Php 将动态生成的字符串追加到CSV行的末尾

所以我有两个CSV：InputCSV和OutputCSV

InputCSV.csv

name     col1     col2     col3     col4     col5
john     qOJY     OHXl     vIOH     Tdnm     Z7OH
greg     YRc1     hyFB     pW8m     5LSE     Yo4r
saly     Dy4o     51Ui     tuKI     02VQ     RVgB

name     url
john     site.com/JcRIeyFCEl.mp4
greg     site.com/TTwF4Cue2B.mp4
saly     site.com/ouroANTtAC.mp4

name     url                         thumbfile
john     site.com/JcRIeyFCEl.mp4     site.com/snTflxaqNI.jpg
greg     site.com/TTwF4Cue2B.mp4     site.com/ELrg6vwKEr.jpg
saly     site.com/ouroANTtAC.mp4     site.com/xTjfqCEoIZ.jpg

OutputCSV.csv

name     col1     col2     col3     col4     col5
john     qOJY     OHXl     vIOH     Tdnm     Z7OH
greg     YRc1     hyFB     pW8m     5LSE     Yo4r
saly     Dy4o     51Ui     tuKI     02VQ     RVgB

name     url
john     site.com/JcRIeyFCEl.mp4
greg     site.com/TTwF4Cue2B.mp4
saly     site.com/ouroANTtAC.mp4

name     url                         thumbfile
john     site.com/JcRIeyFCEl.mp4     site.com/snTflxaqNI.jpg
greg     site.com/TTwF4Cue2B.mp4     site.com/ELrg6vwKEr.jpg
saly     site.com/ouroANTtAC.mp4     site.com/xTjfqCEoIZ.jpg

所以在processor.php中，我有

    if (($csvFile = fopen("InputCSV.csv", "r")) !== false && ($resultCsv = fopen("OutputCSV.csv", 'w')) !== false) {
        while (($data = fgetcsv($csvFile)) !== false) {
            // do stuff to generate $thumbfile
            // this bit needs to use parts of $data like $data[3], $data[5] to generate $thumbfile
            // which in the end should look like $thumbfile = 'site.com/rAndOmsTRing.jpg';
        }
    $outputData = fgetcsv($resultCsv);
    $outputData[] .= $thumbfile_url; //Append to end of line. is this what I'm doing wrong? 
    fputcsv($resultCsv, $outputData);

我需要做的是在OutputCSV.csv中添加一个新列，并在每行/每行的末尾追加$thumbfile。目前，它所做的是删除现有的两列，并仅将$thumbfile作为一列写入

OutputCSV.csv在运行此脚本后需要如下所示： OutputCSV.csv

name     col1     col2     col3     col4     col5
john     qOJY     OHXl     vIOH     Tdnm     Z7OH
greg     YRc1     hyFB     pW8m     5LSE     Yo4r
saly     Dy4o     51Ui     tuKI     02VQ     RVgB

name     url
john     site.com/JcRIeyFCEl.mp4
greg     site.com/TTwF4Cue2B.mp4
saly     site.com/ouroANTtAC.mp4

name     url                         thumbfile
john     site.com/JcRIeyFCEl.mp4     site.com/snTflxaqNI.jpg
greg     site.com/TTwF4Cue2B.mp4     site.com/ELrg6vwKEr.jpg
saly     site.com/ouroANTtAC.mp4     site.com/xTjfqCEoIZ.jpg

注意：我使用的实际csv没有标题。我把它们放在那里只是为了方便阅读。

要制作您需要的内容，您需要将OutputCSV.csv的数据保存在数组中，然后在同一数组中添加$thumbfile

这里是一个示例，我使用您的csv文件，文件之间用、

    if (($csvFile = fopen("InputCSV.csv", "r")) !== false && ($resultCsv = fopen("OutputCSV.csv", 'r')) !== false) {
        while (($data = fgetcsv($csvFile,4096,",")) !== false) {
        // do stuff to generate $thumbfile
        $thumbfile[]=$data[3].$data[5].".jpg";
            }
        $x=0;
        while (($dataoutput = fgetcsv($resultCsv,4096,",")) !== false) {
            $dataotputcsv[$x]=$dataoutput;   //here is [0]=> "john" [1]=> "site.com/JcRIeyFCEl.mp4"
            array_push($dataotputcsv[$x], $thumbfile[$x]);  //here i add the $thumbfile
      //and now is [0]=> "john" [1]=> "site.com/JcRIeyFCEl.mp4" [2]=> "vIOHZ7OH.jpg"
        $x++;
        }
        $file = fopen("OutputCSV.csv", 'w'); 
        foreach($dataotputcsv as $string) {
            fputcsv($file, $string);  //save all lines to file
        }

    }
