php - Removing DateTime/Object from DatePeriod -


i'm trying create filter, whereby if days (monday, tuesday etc) not found in list, want specific datetime removed dateperiod. can say, work monday , tuesday. if find day thursday, continue out of loop , don't include it.

however, cannot seem when iterate through dateperiod, cannot unset anything, not count array. there way this? code can found below:

//get start , end dates of holidays (this run iteratively)   $get_st_date = $row['h_s_date']; $get_end_date = $row['h_e_date']; //convert them approprariate format used dateperiod    $get_begin = new datetime( "$get_st_date" ); $get_end = new datetime( "$get_end_date");  //add day or else omitted following process. $get_end = $get_end->add(new dateinterval('p1d')); //count per day $get_interval = dateinterval::createfromdatestring('1 day'); $get_period = new dateperiod($get_begin, $get_interval, $get_end); //iteration count $iter = 0; foreach($get_period $get_dt){     //find if date  saturday or sunday. if is, break current loop.     $iter++;     $str_result = $get_dt->format('l');     if($str_result == "saturday") {continue;}     elseif($str_result == "sunday") {continue;}     elseif(!preg_match("($str_result)", $e_d_w_p_w)){         echo "<br>don't count day" . $str_result;          unset($get_period[$iter]);          continue;     }

then close end tags (i haven't included here other stuff.

from above code, following error: "fatal error: uncaught error: cannot use object of type dateperiod array"

is there workaround this?

for clarification: $e_d_w_p_w "employee days worked per week"
$e_d_w_p_w formatted "monday;tuesday;" etc

the problem dateperiod not array, error says. has properties required make list of days required, doesn't store them, can't unset() specific day list.

what can accomplish create new array, , instead of removing days not match criteria dateperiod, add days new array:

<?php $get_st_date = "2017-09-01"; $get_end_date = "2017-09-20"; //convert them approprariate format used dateperiod    $get_begin = new datetime( "$get_st_date" ); $get_end = new datetime( "$get_end_date");  //add day or else omitted following process. $get_end = $get_end->add(new dateinterval('p1d')); //count per day $get_interval = dateinterval::createfromdatestring('1 day'); $get_period = new dateperiod($get_begin, $get_interval, $get_end);  $e_d_w_p_w = "monday;tuesday;"; $workdays = []; //iteration count $iter = 0; foreach($get_period $get_dt) {     //find if date  saturday or sunday. if is, break current loop.     $iter++;     $str_result = $get_dt->format('l');     if($str_result == "saturday") {continue;}     elseif($str_result == "sunday") {continue;}     elseif(preg_match("($str_result)", $e_d_w_p_w)){         $workdays[] = $get_dt;     } } var_dump($workdays);

demo

also, think might bit cleaner (and faster; avoid regular expressions whenever possible) transform $e_d_w_p_w array , check if current day in array:

$e_d_w_p_w = "monday;tuesday;"; $days = explode(";", $e_d_w_p_w); // transform array, separating ; array_pop($days); // remove last element (assuming have trailing ;

and then

elseif(in_array($str_result, $days)){     $workdays[] = $get_dt; }

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
