Set background color in PHP

Question

What is the easiest way to set background color in PHP

User · Answer

CSS supports text input for colors  i e   black     000000  white     ffffff  So I think the helpful solution we are looking for here is how can one have PHP take the output from an HTML form text input box and have it tell CSS to use this line of text for background color   So that when a a user types  blue  into the text field titled  what is your favorite color   they are returned a page with a blue background  or whatever color they happen to type in so long as it is recognized by CSS   I believe Dan is on the right track  but may need to elaborate for use PHP newbies  when I try this I am returned a green screen no matter what is typed in  I even set this up as an elseif to display a white background if no data is entered in the text field  still green

This really depends on what you need to do  If you want to set a background colour on a page then you need to use CSS as per Jay s and David Dorward s answers   If you are building an image with PHP then you can use the GD library to allocate colours yourself  I don t recommend this without thoroughly reading up on how to create images with GD  http   www php net manual en function imagecolorallocate php
