我的服务器运行的是 centos 6,我最近将服务器上的 php 升级到了 5.5 版,发现我使用的 laravel 框架中的某些脚本出现了问题。我收到此错误
Parse error: syntax error, unexpected 'yield' (T_YIELD), expecting '(' in /var/www/vhosts/jpischolarship.com/httpdocs/laravel/helpers.php on line 563
经过一番研究,我发现我使用的框架有一种名为“yield”的方法,它现在是 php 5.5 中的保留关键字。
如何将当前安装的 php 降级到以前的版本?我尝试过“ yum downgrade php
”,但没有成功。我得到了以下输出
Loaded plugins: fastestmirror, priorities

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
答案1
您需要运行:
"sudo yum downgrade php php-common php-cli"
答案2
CentOS 上采用来自 atomic repo 的 php 的不同方法。由于 atomic 上没有旧的 5.3,因此您需要不同的 repo。我使用了http://webtatic.com。
安装 repo:
rpm -Uvh http://mirror.webtatic.com/yum/centos/5/latest.rpm
安装 gpg-key:
rpm --import http://repo.webtatic.com/yum/RPM-GPG-KEY-webtatic-andy
编辑原子仓库:
vi /etc/yum.repos.d/atomic.repo
为原子添加 php 排除:
[atomic]
exclude=php,php-common,php-*
编辑 webtactic 仓库:
vi /etc/yum.repos.d/webtatic.repo
更改 repo 设置:
[webtactic]
enabled=1
现在降级 php:
yum downgrade php, php-*
对我有用。
