PHP5系からPHP7に移行した。(Homebrew

PHP7 casualTalks#1の始まる前にざっとやって、  
LT一本目まで入ってしまったけど取り合えず入れれたのでやったこと。
(PHP7の勉強会出てるのにPHP7入れてないってどういうこと？と思ったので)

## 概要

* Homebrew
* Yosemite
* 以前まではphp5.5を入れてたっぽい？初心者のころに買ったmacだからよくわからぬ

## 入れようとする

```
$ brew update
$ brew install homebrew/php/php70

エラー。

調べたらuntapしろと。

```
brew untap josegonzalez/php
brew tap --repair
brew update
```

```
 brew install homebrew/php/php70
==> Installing php70 from homebrew/php
Error: Cannot install homebrew/php/php70 because conflicting formulae are installed.

  php55: because different php versions install the same binaries.

Please `brew unlink php55` before continuing.

Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.
```

またもやエラー。
php55を外す

```
$ brew unlink php55
Unlinking /usr/local/Cellar/php55/5.5.22... Error: Permission denied - /usr/local/lib/php/.channels
```

うっ。エラー出た。。。
今回はunlinkだったからsudoで対応

```
$ sudo brew unlink php55
```

おし、行けた。

インストールしよう。

```
$ brew install homebrew/php/php70
```

This formula is keg-only, which means it was not symlinked into /usr/local.

OS X provides the BSD gettext library and some software gets confused if both are in the library path.

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/gettext/lib

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php7_module    /usr/local/opt/php70/libexec/apache2/libphp7.so

    <FilesMatch .php$>
        SetHandler application/x-httpd-php
    </FilesMatch>

Finally, check DirectoryIndex includes index.php
    DirectoryIndex index.php index.html

The php.ini file can be found in:
    /usr/local/etc/php/7.0/php.ini

✩✩✩✩ Extensions ✩✩✩✩

If you are having issues with custom extension compiling, ensure that
you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:

      PATH="/usr/local/bin:$PATH"

PHP70 Extensions will always be compiled against this PHP. Please install them
using --without-homebrew-php to enable compiling against system PHP.

✩✩✩✩ PHP CLI ✩✩✩✩

If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc,
~/.zshrc, ~/.profile or your shell's equivalent configuration file:

      export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH"

✩✩✩✩ FPM ✩✩✩✩

To launch php-fpm on startup:
    mkdir -p ~/Library/LaunchAgents
    cp /usr/local/opt/php70/homebrew.mxcl.php70.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist

The control script is located at /usr/local/opt/php70/sbin/php70-fpm

OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:

  PATH="/usr/local/sbin:$PATH"

You may also need to edit the plist to use the correct "UserName".

Please note that the plist was called 'homebrew-php.josegonzalez.php70.plist' in old versions
of this formula.

To have launchd start homebrew/php/php70 at login:
  ln -sfv /usr/local/opt/php70/*.plist ~/Library/LaunchAgents
Then to load homebrew/php/php70 now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php70.plist

出来たっぽいぞー？

あとはbashrcにパスを通したほうが良い模様なので通す。



```
export PATH="$(brew --prefix homebrew/php/php70)/bin:$PATH"
```

これで良さそうだ。何か問題が起きたら再度考える。
