i'm aware if you're inserting variable, use mysqli_real_escape_string. but, if i'm inserting fixed value not variable, need use function? for example, syntax below. insert name variable, , value '1' status column. safe avoid sql injection column status? since not variable. "insert customer(name, status) values ('".mysqli_real_escape_string($conn, $name) ."', '1')"; when using mysqli, safest use prepared statements: $stmt=$mysqli->prepare("insert customer(name, status) values (?, '1')"; $stmt->bind_param("s", $name); (see http://php.net/manual/en/mysqli.quickstart.prepared-statements.php more detailed , working code). in can leave static values is, nobody can replace those. can alter table: alter table customer alter column status default '1'; then not have set longer.

for background, playing through untrusted , javascript-based programming game core mechanic editing code modify game world progress forward. have solved levels "intended" way modifying variables given in local scope using documented in-game api. however, wondering if there "unintended" ways modify game state/game definition fishing around. a lot of game has code follows (evaluated in window scope): function foo() { var bar = 1234; } i understand can access foo scope referring window.foo . there way can access bar inside foo though not explicitly exposed? to clarify, above code evaluated me (in window scope, believe, can @ least reference foo ). can not change evaluated. (i suppose redefine foo if wanted, , bypass lot of restrictions, that's tangential current direction of questioning.) rather, goal is, given has been evaluated, modify in place (such setting new value bar ). thanks in advance! the short answer no . it's not ...

if have data frame so 4 6 6 0 4 5 0 0 6 5 0 4 4 4 but lot bigger, command can write delete row 0's, such row 4 in example. in end this 4 6 6 0 4 5 6 5 0 4 4 4 thanks! something this? df[apply(df[, sapply(df, is.numeric)], 1, function(x) !all(x==0)), ] or df[rowsums(abs(df[, sapply(df, is.numeric)])) != 0, ] example: > df <- data.frame(x=c(1, 2, 0), y=c(0, 1, 0), z=letters[1:3]) > df x y z 1 1 0 2 2 1 b 3 0 0 c > df[rowsums(abs(df[, sapply(df, is.numeric)])) != 0, ] x y z 1 1 0 2 2 1 b
