How to alternate between 2 colors using PHP
This could come in handy if you have a table with multiple rows and if you wish to alternate between 2 colors.
We’ll need to use the Modulus Arithmetic Operator for this (%). Modulus (%) gets the remainder after a division has been made between 2 numbers. eg. 3%2 = 1
Code Example:
<table border="0" cellpadding="2" cellspacing="4">
<?php
$rows = 10; //Number of rows
for($i=0;$i<$rows;$i++){ //Looping through rows
$a = $i % 2; //Modulus Calculation
if($a == 1){ //If remainder is one we select grey as the color
$color = "#3e3e3e";
}else{ //If there's no remainder the color will be white
$color = "#ffffff";
}
?>
<tr style="background-color:<?=$color?>"> //Applying the relevant color
<td>Color 1</td>
</tr>
<?php
}
?>
