Problem:

You did a svn checkout on this nice project but now you don’t want that .svn folders all over the place, after all you won’t be commiting it. Suddenly you find out that there’s thousands of folders with thousands of files.

Solution:

I wrote this little php cli script to fix this:

<?php

// (c) z3n - R1V1@101203 - www.overflow.biz - rodrigo.orph@gmail.com

function _o($msg) {
	echo "\r" . substr($msg,0, 79) . str_repeat(" ", 79 - strlen($msg));
}

function rddir($dir) { /* v2.17 */
	global $tfile,$tdir;

	if (is_dir($dir)) {
		if ($dh = opendir($dir)) {
			while (($file = readdir($dh)) !== false) {
				if ($file != "." && $file != "..") {
					if (is_dir($dir . $file))
						$tdir[] = $dir . $file;
					else
						$tfile[] = $file;
				}
			}
			closedir($dh);
		}
	}
}

if (!isset($argv[1]))
	die("Usage: " . $_SERVER['PHP_SELF'] . " <path/to/svn_root/>");

// browse dirs searching for .svn

for (
	$tdir = array($argv[1]),
	$tfile = array(),
	$svn = array(),
	$i = 0;$i < count($tdir);$i++)
{
	rddir($tdir[$i]);
	_o("Reading: ".$tdir[$i]." ...");

	foreach ($tfile as $entry) {
		if ($entry != "." && $entry != "..") {
			$fn = $tdir[$i] . (PHP_OS == "WINNT" ? "\\" : "/") . $entry;
			if ($entry == ".svn" && !in_array($fn, $svn))
				$svn[] = $fn;

			if (is_dir($fn) && $entry != ".svn")
				$tdir[] = $fn;
		}
	}

	$tfile = array();
}

_o("Found: " . count($svn) . " .svn folders, collecting files...");

$files = array();
$dirs = array();
$t = 0;

// collect files from .svn folders

foreach ($svn as $dir) {
	for ($tdir = array($dir), $tfile = array(),$i = 0;$i < count($tdir);$i++) {
		rddir($tdir[$i]);
		_o("[" . $t . "] - Collecting: ". $tdir[$i] ."...");

		foreach ($tfile as $entry) {
			if ($entry != "." && $entry != "..") {
				$fn = $tdir[$i] . (PHP_OS == "WINNT" ? "\\" : "/") . $entry;
				$t++;

				if (is_dir($fn)) {
					$tdir[] = $fn;
					$dirs[] = $fn;
				} else {
					$files[] = $fn;
				}
			}
		}
	}
}

$i = count($files) + count($dirs) + count($svn);

// delete files

foreach ($files as $file) {
	_o("[" . $i . "] Deleting Files: " . $file);
	unlink($file);
	$i--;
}

// delete subfolders

rsort($dirs);

foreach ($dirs as $dir) {
	_o("[" . $i . "] Deleting Dir: " . $dir);
	rmdir($dir);
	$i--;
}

// delete root .svn folders

foreach ($svn as $dir) {
	_o("[" . $i . "] Deleting Roots: " . $dir);
	rmdir($dir);
	$i--;
}

echo "\nDone!";

?>

Problem:

How to display detailed information about each table on a database?

Solution:

show table status;

Source:

MySQL

Problem:

I had a bunch of files but i didn’t knew which ones were doubles and which ones were unique, they had different names and belong to different subfolders.

Solution:

A PHP script that reads and do a md5 hash on every file then do a comparsion.

I keep forgeting about this so i decided to write a post.

Problem:

No decent css/js packers in php

Solution:

This CLI based script will compress the input files detecting their formats and placing on a defined folder, easying the automation of multiple files compression.

have fun!
