## [PHP] Solving Euler Project #2

The Problem - "Find the sum of all the even-valued terms in the Fibonacci sequence which do not exceed four million."

The Solution [PHP]<?php

/*********************************

*********************************/
\$first = 0; // Here are the two numbers that...
\$wing = array(); // Keeping ***** of the even-numbered Fibonacci numbers
for (\$i=0; \$i<=**; \$i++) {
\$fibonacci = \$first + \$second; // 0+*, *+*, *+2, 2+*
\$first = \$second; // 0-->*, *-->*, *-->2, 2-->*
\$second = \$fibonacci; // *-->2, 2-->*, *-->5, 5-->8
echo "\$fibonacci <br>";
if ((\$fibonacci &#*7; 2) == 0) { // If the current Fibonacci number is even
\$wing[\$i] = \$fibonacci;
} else {
echo "";
}
}
\$arraysum = array_sum(\$wing); // Add 'em all up!
echo "<hr>" . \$arraysum;

After doing a lot of other stuff (using programming and my knowledge of F****occi numbers alone) I got to the final stopping point of **. Since this was my final solution (lolololol insart hitler joke hear) I wanted to make it not have to do more than was needed. I guess I should've done what you did and kept ***** of the current F****occi number to make sure it wasn't over 4,000,000.  Reply With Quote
