V8 Javascript Engine for PHP on Mac

Log — Tags: github, javascript, PHP — Posted by Starck on April 8, 2013

This is a PHP extension embeds the Google V8 Javascript Engine.

Installation

brew install v8
git clone https://github.com/preillyme/v8js
cd v8js
phpize
# MacOS
# ./configure CXXFLAGS="-Wno-c++11-narrowing"
./configure
make; sudo make install

git clone https://github.com/preillyme/v8js

cd v8js

phpize

# MacOS

# ./configure CXXFLAGS="-Wno-c++11-narrowing"

./configure

make; sudo make install

Usage

check samples and tests folder

Problems

如果你經由 PECL 安裝 v8js:

sudo pecl install v8js

你可能會遇到一些編譯上的錯誤, 造成這個問題的原因是因為在 PECL 上的版本 0.1.3 使用了一個已經被最新版 V8 engine 所廢除的函式, 如果想要使用這個版本的話必須要使用 V8 3.15.11 的版本, 降版的方式如下:

brew install v8-3.15.11

如果之後想要切換回新版:

# 查看目前安裝哪些版本
brew info v8
# 切換版本
brew switch 3.17.10

Log — Tags: Laravel, PHP — Posted by Starck on March 31, 2013

Migrations

Migrations Installation

migrate:install : it will crate a migrations table for record any changes of database.

$ php artisan migrate:install

1	$ php artisan migrate:install

Making a new migration record

migrate:make (create|remove)_tablename_table

$ php artisan migrate:make create_authors_table

1	$ php artisan migrate:make create_authors_table

The --table and --create options may also be used to indicate the name of the table, and whether the migration will be creating a new table:

$ php artisan migrate:make create_authors_table --table=authors --create

// up() 
Schema::create('authors', function($table){ 
  $table->increments('id'); 
  $table->string('name'); 
  $table->text('bio'); 
  $table->timestamp(); 
});

// down() 
Schema::drop('authors');

Schema::drop('authors');

Running All Outstanding Migrations

$ php artisan migrate

To seed your database, you may use the db:seed command on the Artisan CLI:

$ php artisan db:seed

Rollback all migrations and run them all again

$ php artisan migrate:refresh --seed

Artisan

Check routes status: $ php artisan routes

Clear auto-load files: $ php artisan clear-compiled

Re-generate auto-load files: $ php artisan dump-autoload

Upgrading PHP on MacOS

Log — Tags: Apache, Brew, Mac, PHP — Posted by Starck on March 29, 2013

所需工具

使用 Brew 讓在 MacOS 安裝管理套件變得容易許多, 而 HomeBrew-PHP 則是讓你在 MacOS 上安裝 PHP 和管理 extensions 的 Brew 套件.

Brew

安裝 Brew:

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

如果之前已經安裝過 Brew, 依據習慣, 我會將 Brew 更新到最後的版本:

brew update

brew upgrade

Installation

Tap the homebrew/dupes repository into your brew installation:

brew tap homebrew/dupes

Tap the repository into your brew installation:

brew tap josegonzalez/homebrew-php

安裝參數說明

brew options php54

安裝 php 5.4

brew install php54

安裝時可能會出現的問題

jpeg8-d:

jpeg8-d is already installed, it's just not linked
    Could not symlink file: /usr/local/Cellar/jpeg/8d/bin/wrjpgcom
    Target /usr/local/bin/wrjpgcom already exists. You may need to delete it.
    To force the link and delete this file, do:
    brew link --overwrite formula_name

解法: brew link --overwrite jpeg

reference

Apache httpd.conf 設定

先檢查 /usr/local/Cellar/php54/ 下的 php 版本號是多少, 例如: 5.4.12

# /etc/apache2/httpd.conf
# Swapping from PHP53 to PHP54
# LoadModule php5_module    /usr/local/Cellar/php53/5.3.20/libexec/apache2/libphp5.so
LoadModule php5_module    /usr/local/Cellar/php54/5.4.12/libexec/apache2/libphp5.so

# /etc/apache2/httpd.conf

# Swapping from PHP53 to PHP54

# LoadModule php5_module /usr/local/Cellar/php53/5.3.20/libexec/apache2/libphp5.so

LoadModule php5_module /usr/local/Cellar/php54/5.4.12/libexec/apache2/libphp5.so

** Update 2013-08-07 **

在 Moutain Lion Server 下, 修改 php module 讀取路徑要到 /Library/Server/Web/Config/apache2/httpd_server_app.conf

** Update 2013-10-26 **

After updating Mavericks Server, please also upgrade to the latest Xcode and make sure you re-install Command-line Tools: xcode-select --install

Edit /Library/Server/Web/Config/apache2/httpd_server_app.conf:

# LoadModule php5_module libexec/apache2/libphp5.so
LoadModule php5_module /usr/local/opt/php54/libexec/apache2/libphp5.so

1 2	# LoadModule php5_module libexec/apache2/libphp5.so LoadModule php5_module /usr/local/opt/php54/libexec/apache2/libphp5.so

如果使用 FPM, 請在 Terminal 下達:

cp /usr/local/Cellar/php54/5.4.12/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/
launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist
launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist

cp /usr/local/Cellar/php54/5.4.12/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/

launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist

launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist

Command-line

If you would like to swap the PHP you use on the command line, you should update the $PATH variable in either your .bashrc or .bash_profile:

# Swapping from PHP53 to PHP54
# export PATH="$(brew --prefix josegonzalez/php/php53)/bin:$PATH"
export PATH="$(brew --prefix josegonzalez/php/php54)/bin:$PATH"

# Swapping from PHP53 to PHP54

# export PATH="$(brew --prefix josegonzalez/php/php53)/bin:$PATH"

export PATH="$(brew --prefix josegonzalez/php/php54)/bin:$PATH"

[MacOS] mysql.sock error

Log — Tags: Mac, PHP — Posted by Starck on March 28, 2013

今天在使用 Terminal 連線到本機 MySQL 時發生錯誤:

ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

因為平常使用 phpMyAdmin 都是正常的, 所以不確定這個情況是什麼時候開始和什麼原因造成的. 查看 /etc/my.cnf, 確認 mysql.sock 是設在 /var/mysql/mysql.sock(不知道為什麼用 mysql 指令時它會跑去透過 /tmp/mysql.sock) , 沒時間處理這個問題, 所以先用 symbolic link 的方式解決.

$ ln -s /var/mysql/mysql.sock /tmp/mysql.sock

Laravel 4 Tutorial Part 1 – Installation and Configuration

Coding — Tags: Laravel, PHP — Posted by Starck on March 26, 2013

Laravel

根據官網的說法:

Laravel is a clean and classy framework for PHP web development. Freeing you from spaghetti code, Laravel helps you create wonderful applications using simple, expressive syntax.

Development should be a creative experience that you enjoy, not something that is painful. Enjoy the fresh air.

–

大略看了文件後，覺得跟 Ruby on Rails 的概念很接近，以下幾點特色很吸引我:

Artisan : command-line 的操作方式, 支持擴充指令
Autoloading : 採用 Composer 的 autoload 機制, 不用再一直忘了 require 了
Blade Template Engine : 簡單好用的模版引擎
Migration / Seeding : 資料庫的版本管理
Query Builder : 幾乎所有的 MVC Framework 都會有這樣的 SQL 操作類
Eloquent ORM / Auth : 直接就有 ORM 可以用! 並有一個簡單的 Authentication 機制
Dependency Injection
IoC Container

安裝

Get Laravel from Github

$ mkdir {project_folder}
$ cd {project_folder}
$ get clone git://github.com/laravel/laravel.git
$ git checkout develop

–

Laravel 從 4 開始就不再用舊有的 Bundle, 而採用 Composer 來作 packages 的管理與安裝.

下載 Composer

$ curl -sS https://getcomposer.org/installer | php

付予 Composer 可執行的權限

這時專案資料夾會有一個 composer.phar 的文件, 我習慣把它命名為 composer 並付予可執行的權限:

$ chmod +x ./composer.phar
$ mv composer.phar composer

–

安裝 Composer

$ composer install

安裝 Laravel 所需的 packages

$ composer update

到這裡如果都沒有發生任何錯誤, Laravel 4 就算安裝完成了.

–

開發工具

我個人偏好用 SublimeText 2 or Vim 來作為我開發的 IDE, 而基於 Laravel 我比較建議用 SublimeText, 因為有一個方便的 LaravelGenerator, 使用這個 Plugin 前需要安裝 Laravel-4-Generators.

安裝 LaravelGenerator SublimeText Plugin

在 SublimeText 中:

Command + Shift + p

出現提示後然後輸入:

install 選擇 Package Control: Install Package

接著輸入: LaravelGenerator 選擇我們要安裝的 Plugin

這樣我們就已經把 LaravelGenerator Plugin 裝進 SublimeText 了

–

安裝 Laravel-4-Generators Package

開啟專案根目錄下的 composer.json, 在 require 設定加入 "way/generators": "dev-master"

"require": {
    "laravel/framework": "4.0.*",
    "way/generators": "dev-master"
},

1

2

3

4

"require": {

"laravel/framework": "4.0.*",

"way/generators": "dev-master"

},

更新並下載所需的 packages

$ composer update

加入 Laravel 的 ServiceProvider

開啟 app/config/app.php

在 providers 中加上 'Way\Generators\GeneratorsServiceProvider', 讓 artisan 運行時自動載入所需的類別

檢查 Laravel-4-Generators 是否安裝成功

$ php artisan

如果出現訊息有包含以下資訊就代表 package 安裝成功了:

generate
  generate:migration   Generate a new migration.
  generate:model       Generate an Eloquent model.
  generate:resource    Generate a new resource.
  generate:seed        Generate a DB seed class.
  generate:test        Generate a PHPUnit Test.
  generate:view        Generate a new view

可以參考 Pro Workflow in Laravel and Sublime Text 中的影片教學.

設定

儲存區目錄權限設定

將 app/storage 這個資料夾裡所有文件和目錄都設為可寫入的權限:

$ chmod -R 777 ./app/storage/

在 Server 上因為我習慣上會把網站文件的群組設為 apache (CentOS) or www-data (Ubuntu), 再付予群組的寫入權限.

$ chown -R user:group ./app/storage
$ chmod -R g+x ./app/storage

環境設定

Laravel 的設定檔都統一放置在 app/config/ 裡, 而 Laravel 可以依據 HTTP host 來決定讀取不同的設定檔, 例如測試主機和正式主機的資料庫設定可能會有所不同.

設定檔預設就是用在 production 環境, 如果有特定的設定需要在 localhost 本機環境下作變動, 只要在 app/config/ 建立一個 local 資料夾, 並把設定檔放置其中即可, 例如 database.php.

example:

app/config/ - 放置正式上線的 production 設定
app/config/local/ - 放置本機環境的設定
app/config/testing/ - Unit Testing 用的設定

環境的定義請見 /bootstrap/start.php 中

/*
|--------------------------------------------------------------------------
| Detect The Application Environment
|--------------------------------------------------------------------------
|
| Laravel takes a dead simple approach to your application environments
| so you can just specify a machine name or HTTP host that matches a
| given environment, then we will automatically detect it for you.
|
*/

$env = $app->detectEnvironment(array(

    'local' => array('your-machine-name'),

));

|

*/

$env = $app->detectEnvironment(array(

'local' => array('your-machine-name'),

));

Laravel 已經事先幫你定義好 local 的環境定義, 所以你只需把 your-machine-name 置換成你的電腦名稱或是 localhost.

Encryption Key

在編寫任何程式之前, 請先修改 app/config/app.php 的 key (Encryption Key).

你也可以用 artisan 自動產生一組隨機文字的 key, 在這之前需要先將原本的 key 刪除:

/*
|--------------------------------------------------------------------------
| Encryption Key
|--------------------------------------------------------------------------
|
| This key is used by the Illuminate encrypter service and should be set
| to a random, long string, otherwise these encrypted values will not
| be safe. Make sure to change it before deploying any application!
|
*/

    'key' => '',

| to a random, long string, otherwise these encrypted values will not

| be safe. Make sure to change it before deploying any application!

|

*/

'key' => '',

接著在 Terminal 下達:

$ php artisan key:generate
