PHPSurveyor is a leading Open Source Online Survey Tool written in PHP. PHPSurveyor allows you to develop, publish and collect responses to surveys. PHPSurveyor includes a wide range of built-in question types, and a range of flexible options. Your surveys can include branching, your own preferred layout and design (using a templating system), and can provide basic statistical analysis of survey results. Surveys can be public, or can be strictly controlled through the use of once-only tokens for each survey participant.
