Często zachodzi potrzeba przeliczenia danego pliku pod względem liczby linni tekstu, które w nim występują. Aby policzyć liczbę linii w pliku zastosuj następujące rozwiązanie:

Przykład:

Kod: php

<?
  $plik = ‘plik.txt’;
    $liczba_linii = count(file($plik));
  echo $liczba_linii;
?>

Do zmiennej $plik przypisuję wartość "plik.txt". Pobieram wskazany plik funkcją file(). Zawartość pliku w formie tablicy zostaje policzona funkcją count(), a następnie przypisana do zmiennej $liczba_linii. Na koniec wyświetlam na ekran zmienną $liczba_linii.
