The index can be assigned automatically index always starts at 0

First Need to Create Indexed Arrays

Create Indexed Arrays:
There are two ways to create indexed arrays:

1.Indexed Arrays can be assigned automatically (index starts at 0).

$Fruits = array("Cherries", "Mango", "Grape","Blueberry");

2.Indexed Arrays can be assigned manually(index starts at 0).

$Fruits [0] = "Cherries";
$Fruits [1] = "Mango";
$Fruits [2] = "Grape";
$Fruits [3] = "Blueberry";

Example(1)

<?php

$Fruits=array("Cherries","Mango","Grape","Blueberry");
echo "I like ".$Fruits[0].",".$Fruits[1].",".$Fruits[2]." and ".$Fruits[3].".";

?>

We Can also Use Loop For an Indexed Arrays:
Print all the values of an indexed arrays through the for loop

Example(2)

<?php

$Fruits=array("Cherries","Mango","Grape","Blueberry");
$arraylength = count($Fruits);

for($i = 0; $i < $arraylength; $i++) {
echo $Fruits[$i];
echo "<br>";
}

?>
