[CentOS] PHP version not enough for developers

[Kai Schaetzl]

I've been using IUS in the past. They have a good way of naming their 
rpms, so they don't interfere with the RH rpms. But they don't support 
older CentOS versions still on extended support as long as I needed them. 
And they don't provide as much php-related rpms (f.i. pecl-stuff) as remi 
does.
So, with newer PHP versions I had to go to remi's repo. Combined with EPEL 
(and rpmforge being dead, anyway) it's working quite fine here for PHP 5.5 
and 5.6. He provides files for CentOS 5, 6 and 7. The only caveat is that 
he uses the same rpm names as with the original ones. So, you have to give 
this repo the same priority as the base repo has. In consequence you have 
to be careful what it wants to install as dependencies and exclude a 
package sometimes. But all in all it works very well.

I've used the webtatic repo once for a special case. I don't know exactly 
why but I wouldn't recommend it.

If IUS provides the version you need I'd go with that.
