[phpesp-general] Error enquiry

[Simon T. <si...@cp...>]

Hello all,

 I am try to setup the phpESP. Everything seems alright. I can create a
survey. But when i try to activate a survey, PHP prompted me a rror

"Fatal error: Call to undefined function: array_intersect()in
/usr/local/lib/php/contrib/phpESP/admin/include//where/status.inc on line
162 "

I have tried v.1.3 and v1.4. The problem is still exist. What's the problem?

The following screen capture is for your reference.
