php - comparison array doesnt work -

-

i have code i'm trying compare $current $password array , thought both have same value , doesn't work.

$current_password = mysqli_query($db_connection,"select password                                      user username  = 'sanket' "); $row = mysqli_fetch_array($current_password); foreach($row $pass) {     $password = $pass[0]; } $current = $_post['old_password']; if ($current == $password) {      if ($_post['new_password'] == $_post['confirm_password']) {      mysqli_query($db_connection,"update user set password     = ".$_post['confirm_password']."   username  = 'sanket'") ;  } 

$row = mysqli_fetch_array($current_password); foreach($row $pass) {     $password = $pass[0]; }

$row unidimensional array strings. when foreach on $row $pass string. when assign $pass[0] $password, assign first character of string in $pass $password. write:

$row = mysqli_fetch_array($current_password); $password = $row[0];

and here necessary warning: use proper escaping mysqli_prepare or mysqli_real_escape_string user input!

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
