Developer Stefan Esser has launched his Month of PHP Bugs project with 
11 bugs in five days, including an old flaw reintroduced in a new 
version of PHP and several known bugs he says are unlikely ever to be 

Esser and his collaborators published eight flaws in the first three 
days of the month, followed by another three on Sunday and Monday. 
Unlike similar, but unconnected, projects such as the Month of Kernel 
Bugs and the Month of Apple Bugs, "we do not enforce a 
one-vulnerability-per-day limit upon ourselves," Esser wrote on the

server, monitoring PHP applications and reporting on performance and 
possible problems.

Zend, which sponsors PHP development, has criticised Esser for his 
aggressive attitude toward PHP developers, but Esser said others have 
been supportive, with several developers volunteering their own zero-day 
flaws for publication.

"The reaction has been quite positive so far," he wrote in a blog post.
