The International PHP Magazine has posted the results of their latest question to the community - which of the options given is the main hindrance for PHP5's adoption.
Options included "PHP5 does not support CMS", "PHP5 is slow", and "PHP4 fulfills all the needs". The option that came out on top, however, was "The user's ISP is old and not updated to support newer versions" with 49.5 percent of the votes. Coming in behind it was the "none" option which might suggest that PHP5 adoption isn't all that slow anymore.
They've also started up their newest poll asking which of the listed features are ones that developers would like to see in PHPUnit the most (including the options "Mutation testing" and "support for distributed testing").
