Question

I’d like to,

1. Check the word count for a folder full of text files.
2. Output a list of the files arranged by word count in the format – FILENAME is WORDCOUNT

I know str_word_count is used to get individual wordcounts for files but I’m not sure how to rearrange the output.

Thanks in advance.

Answer 1

Adapted from here.

<?php
    $files = array();
    $it = new DirectoryIterator("/tmp");
    $it->rewind();
    while ($it->valid()) { 
        $count = str_word_count(file_get_contents($it->getFilename()));
        $files[sprintf("%010d", $count) . $it->getFilename()] =
            array($count, $it->getFilename()); 
        $it->next();
    }

    ksort($files);
    foreach ($files as $tup) {
        echo sprintf("%s is %d\n", $tup[1], $tup[0]);
    }

EDIT It would be more elegant to have $file‘s key be the file name and $file‘s value be the word count and then sort by value.
