Question

The test.php directory is the same as csv and text file. now i want to pass all the csv file name and all the text name to the following if condition. namely, replace one.csv with all the csv file name. replace one.txt with all the txt file name.

if (($handle = fopen("one.csv", "r")) !== FALSE && ($handle2 = fopen("one.txt", 'a')) !== FALSE) { ...}

the following is my code. after run the code,i found all the content in the text file are the same. it loops too many times. how to change the code?thank you.

    $files = glob("./*.csv");
    $files1 = glob("./*.txt");
    foreach($files as $filepath){
    foreach($files1 as $filepath1){


   $row = 1;
if (($handle = fopen("one.csv", "r")) !== FALSE && ($handle2 = fopen("one.txt", 'a')) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        if($row > 1) {
            $url = $data[8];
            foreach($result[0] as $url){
                fwrite($handle2, $url."\r\n");
            }

        }
        $row++;
    }
    fclose($handle);
    fclose($handle2);
}

    }
    }

The txt file is empty. now, i want to read the csv file and extract some content of it then put them into the text file. thank you

You don’t need to glob .txt files, just glob csv, and replace the extension .csv by .txt

$csv = glob('./*.csv');
foreach($csv as $file) {
   $txt = preg_replace('#\.csv$#', '.txt', $file);
   if (($handle = fopen($file, "r")) !== FALSE && ($handle2 = fopen($txt, 'a')) !== FALSE) {
    //your code...
    }
}
