PHP - How to count lines of code in an application [duplicate]

问题

I need to count the number of lines of code within my application (in PHP, not command line), and since the snippets on the web didn't help too much, I've decided to ask here. Thanks for any reply!

EDIT

Actually, I would need the whole snippet for scanning and counting lines within a given folder. I'm using this method in CakePHP, so I'd appreciate seamless integration.

回答1:

To do it over a directory, I'd use an iterator.

function countLines($path, $extensions = array('php')) {
    $it = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($path)
    );
    $files = array();
    foreach ($it as $file) {
        if ($file->isDir() || $file->isDot()) {
            continue;
        }
        $parts = explode('.', $file->getFilename());
        $extension = end($parts);
        if (in_array($extension, $extensions)) {
            $files[$file->getPathname()] = count(file($file->getPathname()));
        }
    }
    return $files;
}

That will return an array with each file as the key and the number of lines as the value. Then, if you want only a total, just do array_sum(countLines($path));...

You can use the file function to read the file and then count:

$c = count(file('filename.php'));

Using ircmaxell's code, I made a simple class out of it, it works great for me now

<?php
class Line_Counter
{
    private $filepath;
    private $files = array();

    public function __construct($filepath)
    {
        $this->filepath = $filepath;
    }

    public function countLines($extensions = array('php'))
    {
        $it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($this->filepath));
        foreach ($it as $file)
        {
           // if ($file->isDir() || $file->isDot())
           if ($file->isDir() )
            {
                continue;
            }
            $parts = explode('.', $file->getFilename());
            $extension = end($parts);
            if (in_array($extension, $extensions))
            {
                $files[$file->getPathname()] = count(file($file->getPathname()));
            }
        }
        return $files;
    }

    public function showLines()
    {
        echo '<pre>';
        print_r($this->countLines());
        echo '</pre>';
    }

    public function totalLines()
    {
        return array_sum($this->countLines());
    }

}

// Get all files with line count for each into an array
$loc = new Line_Counter('E:\Server\htdocs\myframework');
$loc->showLines();

echo '<br><br> Total Lines of code: ';
echo $loc->totalLines();

?>

$fp = "file.php";
$lines = file($fp);
echo count($lines);

回答5:

PHP Classes has a nice class for counting lines for php files in a directory:

http://www.phpclasses.org/package/1091-PHP-Calculates-the-total-lines-of-code-in-a-directory.html

You can specify the file types you want to check at the top of the class.

a little dirty, but you can also use system / exec / passthru wc -l *
