跳出内循环，继续外循环答案

【问题标题】：Getting out of the inner loop and contnuing with the outer loop跳出内循环，继续外循环

【问题描述】：

我有一个 while 循环，它从 csv 获取数据。在 while 循环内部有一个条件（如果条件），如果条件为真，foreach 循环将在我们想一次将一行插入数据库的地方执行。对于 csv 的每一行，这应该继续。如果我在 csv 中有 10 行，它应该在数据库中插入所有 10 行。但是 mycode 将第一行插入 10 次。

$handle = fopen($_FILES['upcsv']['tmp_name'], "r");
$count = count(file($_FILES['upcsv']['tmp_name']));
fgetcsv($handle, 1000, ",");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) 
{
   $clt = mysql_query("select MCLNTLKNOFLG,MCLNTDKTRNGFRM,MCLNTDKTRNGTO from mclientmst where MCLNTCD ='".$data[1]."'");
   if(mysql_num_rows($clt)>0)
   {    
      $clts = mysql_fetch_array($clt);
      if($clts['MCLNTLKNOFLG']==1)
      {
         $i=1 ;
         foreach(range ($clts['MCLNTDKTRNGFRM'], $clts['MCLNTDKTRNGTO']) as $num)
         {
           $dkt = mysql_query("select XCMPCD from  xdockethdr where XDKTNO ='$num'");
           $ndkt = mysql_query("select XCMPCD from  xtempdockethdr where XDKTNO ='$num'");
           if(mysql_num_rows($dkt)==0 && mysql_num_rows($ndkt)==0)
           {
              $date = explode('/',$data[3]);
              $dt = $date[2].'-'.$date[1].'-'.$date[0];
              $dktid = mysql_query("select MAX(XDKTID) as maxid from xtempdockethdr");
              $maxid = mysql_fetch_array($dktid);
              $max = $maxid['maxid'] +1;
              $query = mysql_query("insert into xtempdockethdr (XCMPCD,XCLNTCD,XDKTNO,XCNSGCD,XDKTPUDATE,XDKTPUTIME,XDKTNOPKGS,XDKTMODLV,XDKTHTOCONCD,XDKTDCTVAL,XDKTDIMWT,XDKTACTWT,XUNIQUEID,XDKTID) VALUES ('".$data[0]."','".$data[1]."','".$num."','".$data[2]."','".$dt."','".$data[4]."','".$data[5]."','".$data[6]."','".$data[7]."','".$data[8]."','".$data[9]."','".$data[10]."','".$data[11]."','".$max."')");   
              $i++; 
           }
         }
      }
   }    
}
fclose($handle);

【解决方案1】：

你需要在你的代码后面设置一个break;。它将关闭第一个循环（foreach）并关闭。

在 sql 插入后添加 continue 2;。这将结束此循环并进入 while 循环的开头并继续工作。

$handle = fopen($_FILES['upcsv']['tmp_name'], "r");
$count = count(file($_FILES['upcsv']['tmp_name']));
fgetcsv($handle, 1000, ",");
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) // **#1 point**
{
   $clt = mysql_query("select MCLNTLKNOFLG,MCLNTDKTRNGFRM,MCLNTDKTRNGTO from mclientmst where MCLNTCD ='".$data[1]."'");
   if(mysql_num_rows($clt)>0)
   {    
      $clts = mysql_fetch_array($clt);
      if($clts['MCLNTLKNOFLG']==1)
      {
         $i=1 ;
         foreach(range ($clts['MCLNTDKTRNGFRM'], $clts['MCLNTDKTRNGTO']) as $num)
         {
           $dkt = mysql_query("select XCMPCD from  xdockethdr where XDKTNO ='$num'");
           $ndkt = mysql_query("select XCMPCD from  xtempdockethdr where XDKTNO ='$num'");
           if(mysql_num_rows($dkt)==0 && mysql_num_rows($ndkt)==0)
           {
              $date = explode('/',$data[3]);
              $dt = $date[2].'-'.$date[1].'-'.$date[0];
              $dktid = mysql_query("select MAX(XDKTID) as maxid from xtempdockethdr");
              $maxid = mysql_fetch_array($dktid);
              $max = $maxid['maxid'] +1;
              $query = mysql_query("insert into xtempdockethdr (XCMPCD,XCLNTCD,XDKTNO,XCNSGCD,XDKTPUDATE,XDKTPUTIME,XDKTNOPKGS,XDKTMODLV,XDKTHTOCONCD,XDKTDCTVAL,XDKTDIMWT,XDKTACTWT,XUNIQUEID,XDKTID) VALUES ('".$data[0]."','".$data[1]."','".$num."','".$data[2]."','".$dt."','".$data[4]."','".$data[5]."','".$data[6]."','".$data[7]."','".$data[8]."','".$data[9]."','".$data[10]."','".$data[11]."','".$max."')");   
              $i++; 
              // continue 2; // Goes to #1
              // break; // Goes to #2
           }
         } // #2 point
         var_dump(__LINE__); // This will executed if you place break operator
      }
   }    
}
fclose($handle);
header('Location:upload_docketentry.php');
