Using arrays and foreach statements {SOLVED}

Beginners - Learning PHP
#1

Ok to explain what is happening “$total” is an equation of a percentage that im mulitplying with the “$value” if the total is greater than 100% it makes the number bigger than 333, 300, 166. I don’t want the values to be any bigger than the array values. I know the below code works.

[php]

<?php $arkonor1 = array("$mega" => 333, "$trit" => 300, "$zyd" => 166); ?> <?php foreach($arkonor1 as $key1 => $value1) { $get = floor($value1*$total); echo ""; } ?>

<?php include('name.php'); ?>
$key1 $get
[/php]

so i was thinking of adding something like this but was unsure how to do it any suggestions.

[php]

<?php if ($get >= 333) echo "333"; else echo $get; ?>

[/php]

my other problem is I need to make the value a variable for other things that i need to do to it. So if the percentage is equal to 97% it take (333*.97) = 323.01 and then make this a variable. Hope i was able to explain it ok to understand. Thank in advance

If you want to use the value in the variable to be no greater than a predetermined value, you could use something like this:

[php]
if ($variable >= 333) { $variable = 333; }
echo $variable;
[/php]

Your last question tells me you’re not a pro in PHP though ;) Once assigned, a variable keeps its value until either:

  • unset() is called on the variable
  • the variable gets a new value assigned to it
  • the script stops running

Thank you for the code it works great for the first number but when the foreach statement loops back to the second value in the statement i need to make that number no highter than 300 and same thing for the 3rd time where that number can’t be higher than 166. any suggestions. Thanks

[php]
$maxvalues = array(
333,
300,
166
);

for ($i = 0; $i < count($maxvalues); $i++) {
if ($variable >= $maxvalues[$i]) { $variable = $maxvalues[$i]; }
}
[/php]

Seriously, this is basic PHP & array knowledge (dare I say, a no-brainer?). You should easily be able to come up with something like this if you can figure out the foreach() loop (or associated arrays for that matter).

#5

Ok not sure what happened or what i miss typed but the only value that is showing up 3 times in a row is 166. Why would this be happening.

[php]
$arkvalues = array(333, 300, 166);

<?php foreach($arkvalues as $variable) { $variable1 = floor($variable*$total); for ($i = 0; $i < count($arkvalues); $i++) { if ($variable1 >= $arkvalues[$i]) { $variable1 = $arkvalues[$i]; } } echo " $variable1"; } ?>

[/php]

#6

I was able to solve it with this code but thanks for the help.

[php]
foreach($arkvalues as $var)
{
if ($total < 1)
$var = floor($var*$total);
echo “

$var”;
}
[/php]
