Generate random RGB color code in PHP

Greetings Programmers, in this tutorial we will see how to generate random RGB color code in PHP.

The RGB color model stands for Red, Green, and Blue respectively which are the primary colors of light. These colors when mixed in different proportions create a new set of colors which can be helpful for a designer to complete its design.

This RGB color model consists of a set of three values ranging from 0 to 255 with 0 and 255 inclusive.

Generating Random RGB Colors in PHP

We can generate random colors using a random function between the range 0 to 255 for the main primary colors red, green, and blue.

We use the above function to generate the random colors in RGB format by concatenating them with the corresponding values in a specified range of values.

We can call the following function above and generate the colors.

$rndColor = rndRGBColorCode(); #function call echo $rndColor;

Using random color generated for the background of web page

In the following program, we will generate a random RGB color using random values and string manipulations.

 #driver $rndColor = rndRGBColorCode(); #function call $valPrint = '
The color is: ' . $rndColor . '
'; #value print $colorPage = sprintf(' body ', $rndColor); #bg color shade echo $valPrint . $colorPage; #printing result ?>

Explanation
The ‘rndRGbColorCode()’ function generates the random set of three values ranging from 0 to 255 and concatenated with the string ‘RGB’ using string manipulations. We call the function and print the randomly generated RGB value. Correspondingly, we set the background color using HTML and CSS syntax with the randomly generated RGB color code. On each refresh of the page, random colors are generated and depicted in the background of the webpage as well as the code is displayed over it.

For generating attractive random colors.

This is a PHP port of David Merfield randomColor Javascript utility.

You can pass an options object to influence the type of color it produces. The options object accepts the following properties:

hue – Controls the hue of the generated color. You can pass a string representing a color name (e.g. ‘orange’). Possible color names are red, orange, yellow, green, blue, purple, pink and monochrome. You can also pass an array of multiple hues or a specific hue (0 to 360).

luminosity – Controls the luminosity of the generated color. You can pass a string containing bright, light or dark.

format – A string which specifies the format of the generated color. Possible values are hsv, hsl, hslCss, rgb, rgbCss, and hex.

prng – A random (or not) number generator. mt_rand is used as default one.

use \Colors\RandomColor; // Returns a hex code for an attractive color RandomColor::one(); // Returns an array of ten green colors RandomColor::many(10, array( 'hue' => 'green' )); // Returns a hex code for a light blue RandomColor::one(array( 'luminosity' => 'light', 'hue' => 'blue' )); // Returns one yellow or blue color RandomColors::one(array( 'hue' => array('yellow', 'blue') )); // Returns a hex code for a 'truly random' color RandomColor::one(array( 'luminosity' => 'random', 'hue' => 'random' )); // Returns a bright color in RGB RandomColor::one(array( 'luminosity' => 'bright', 'format' => 'rgbCss' // e.g. 'rgb(225,200,20)' ));

How to Generate Random color Functions in PHP?

In this blog, I am going to start how to generate Random color Functions in PHP? we’re going to be talking about functions now functions really give some functionality. Functions can take a block of code and execute it whenever it needs to be executed.

So, here we have a simple function. And over here we’re calling over to that function and we get an output dependent on what’s happened that function. So within this code, we’re actually going to build a function and we’re going to call to that function and it’s going to change.

Set a random color to a background of some HTML code. So the first thing that we want to do is we’re going to set up a function and we’re just going to call that function random color and again between these curly brackets this is the code that’s going to get executed when we call these are custom functions. PHP also has quite a few built-in functions and several of them we’ve been using in the past.

So now I’m going to echo notes the div I need to get that style so going to give it an inline style and give it background.

I call that string and here I’m just going to set I was going to call over to the random color or if I wanted to I could just set a color this way.
And for now, we’re going to do it this way and we’re going to update that later on as well to shorten remember again we have to close quote it because this is a style. So we’re using a combination of single and double-quotes. This will be a random background called and close off that div and close. I’m also going to add in some padding here just to make it a little bit bigger.

I’m going to just set this random color to something like that and I’m going to return our color so, that this way we’re actually returning something here and we’re going to get a value in that background color.
In this function, I am using six random characters colors.

For color check you can refresh page as multiple time, color will be change multiple time.

For random color you can use 3, 4, 8, random characters as shown below-

Генерация случайного цвета PHP

Здравствуйте, уважаемые форумчане, помогите с вопросом, я не сильно разбираюсь в PHP, но жду от Вас небольшой помощи. Есть задача, написать код для случайной генерации цвета в RGB и вывести в цикле 10 div с разными цветами. Функцию написал, цвет меняет, но проблема с циклом — выводит все div разом и они одного цвета, подскажите что можно поменять? Спасибо

function random_html_color() { return sprintf( '#%02X%02X%02X', rand(0, 255), rand(0, 255), rand(0, 255) ); } $d = '
'; $x = 1; while ($x  10): echo $d; $x++; endwhile;
