Get latest files from master branch and overwrite local files

Peace be upon you,
Sometimes, I forgot to commit the local changes and after a few days when I opened the project, I getting lost of what I am doing, So I prefer to sync back my local files with current head from master branch and over write file locally then start coding back from fresh.

git fetch
git reset --hard origin/master
git clean -f -d

Using git fetch command will fetch and import commits from a remote repository into our local repo, then the git reset --hard origin/master will reset our index and working tree, any changes before this will be discarded.

Search inside file content using GrepWin with Windows


Well, Windows operating system allow us to search inside file content by activating it from advance search menu but I prefer using alternative tools which allow me to use regular expression (RegEx) for more precise result. For now, I using GrepWin.

You can downnload GrepWin binary and source code at SourceForge : http://sourceforge.net/projects/grepwin/. Just right click on you target folder and start digging and searching the content that you want to find.

Hide default databases from phpmyadmin

Peace be upon you,
My favorite database are MySQL and PhpMyAdmin are the database administration that I use very frequently. MySQL and PhpMyAdmin comes with default configuration database such information_schema etc. Thus database that I not interact directly, I just interact with my own database set for my web application. So why not, we just hide these database from PhpMyAdmin?

Just locate and open \phpMyAdmin\config.inc.php with your favorite text editor (I use SublimeText3) and add this regex code:
/* hide database from phpmyadmin */
$cfg['Servers'][$i]['hide_db'] = '^(information_schema|performance_schema|mysql|phpmyadmin|cdcol|foo|webauth)$';

Then reload / restart your apache and mysql, and see changes on http://localhost/phpmyadmin, check it out on the left side. Now, we just see our own created database only.

Alternative way:
Open and browse "PhpMyAdmin" > Click on "Setting" tab > Then click on "Feature" tab and paste this code within "Hide database" field
^(information_schema|performance_schema|mysql|phpmyadmin|cdcol|foo|webauth)$

Thus default database are just hide from PhpMyAdmin and If you are using tool such MySQL Workbench, NaviCat, HeidiSQL,RazorSQL software or else, thus database still there and available. Hope this tips are useful. That all for now. Wassalam...

<?php

Checking which local branch is tracking which remote branch in Git?

For all branches:
git branch -avv

For local branches only:
git branch -lvv

shows you all branches as well as the name of the upstream branch.

Change git remote from SSH to HTTPS

Peace be upon you.. My office has strict network rules which filtered by proxy on port 8080 and does not allow me to use SSH connection to fetch and pull on my git repository. I tried to use subversion a.k.a svn as alternative but I not familiar with the command and GUI tool such RapidSVN on linux are not very helpful. Then, I google-fu and found that git support HTTPS connection too! Wohaa..good!

Let's check our current remote repository URL:
$ git remote -v
Now change our remote's URL from SSH to HTTPS with the git remote set-url command:
$ git remote set-url origin https:[email protected]/wawang/sistem_repo.git
* I use Bitbucket as example above, means it depends on your git hosting provider
* Bitbucket URL format : https://<username>@bitbucket.org/<username>/<reponame>.git
* Github URL format : https://github.com/<username>/<reponame>.git

Now, verify the remote repository URL using the git remote -v command. Easy right? That all,Peace!

Laravel 5 - No supported encrypter found. The cipher and / or key length are invalid

Hey, I got an error msg said my laravel 5 installation went wrong :

We need to create a random of 32 char string as application key. Just run the command and get the access key:
$ php artisan key:generate

Copy that generated key and put it inside /config/app.php file, for example :
'key' => env('APP_KEY', 'ql9xRk2DuYTdl8QJrmjmRCfRx3kyCZC2'),

Dont forget to give write permission for /storage directory (chmod -R 755 are enough for that).

How to enable PHP debugging with XAMPP for Linux and XDebug

Peace be upon you.. I decide to learn debugging PHP web application using XAMPP for Linux and XDebug. This tutorial are based from XAMPP for Linux 5.6.11, but it suppose will be valid in future because I using xdebug that provided with the XAMPP and I just enable it.

Let's check our PHP installation with php --version command
$ php --version
PHP 5.6.11 (cli) (built: Aug 10 2015 20:47:04) 
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies
    with Xdebug v2.2.5, Copyright (c) 2002-2014, by Derick Rethans
* Note : If the output said about Xdebug version, it mean you PHP already debug enable and else are not enable yet.

The another way to check is to read from PHP info, just create a new file with code below and execute from our localhost:
<?php phpinfo() ?>
* Note : Find "xdebug" using ctrl+f and if you found this section it mean you PHP already debug enable and else are not enable yet.

Now, I assume our PHP does not enable Xdebug yet.. and we are going to enable it by edit /opt/lampp/etc/php.ini file
$ gksudo  gedit /opt/lampp/etc/php.ini
Add this line inside that file :
zend_extension = /opt/lampp/lib/php/extensions/no-debug-non-zts-20131226/xdebug.so
And now, restart the server and after that we can run / debug the PHP web application :
$ sudo /opt/lampp/xampp restart
So easy right? That all we need, Thanks.

Composer - /usr/bin/env: php: No such file or directory

Today, I setup LAMPP (XAMPP) and laravel PHP framework with Ubuntu 15.04 but when I want use composer, this problem occur :
$ sudo composer install
/usr/bin/env: php: No such file or directory
The solution is to symlink the PHP cli with the bin path:
$ sudo ln -s /opt/lampp/bin/php /usr/local/bin/php
Nice and well played :)
