剩余部分，并在条件评估时继续执行，然后开始下一次迭代。
(请参见http://www.php.net/manual/en/control-structures.continue.php)
示例：
<?php
while ( ... ) {
if ($foo = 'bar') {
// skip to the next iteration
continue;
}
}
