Brand New to PHP... AND I haven't coded in a few years... :)

[Gregan]

Hi Everyone, I'm working on a project which will eventually work its way into a website design and came upon a color sorting problem. I found a potential great solution on Stack Overflow using the PHP language but I can't get the code to work. I've never coded in PHP and I've not coded much in years... I was wondering if someone could help me trouble shoot my code below?

 

Here is the stack overflow answer: http://stackoverflow.com/a/31742242/5807915, I didn't ask any further questions over there, that community intimidates me!

 

Here is my set of colors and the code that I've pulled together that I'm trying to get to work in this PHP http://phpfiddle.org/ code editor:

 

 

 

<?php
$colors = [
[ 'color'=> '# 000000 '],
[ 'color'=> '# 97233F '],
[ 'color'=> '# 841F27 '],
[ 'color'=> '# A71930 '],

Don't have a clue as to what you are attempting but...

 

Have you never worked with arrays before? You are supposedly creating an array with a character index value that is the SAME for every entry. What that means is your array will have only one entry - that being the last one you create.

 

Of course your whole syntax looks strange to me so I may be wrong. I'd look at the php manual to see how to create an array format that works for you.

 

The syntax I see mostly (and use) is:

 

$colors[] = "#000000";

$colors[] = "#000001";

 

Or

 

$colors = array(#000000,#000001,......);

 

These elements would then be referenced with with a foreach as you did or with a for command as in:

$maxclrs = count($colors);

for($i=0; $i<$maxclrs; $i++)

{

do something referencing $colors[$i]

}

 

Good luck!

I'm trying to take a bunch of color hex codes and then sort them into an order that makes sense in a color picker tool. The code I have above is all the colors I'm looking to sort, then it changes the hex value into RGB, then to HSL color codes that are then sorted. It apparently looks great once it executes properly. I'll try your syntax....

[ginerjm]

I tried this once. It ain't that easy!

[Gregan]

Try doing it when you don't code that often.

[QuickOldCar]

Somewhere in my old files I did this.

 

I created arrays with range() using 0-255 rgb values for every combination (16,777,216 possible color values), then conversions for 3 and 6 digit hex.

 

You can create this and save as an associative array, even better a database.

 

So your server doesn't puke...probably better off making 3 variables and cycle in chunks as groups to save into a database. Like 0,0,0 to 255,255,255

this will convert your existing $colors array to a simple indexed array ($newcolors)

$newcolors = array();
foreach ($colors as $color) {
    $newcolors[] = str_replace(' ', '', $color['color']);
}

[QuickOldCar]

Here is something that can actually store them, I looped just 10,000 of them.

I commented out the section for your loop and checking hue ranges.

function rgbToHsl($r, $g, $b)
{
$r /= 255;
$g /= 255;
$b /= 255;

$max = max($r, $g, $b);
$min = min($r, $g, $b);

$h = 0;
$l = ($max + $min) / 2;
$d = $max - $min;

if ($d == 0) {
$h = $s = 0; // achromatic
} else {
$s = $d / (1 - abs(2 * $l - 1));

switch ($max) {
case $r:
$h = 60 * fmod((($g - $b) / $d), 6);
if ($b > $g) {
$h += 360;
}
break;

case $g:
$h = 60 * (($b - $r) / $d + 2);
break;

I really appreciate you getting it to work and spit out a result, the output color arrangement isn't nearly as cool/clean as I had anticipated based on the original author's comments when he shared the code. Looks like I need to step away from this problem as it's well above my current abilities, I need to pass this onto someone else to solve when I find someone to code my actual website. Thanks again for your time and help.
