Question: Write the code inside this mimic_array_sum() function. That code should add up all individual numbers in the array and return the sum. You’ll need to use a foreach command to loop through the argument array, a working variable to keep the running total, and a return command to send the sum back to the main code
My Code:
function mimic_array_sum($array){
$count = 0;
foreach($array as $element){
$count = $count + 1;
$array[$count]= $array[$count] + $array[$count];
}
return $count;
}
$palindromic_primes = array(11, 757, 16361);

function mimic_array_sum($array){
$count = 0;
foreach($array as $element){
$count = $count + $element;
}
return $count;
}
$palindromic_primes = array(11, 757, 16361);
$count = mimic_array_sum($palindromic_primes);
$sum = $count;
echo $sum;

11,738 PointsNo problem Devin!
Again sorry to just give the answer and run man. I am working on a school project right now. :p If you have any particular questions on using the the foreach loop feel free to ask.
Did you specifically request for me to answer your question as my notification specified? If so I appreciate it man.
Here is a more detailed explanation of what is happening here,
//Create a new function call mimic_array_sum
function mimic_array_sum($array){
//Define the count variable and give it a default value of 0
$count = 0;
//call a foreach loop that loops through the $array
foreach($array as $element){
$count = $count + $element; //add each value in the array to the previous $count value
// the foreach loop does this for each value stored in the $array that is passed into the function
}
//after it's done it returns the total
return $count;
}
$palindromic_primes = array(11, 757, 16361); // Array that holds our three numbers
$count = mimic_array_sum($palindromic_primes);// The $palindromic_primes variable is then passed into the mimic_array_sum() function
$sum = $count; // Set the $sum variable to the return value from the mimic_array_sum() function
echo $sum; // echo the result

11,738 PointsThanks Devin! I appreciate it, and I hope this helps. PHP is a fun language; Especially when you start looking into how to use it with AJAX.

66,191 PointsHey arron, I have another problem that it would be helpful if you could help me solve.
Question: PalprimeChecker objects have a property called number. This task has two parts. First, assign that property a value of 17. Second, remove the two hash signs (##) in the first echo statement and instead concatenate the value of this number property. (Be sure to preserve the space after the two hash signs by concatenating a space after the number.)
My Code:
include "class.palprimechecker.php";
$checker = new PalprimeChecker(17);
echo "The number " + echo $checker;
echo "(is|is not)";
echo " a palprime.";

Can you please open a new forum question for your new question?
Thanks!
