For this, you can use for loop along with some conditions.
The PHP code is as follows −
Example
<!DOCTYPE html>
<html>
<body>
<?php
$arrayList = [];
for ($counter = 0; $counter < 5; $counter++) {
($counter%2) ? ($arrayList[] = $counter) : ($arrayList[] = "Even");
}
for ($counter = 0; $counter < 5; $counter++) {
echo $arrayList[$counter]," ";
}
?>
</body>
</html>Output
Even 1 Even 3 Even
Above, for 0th index, the text “Even” is displayed and the same goes on for 2th and 4th index.
