What are some best practices for counting line breaks in a text file using PHP?

When counting line breaks in a text file using PHP, one approach is to read the file line by line and increment a counter for each line read. This can be achieved by using the `fgets()` function to read each line and a counter variable to keep track of the number of lines. Another approach is to use the `file()` function to read the entire file into an array and then count the number of elements in the array, which corresponds to the number of lines in the file. 

// Method 1: Reading file line by line
$filename = 'example.txt';
$lineCount = 0;

$handle = fopen($filename, 'r');
if ($handle) {
    while (($line = fgets($handle)) !== false) {
        $lineCount++;
    }
    fclose($handle);
}

echo "Number of lines in $filename: $lineCount";

// Method 2: Using file() function
$filename = 'example.txt';
$lines = file($filename, FILE_IGNORE_NEW_LINES);
$lineCount = count($lines);

echo "Number of lines in $filename: $lineCount";
