• I want to convert the HEX value to HSL. From the following function, when I passed directly the value `fff000`, then the outcome hsl value is correct, but when I passed `#fff000` then the outcome hsl value is incorrect.

The problem came from `#`. I wonder how I remove the `#` from the get_sub_field. As an instance `<?php \$hex_color = get_sub_field('hex_color');?>`

``````<?php

function hexToHsl(\$hex){
\$red = hexdec(substr(\$hex, 0, 2)) / 255;
\$green = hexdec(substr(\$hex, 2, 2)) / 255;
\$blue = hexdec(substr(\$hex, 4, 2)) / 255;

\$cmin = min(\$red, \$green, \$blue);
\$cmax = max(\$red, \$green, \$blue);
\$delta = \$cmax - \$cmin;

if (\$delta == 0) {
\$hue = 0;
} elseif (\$cmax === \$red) {
\$hue = ((\$green - \$blue) / \$delta);
} elseif (\$cmax === \$green) {
\$hue = (\$blue - \$red) / \$delta + 2;
} else {
\$hue = (\$red - \$green) / \$delta + 4;
}

\$hue = round(\$hue * 60);
if (\$hue < 0) {
\$hue += 360;
}

\$lightness = ((\$cmax + \$cmin) / 2);
\$saturation = \$delta === 0 ? 0 : (\$delta / (1 - abs(2 * \$lightness - 1)));
if (\$saturation < 0) {
\$saturation += 1;
}

\$lightness = round(\$lightness*100);
\$saturation = round(\$saturation*100);

return "hsl(\${hue}, \${saturation}%, \${lightness}%)";

//return array(\$hue, \$saturation, \$lightness);
}
\$hex_color = 'fff000';
echo hexToHsl(\$hex_color);``````
