[RESOLVED] simple question

[jasondavis]

function findfriend() {
	$temp = $_SESSION['info'];
	$sql_friend = "select friendid from friend_friend where userid=$temp[auto_id] and status=1";
	$result_friend = executeQuery($sql_friend);
	while ($line_friend = mysql_fetch_array($result_friend)) {
		$friend[] = $line_friend['friendid'];
}





if (findfriend() != '') {
			$str_friend_ids = findfriend();
}

Is my code running the findfriend function 2 times?

[ahundiak]

No.

Edited: Oops. NogDog is absolutely correct. The function will be called twice.

[NogDog]

Yes.

If it evaluates as != '' in the if condition, then it's running once there and then again in the command within that if block.
