PHP Application: Display Web-safe Colors

PHP - PHP Hypertext Preprocessor

Web-safe color codes include the following RGB values:

  • 0x00
  • 0x33
  • 0x66
  • 0x99
  • 0xCC
  • 0xFF

The following PHP script generates a table for displaying the websafe colors:

<?php
// Color value definitions
$c = array('00','33','66','99','cc','ff');
// Start color table
echo '<table border="1" cellpadding="6">';
// Iterate R(ed) values
for ($i 0$i 6$i++)
{
    
// Iterate G(reen) values
    
for ($j 0$j 6$j++)
    {
        
// Start color table row
        
echo '<tr>';
        
// Iterate B(lue) values
        
for ($k 0$k 6$k++)
        {
            
// Get color value
            
$color $c[$i].$c[$j].$c[$k];
            
// Get "inverted" color value
            
$colorinv $c[5-$i].$c[5-$j].$c[5-$k];
            
// Display color table cell
            
echo '<th'
                
.' style="background-color:#'.$color.'; color:#'.$colorinv.';">'
                
.'#'.$color
                
.'</th>'
                
;
        }
        
// End color table row
        
echo '</tr>';
    }
}
// End color table
echo '</table>';
?>
