Stopping Loop Help?

[twilitegxa]

I have the following code that cycles though and prints out the day of the week and stops printing after the seventh day is reached, but it keeps looping. How do I stop it from looping after 7? I thought I had it right, but it's not. Can anyone help?

 

 

<?php


$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");


echo current($weekdays) . "<br />";
while (count($weekdays) <  {
echo next($weekdays) . "<br />";
}


?>

count($weekdays) is not going to change. It is the number of entries in the array.

 

try using foreach instead

$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");

foreach($weekdays as $wkDay) {
  echo $wkDay . "<br />";
}

$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");

echo current($weekdays) . "<br />";
$i = 0;
while ($i < count($weekdays)) {
echo next($weekdays) . "<br />";
$i++;
}

OR

 

$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");

for($i = 0; $i < count($weekdays); $i++) {
  echo $weekdays[$i] . "<br />";
}

* Not really recommended since the count() will be executed every time the loop starts.

 

Or, if you like writing code that is on one line and difficult to read or maintain:

 

$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");

for($i = 0; $i < count($weekdays); echo $weekdays[$i++] . "<br />")  ;

* Also NOT recommended

 

by the way, if you are going to use next(), you should probably use reset() instead of current() for the first one. If you try to execute the loop a second time without a reset, the pointer will be at the end of the array and you will get an error:

 

$weekdays = array("Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday");

echo reset($weekdays) . "<br />";
$i = 0;
while ($i < count($weekdays)) {
  echo next($weekdays) . "<br />";
  $i++;
}

Of course, you're still using count within the loop. Not that it matters much in such a small array.

 

Personally, I'd use the foreach and increment a variable if I needed to keep track of numbers. 1st reply, simple and effective.
