如何将PHP5.5降级为5.4或5.3在centos6上

Question

我有服务器运行centos 6，最近我将服务器上的php升级到5.5版本，并注意到我使用的laravel框架中的一些脚本正在中断。我知道这个错误

Parse error: syntax error, unexpected 'yield' (T_YIELD), expecting '(' in /var/www/vhosts/jpischolarship.com/httpdocs/laravel/helpers.php on line 563

在做了一些研究之后，我发现我使用的框架中有一个名为“产”的方法，它现在是php 5.5中的一个保留关键字。

如何将当前的php安装降级到以前的版本？我试过"yum downgrade php“却没有运气。我得到以下输出

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Answer 1

你得跑：

 "sudo yum downgrade php php-common php-cli"

Answer 2

与原子回购不同的CentOS与php的方式。由于原子上没有旧的5.3，所以需要进行不同的回购。我用了http://webtatic.com。

安装回购程序：

rpm -Uvh http://mirror.webtatic.com/yum/centos/5/latest.rpm

安装gpg键：

rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy

编辑原子回购：

vi /etc/yum.repos.d/atomic.repo

为原子添加php排除：

[atomic]
exclude=php,php-common,php-*

编辑网页策略回购：

vi /etc/yum.repos.d/webtatic.repo

更改回购设置：

[webtactic]
enabled=1

现在降级php：

yum downgrade php, php-*

为我工作过。
