# PHP 7.3



### Changer de version de PHP:

```bash
$ brew unlink php@7.3 && brew link --force --overwrite php@5.6
```

On installe un petit utilitaire [PHP Switcher Script](https://gist.github.com/rhukster/f4c04f1bf59e0b74e335ee5d186a98e2)

```bash
$ curl -L https://gist.githubusercontent.com/rhukster/f4c04f1bf59e0b74e335ee5d186a98e2/raw > /usr/local/bin/sphp
$ chmod +x /usr/local/bin/sphp

https://gist.github.com/rhukster/f4c04f1bf59e0b74e335ee5d186a98e2/raw/b51e5f561dc6492249ac167813b9b40dcdd72bd0/sphp.sh
```

Ensuite pour changer de version:

```bash
$ sphp 7.3
```

Par exemple, pour passer de 7.2.13. à 7.3.0_1:

```bash
$ sphp 7.3
Switching to php@7.3

### Extensions:

#### Liste des extensions (Homebrew):

```bash
$ brew search php73
```

#### Installer des extensions (avec [PECL](https://pecl.php.net)):

Requiert autoconf: `brew install autoconf`

```bash
  $ pecl uninstall -r xdebug
  
  $ pecl install xdebug
  $ pecl install yaml
  $ pecl install redis
  $ pecl install apcu
  $ pecl install memcached
  $ pecl install imagick
  
  # Pour une version spécifique:
  $ pecl install xdebug-2.7.0beta1
```

Pour les activer, créez un fichier de configuration dans  `/usr/local/etc/php/7.3/conf.d/`

```bash
bruno@silverbook:/usr/local/etc/php/7.3/conf.d$ l
total 32
drwxr-xr-x  6 bruno  admin  192  4 jan 19:32 .
drwxr-xr-x  9 bruno  admin  288  3 jan 19:34 ..
-rw-r--r--  1 bruno  admin   72  4 jan 16:09 ext-opcache.ini
-rw-r--r--  1 bruno  admin  172  4 jan 18:58 ext-xdebug.ini
-rw-r--r--  1 bruno  admin   81  4 jan 18:43 ext-yaml.ini
-rw-r--r--  1 bruno  admin   87 13 déc 07:12 fix-jit.ini

bruno@silverbook:/usr/local/etc/php/7.3/conf.d$ nano ext-xdebug.ini

[xdebug]
zend_extension="/usr/local/lib/php/pecl/20180731/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_handler=dbgp
xdebug.remote_port=9000

```

Chaque version de PHP a son propre répertoire d'extensions:

```bash
/usr/local/lib/php/pecl/20160303 ← 7.1
/usr/local/lib/php/pecl/20170718 ← 7.2
/usr/local/lib/php/pecl/20180731 ← 7.3
/usr/local/lib/php/pecl/20190902 ← 7.4
/usr/local/lib/php/pecl/20200930 ← 8.0

/usr/local/Cellar/php@7.4/7.4.14_1/pecl/20190902/
```

### Erreurs:

#### Warning: preg_replace(): JIT compilation failed: no more memory in

Il s'agit d'un [bug](https://bugs.php.net/bug.php?id=77260) connu de PHP 7.3.

2 solutions:

- désinstaller php 7.3
  `$ brew uninstall php@7.3`
- désactiver la compilation PCRE JIT dans le php.ini
  `pcre.jit=0`



Pour désactiver la compilation PCRE JIT, on peut aussi créer un fichier `fix-jit.ini` dans `/usr/local/etc/php/7.3/conf.d`et y ajouter:

```php
; My php.ini settings
; Fix for PCRE "JIT compilation failed" error
[Pcre]
pcre.jit=0
```
