A simple example of color rotation, using the ternary operator, so that the program concise.
We have seen on the site that some table cell background color is interlaced, in fact, with a small section of the code below can be implemented: $color = (($coloralter + +%2)? "E0e0e0": "E8e8e8"), that is, by adding the variable sum and 2, using the ternary operator to obtain two different color values.
Examples are as follows:
<title>test</title>
<meta http-equiv= "Content-type" content= "text/html; charset=gb2312 ">

<body bgcolor= "#FFFFFF" >
<table width= "750" border= "0" cellspacing= "1" cellpadding= "1" >

<?php
For ($i =0 $i <5; $i + +) {
$color = (($coloralternator + +%2)? "E0e0e0": "ff6666");
echo "<tr bgcolor= '". $color. "' ><td> everyone good </td></tr> ";
}
?>
</table>
</body>
