Suggested change for array_filter

My writing abilities aren't very good, but I'm fairly unhappy with the current documentation for array_filter, so I'm going to propose a general direction the page might take and then hope that someone with some actual ability to write will step up and deliver the goods. If not, I'm sure I'll get around to it at some point. --------------------------------------------------------------- array_filter iterates over the values stored in input, passing them to the callback function. The current value will be copied to the result array if function returns true. If the input is an associative array the keys are preserved. --------------------------------------------------------------- The general idea being to document: 1) 'callback' will be iteratively passed one argument, the value of the current array index. 2) If callback returns true, the value of the current array index will be copied into the result array.
