Question

I have a mysql database with a string field called “color” from java
I keep the value so:

// (2=color field)
pst.setString (2, objeto.getBackground (). getRGB ())

and then I read it like this:

objeto.setBackground (Color.decode (rs.getString ("color")))

Is there any function in mysql or php to read the color?

Answer 1

What do you want exactly?

Convert a int to a color in #RRGGBB format?

sprintf('#%06X', $color); 

or get the R, G, B values?

$r = ($color >> 16) & 0xFF;
$g = ($color >> 8) & 0xFF;
$b = ($color >> 0) & 0xFF;

or create a int from rgb values

$color = ($r & 0xFF) << 16 | ($g & 0xFF) << 8 | $b & 0xFF
