How can PHP developers effectively handle exclusion of specific lines or sections in a file, such as excluding the second line in the provided file format?

To exclude specific lines or sections in a file, such as excluding the second line in the provided file format, PHP developers can read the file line by line, skip over the line to be excluded, and then process the rest of the lines accordingly. This can be achieved by using functions like fopen(), fgets(), and fclose() to handle file operations in PHP. 

<?php
$filename = "example.txt";
$file = fopen($filename, "r");

if ($file) {
    $lineNumber = 1;
    while (($line = fgets($file)) !== false) {
        if ($lineNumber != 2) {
            // Process the line here
            echo $line;
        }
        $lineNumber++;
    }

    fclose($file);
} else {
    echo "Error opening file.";
}
?>
