How to add lines to a CSV file without overwriting it












4















$file = fopen("contacts.csv","w");
foreach(array_unique($matches[0]) as $email) {
fputcsv($file,explode(',',$email));
}
fclose($file);


The above code generates a CSV file. How can I update the CSV from the last recorded line without overwriting from the beginning?

          Change "w" to "a" in the fopen. It changes "write" into "append".



          "append" opens the file and writes at the end of the file, not from the beginning like "write".



          i.e. change this line



          $file = fopen("contacts.csv","w");



          to



          $file = fopen("contacts.csv","a");
