Question

我正在尝试从CSV读取数据并将其写入新CSV，将数据拆分为多个文件，其中电子邮件地址（$ row [14]）在每个文件中都是唯一的。我正在阅读的CSV已经通过电子邮件地址订购了。这里的循环正常工作，除了正在创建的文件都只包含一行。如何修改此操作以将行写入仅包含唯一电子邮件地址的每个文件。

<?php
 $file = fopen("yahrzeit-4.csv","r");
 $x=1;

 while  ( $row = fgetcsv( $file, ";" ) ) { 

 if ($file) {
 if ($email = $row[14] == $email) {

    $filename = 'mailchimp'.$x.'.csv';  

    $fpR = fopen($filename, 'w');   

    $dataR = array( $row[2], 
                $row[3], 
                $row[14], 
                $row[6] . ' ' . $row[7] . ' ' . $row[8], 
                $row[11] . ' ' . $row[10] . ', ' . $row[12], 
                jdtogregorian ( jewishtojd($Hebmonth, $row[6], 5774 ))
                );

    $email = $row[14];  $x++;   

}
    else { 

    $x=1;

    $fp = fopen('mailchimp.csv', 'w');  

    $data = array ( $row[2], 
                $row[3], 
                $row[14], 
                $row[6] . ' ' . $row[7] . ' ' . $row[8], 
                $row[11] . ' ' . $row[10] . ', ' . $row[12], 
                jdtogregorian ( jewishtojd($Hebmonth, $row[6], 5774 ))
              );

    }

    $email = $row[14];

}
fputcsv($fpR, $dataR);      
fputcsv($fp, $data);

}       

fclose($fp);
fclose($fpR);

?>

如果我理解正确，您似乎正在尝试创建包含其他CSV文件中记录的CSV文件。例外情况是，如果您发现重复的电子邮件地址，您希望这些地址为每个副本进入不同的文件，只要地址在每个文件中都是唯一的，就可以保留尽可能少的文件吗？

我显然没有检查过这个，因为我没有你的数据，但这应该有希望做你以后做的事情，把非唯一的电子邮件地址分成下一个可用的文件（对于那个地址））。

<?php
    $file = fopen("yahrzeit-4.csv","r");
    $addresses = array(); //This will hold counters for each address
    $fp = fopen('mailchimp.csv', 'w'); //This is the first list
    $fp2 = array(); //This will hold handles for each subsequent csv, 1 for each non-unique address (although it may hold more than one address unique to the file)

    if($file) {
        while  ( $row = fgetcsv( $file, ";" ) ) { //Read file
            if(isset($addresses[$row[14]])) { //Email has been found before at least once
                $targetfile = $addresses[$row[14]]; //Check the counter to find the next csv to write to for this particular address
                if(!isset($fp2[$targetfile])) { //Check if it has already been opened
                    $fp2[$targetfile] = fopen('mailchimp'.$targetfile.'.csv', 'w'); //If not open it and store it in the array of file handles for later use
                }

                $dataR = array( 
                    $row[2], 
                    $row[3], 
                    $row[14], 
                    $row[6] . ' ' . $row[7] . ' ' . $row[8], 
                    $row[11] . ' ' . $row[10] . ', ' . $row[12], 
                    jdtogregorian ( jewishtojd($Hebmonth, $row[6], 5774 ))
                );

                fputcsv($fp2[$targetfile], $dataR); //Write data to this file handle
                $addresses[$row[14]]++; //Increment counter for this email address so the next write will go into the next sequential file.

            } else { //This is the standard write if the address is not a duplicate
                $data = array (
                    $row[2], 
                    $row[3], 
                    $row[14], 
                    $row[6] . ' ' . $row[7] . ' ' . $row[8], 
                    $row[11] . ' ' . $row[10] . ', ' . $row[12], 
                    jdtogregorian ( jewishtojd($Hebmonth, $row[6], 5774 ))
                );

                fputcsv($fp, $data);
                $addresses[$row[14]] = 1;
            }
        }

        foreach($fp2 as $handle) { //Close all handles
            fclose($handle);
        }
        fclose($fp);
    }
