Description: ------------ When filtering CSV data with connect(array()) I have encountered a strange bug. In your code you use $columns === array() which does not work and always returns false. I replaced it with is_array() function and everything works as supposed. Test script: --------------- $arr = array("a","b","c"); if(is_array($arr) return "ok\r\n"; if($arr === array()) return "array too"; //prints ok Expected result: ---------------- ok array too Actual result: -------------- ok Just note - you miss PHP version 5.2.17 so I chose the rearst option.
