i'm learning php , have file connects mysql database, i'd know condition inside brackets of following "if structure" in file, $con instance of class mysqli: if ($con->connect_errno) { echo "fail connect mysql"; } i know $con invoking connect_errno conditioning if(what?){...}? that's status flag mysqli handles. see http://php.net/manual/en/mysqli.connect-errno.php it's not function, property (or "variable" if will). it's 0 when connection correctly established. contains other values (e.g. 1043 ) connection problems (such wrong password, inavailable database server). so if ($con->connect_errno) check asserts $con instance usable. when ->connect_errno == 0 if block skipped. if ->connect_errno > 0 (any other value) error message printed out. (you'd more commonly see die() , trigger_error() or new exception() echo there.) alternatively mysqli can configured throw error/exception itsel

this thought experiment, not production code nor coding style. suppose have function int find_process_pid_by_name(char* name, int* threads_in_process); that return pid of named process , store threads_in_process number of threads running in said process. a lazy programmer, interested on pid , writes code int pid = find_process_pid_by_name("a process name", &pid); does trigger undefined behavior? no — don't think undefined behaviour. there's sequence point before function called (after arguments , expression denotes called function have been evaluated), , there's before called function returns. side-effects on pid performed called function have been completed before function finishes returning. result of function assigned pid . there's no question of location assigned being changed function. see nothing invokes undefined behaviour. i assuming called function treats int * argument write-only pointer single value. if rea
