PHP: Highlight every second row of table - php

Question

I use this code to create a HTML table
for ($x = 0; $x <= $requiredRows; $x++) {
echo "<tr>";
echo "<td>";
echo someArrayStuff($x);
echo "</td>";
echo "<td>";
echo $someArrayStuff[$x][arrayinfos];
echo "</td>";
echo "<td>";
echo $someArrayStuff[$x][arrayinfos];
echo "</td>";
echo "</tr>";
}
Now I want to highlight every second row with a background color, how can I do this with PHP? I don't want to define it in the CSS file.
Thanks for all your help, now it works with this code:
if($x%2 == 0) { echo "<tr bgcolor='#FFFFF'>"; } else { echo "<tr bgcolor='#FFFFF'>"; }

Answer 1

if($x%2 == 0) {
echo '<tr class="bg-highlight">';
} else {
echo "<tr>";
}
and define a css class:
.bg-highlight {
background-color: red;
}

Answer 2

You can use mod. $x%2 will check if its a even row. which will be alternate row. If its found as even row then a different background color is given.
for ($x = 0; $x <= $requiredRows; $x++) {
if($x%2 == 0) { //even
echo "<tr style="background-color: #FF0000">";
} else { // odd
echo "<tr>";
}
echo "<td>";
echo someArrayStuff($x);
echo "</td>";
echo "<td>";
echo $someArrayStuff[$x][arrayinfos];
echo "</td>";
echo "<td>";
echo $someArrayStuff[$x][arrayinfos];
echo "</td>";
echo "</tr>";
}

Answer 3

You can simply create a dynamic class which will alter as per your loop
$class = ($x%2 == 0) ? "highlight" : "";
echo "<tr class='$class'>";
Just create a class named
.highlight{
background-color: grey;
}

Answer 4

Or You can simply use this code in css for odd or even rows of table.
div:nth-child(even)
{
background-color: yellow;
}

Answer 5

for ($x = 0; $x <= $requiredRows; $x++) {
echo "<tr";
if ($x % 2 === 1) {echo " style=\"background-color: yourFavoriteColor;\"";}
echo ">";
