jr_alivio here’s a quick one:
[php]
<?php
$box = imagecreatefromjpeg(‘test.jpg’);
$bxw = imagesx($box);
$bxh = imagesy($box);
$pixels = array();
for ($i = 0; $i < $bxh; $i++) {
for ($j = 0; $j < $bxw; $j++) {
$color = dechex( imagecolorat($box, $j, $i) );
$colorl = strlen($color);
if ($colorl < 6) {
$color = str_repeat(‘0’, 6 - $colorl) . $color;
}
if (array_key_exists($color, $pixels)) {
$pixels[$color]++;
} else {
$pixels[$color] = 1;
}
}
}
asort($pixels);
$common_color = end( array_keys($pixels) );
$color_count = array_pop($pixels);
echo “The common color is: #$common_color with $color_count count(s).”;
?>[/php]
my idea basically is, you record the values in an array, with the array key being the color itself, if the array key exists, then you just increment its value, if it’s not, then you add it to the array, then at the end, you just sort the array and get the end element.
