Hi, I'm trying to sort an array of colors based on their group/category. But, unfortunately, the sorted colors are not linear. So here's some codes for your reference. Function: sortColors: function sortColors($colors) { $s = $hue = $sat = $val = $final = []; foreach($colors as $k => $info) { $color = $info['hex']; $hex = strtolower(str_replace('#', '', $color)); $info['hex'] = $hex; $colors[$k] = $info; list($r, $g, $b) = str_split($hex, 2); $r = hexdec($r); $g = hexdec($g); $b = hexdec($b); //$s[$k] = rgbtohsv($r, $g, $b); $s[$k] = rgbToHsl($r, $g, $b); $info['hex'] = "#$hex"; } //Split each array up into H, S and V arrays foreach($s as $k => $v) { $hue[$k] = $v['h']; $sat[$k] = $v['s']; $val[$k] = $v['l']; //$val[$k] = $v['v']; } $r = $s; $keys = array_keys($r); uasort( $r, function($a, $b) { if(!huesAreinSameInterval($a['h'],$b['h'])){ if ($a['h'] < $b['h']) return -1; if ($a['h'] > $b['h']) return 1; } if ($a['s'] < $b['s']) return -1; if ($a['s'] > $b['s']) return 1; if ($a['l'] < $b['l']) return 1; if ($a['l'] > $b['l']) return -1; return 0; } ); $i = 0; foreach($r as $k => $hsv) { $info = $colors[$k]; $hex = $info['hex']; $info['hex'] = "#$hex"; $info['hsv'] = $hsv; $final[] = $info; $i++; } return $final; } Input Array of Colors: Array ( [0] => Array ( [name] => Black [hex] => #000000 ) [1] => Array ( [name] => White [hex] => #FFFFFF ) [2] => Array ( [name] => Red [hex] => #FF0000 ) [3] => Array ( [name] => Red Devil [hex] => #860111 ) [4] => Array ( [name] => Pink [hex] => #FFC0CB ) [5] => Array ( [name] => Blue [hex] => #0000FF ) [6] => Array ( [name] => Lavender Blue [hex] => #CCCCFF ) [7] => Array ( [name] => Mint Green [hex] => #98FF98 ) [8] => Array ( [name] => Lincoln Green [hex] => #195905 ) [9] => Array ( [name] => Electric Yellow [hex] => #FFFF33 ) ) Output of the Sorted Array: Array ( [0] => Array ( [name] => White [hex] => #ffffff [rgb] => Array ( [r] => 255 [g] => 255 [b] => 255 ) [hsl] => Array ( [h] => 0 [s] => 0 [l] => 1 ) [hsv] => Array ( [h] => 0 [s] => 0 [l] => 1 ) ) [1] => Array ( [name] => Black [hex] => #000000 [rgb] => Array ( [r] => 0 [g] => 0 [b] => 0 ) [hsl] => Array ( [h] => 0 [s] => 0 [l] => 0 ) [hsv] => Array ( [h] => 0 [s] => 0 [l] => 0 ) ) [2] => Array ( [name] => Red [hex] => #ff0000 [rgb] => Array ( [r] => 255 [g] => 0 [b] => 0 ) [hsl] => Array ( [h] => 0 [s] => 1 [l] => 0.5 ) [hsv] => Array ( [h] => 0 [s] => 1 [l] => 0.5 ) ) [3] => Array ( [name] => Electric Yellow [hex] => #ffff33 [rgb] => Array ( [r] => 255 [g] => 255 [b] => 51 ) [hsl] => Array ( [h] => 60 [s] => 1 [l] => 0.6 ) [hsv] => Array ( [h] => 60 [s] => 1 [l] => 0.6 ) ) [4] => Array ( [name] => Lincoln Green [hex] => #195905 [rgb] => Array ( [r] => 25 [g] => 89 [b] => 5 ) [hsl] => Array ( [h] => 105.71429 [s] => 0.89362 [l] => 0.18431 ) [hsv] => Array ( [h] => 105.71429 [s] => 0.89362 [l] => 0.18431 ) ) [5] => Array ( [name] => Mint Green [hex] => #98ff98 [rgb] => Array ( [r] => 152 [g] => 255 [b] => 152 ) [hsl] => Array ( [h] => 120 [s] => 1 [l] => 0.79804 ) [hsv] => Array ( [h] => 120 [s] => 1 [l] => 0.79804 ) ) [6] => Array ( [name] => Lavender Blue [hex] => #ccccff [rgb] => Array ( [r] => 204 [g] => 204 [b] => 255 ) [hsl] => Array ( [h] => 240 [s] => 1 [l] => 0.9 ) [hsv] => Array ( [h] => 240 [s] => 1 [l] => 0.9 ) ) [7] => Array ( [name] => Blue [hex] => #0000ff [rgb] => Array ( [r] => 0 [g] => 0 [b] => 255 ) [hsl] => Array ( [h] => 240 [s] => 1 [l] => 0.5 ) [hsv] => Array ( [h] => 240 [s] => 1 [l] => 0.5 ) ) [8] => Array ( [name] => Red Devil [hex] => #860111 [rgb] => Array ( [r] => 134 [g] => 1 [b] => 17 ) [hsl] => Array ( [h] => 352.78195 [s] => 0.98519 [l] => 0.26471 ) [hsv] => Array ( [h] => 352.78195 [s] => 0.98519 [l] => 0.26471 ) ) [9] => Array ( [name] => Pink [hex] => #ffc0cb [rgb] => Array ( [r] => 255 [g] => 192 [b] => 203 ) [hsl] => Array ( [h] => 349.52381 [s] => 1 [l] => 0.87647 ) [hsv] => Array ( [h] => 349.52381 [s] => 1 [l] => 0.87647 ) ) ) Any help will be appreciated.

Hello again, I've got a problem with PHP GD. The problem is I'm trying to draw charts (i.e.Bar) and I'm trying to draw the Bell Curve of a data or an array with "Normal Distribution", but the problem is the chart is not fitting inside the allocated image size (1920 x 1080) so the chart is exceeding the boundaries of the image. So I've just tried a library "JpGraph" it works very well but doesn't fit my requirements, so I saw that the library is using some kind of canvas to draw the chart and then merging the image with the original one and I'm trying to do the same but I couldn't understand how. Please help me out, it's very urgent, I've to finish the project within a week. public function histogram(array $samples, int $bins, string $heading = null, string $xAxisHeading = null, string $yAxisHeading = null) { if(is_array($samples)) { $data = $_bins = $this->calculateBins($samples, $bins);

I am trying to install Hubzilla Server on my account and it's spitting out three critical errors (exec disabled, shell_exec disabled, and could not find a command) that I can't get past. Now, before you reply, I understand why you would not want shell_exec and exec enabled. I am not a PHP programmer by any means, but I understand the potential security concern here. So, now, my question: Hubzilla is pretty feature rich and decentralized. The decentralized aspect is what I was looking for. Is there another decentralized social network, even one not offered through the Softaculous easy installer, that would not require shell_exec and exec enabled?

Is it possible to create a database through MySQL commands using PHP here? Look at this situation: I want the clients to create a database with the click of a button, containing several preset tables, using SQL commands inside PDOs in PHP. That being said, I want those databases to be created automatically, because this is part of a customized simple application.
