Line Count

File text can be counted and summarized without exposing a file handle.

line_count.php

<?php
$extra = ;
$file = "php_lines_file.txt";

file_put_contents($file, "one\ntwo\n" . $extra . "\n");
$content = trim(file_get_contents($file));
$lines = substr_count($content, "\n") + 1;
unlink($file);

echo "extra=" . $extra . "\n";
echo "lines=" . $lines . "\n";

<?php

$file = "php_lines_file.txt";

file_put_contents($file, "one\ntwo\n" . $extra . "\n");
$content = trim(file_get_contents($file));
