问题 This is a super simple array print, but I'm getting at the end when I use print_r. <?php $user_names = array(1, 2, 3, 4); $results = print_r($user_names); echo $results; ?> Then I get: Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 ) 1 回答1: print_r already prints the array - there is no need to echo its return value (which is true and thus will end up as 1 when converted to a string): When the return parameter is TRUE, this function will return a string.

问题 PagesPrinted field of job_info_2 not reliable for hp printers on windows 7, value depends on print processor I'm developping a print monitor, and for hp printer PagesPrinted is not reliable et has wrong values 回答1: The print driver for your printer is apparently calling SetJob with incorrect page count values.
