What is the best approach to iterate through a file in PHP and count specific lines that meet a condition?

To iterate through a file in PHP and count specific lines that meet a condition, you can open the file, read it line by line, check if each line meets the condition, and increment a counter accordingly. Once you have gone through all the lines in the file, you will have the count of lines that meet the condition. 

$file = fopen("file.txt", "r");
$count = 0;

while(!feof($file)) {
    $line = fgets($file);
    // Check if the line meets the condition
    if (/* condition */) {
        $count++;
    }
}

fclose($file);

echo "Number of lines that meet the condition: " . $count;
