problem with array???

[kumschick]

hi,

I have 2 small problems.

First of all, if I do an foreach() { echo"value,"; } , how can I take the last "," away?

exemple: "ar1,ar2,ar3,ar4," ??? I just want to remove the last ",".

then same formula, but other problem with system("");

I want to put the output of the array into the system() put it don't work.???

<?php

$weekday[0] = "m"; //monday
$weekday[2] = "w" // w....
$weekday[5] = "s";
$weekday[6] = "su";
$time_h = "16";
$time_m = "30";

function get_weekday($weekday) {

  if(is_array($weekday)) {
    foreach ($weekday as $value) {
      echo"$value,";
    }
  }

}

system("at $time_h:$time_m /every:get_weekday($weekday) \"c:/test.bat\"");

?>

How do I fix this problems? Thx for any help

foreach isn't needed. Use [man]implode[/man].

Plus, you need to return from a function to get a value. Not echo. Using implode, a function isn't needed.
