Are you using fgetcsv? If so it would be a simple matter of looping though the resulting array.

The general principal would be as follows

  1. Read the file with [fphp]file_get_contents[/fphp]
  2. Get the separate lines in an array using [fphp]explode[/fphp] by "
    ", let’s call this $lines
  3. For each of those lines
    3a) [fphp]explode[/fphp] the line on "\ "
    3b) Check if the third element of the result of 3a equals $pname
    3c) If it does, remove the element from $lines
  4. [fphp]implode[/fphp] the array $lines with "
    "
  5. Write the data back to the file using [fphp]file_put_contents[/fphp]
