Title: PHP Indexed Arrays - PHP Arrays

An array that uses an index number by default is known as a PHP indexed array. An index number that begins at zero is used to identify each element of an array. Objects, characters, and integers may all be stored in a PHP indexed array. A numeric array in PHP is sometimes referred to as an index array.

There are two ways to create indexed arrays:

First:

$size=array("XS","S","M","L","XL","XXL");

Second:

$size[0]="XS";  
$size[1]="S";  
$size[2]="M";  
$size[3]="L";  
$size[4]="XL";  
$size[5]="XXL";

Example of an index array:

<?php
$size = array("Small", "Medium", "Large");
echo "Available sizes are " . $size[0] . ", " . $size[1] . " and " . $size[2] . ".";
?>

Output will be:

Available sizes are Small, Medium and Large.

Loop Through an Indexed Array in PHP

To loop through and print all the values of an indexed array, you could use a for loop, something like this:

Example:

<!DOCTYPE html>
<html>
<body>

<?php
$numbers = array("One", "Two", "Three", "Four", "Five");
$array_length = count($numbers);

for($n = 0; $n < $array_length; $n++) {
  echo $numbers[$n];
  echo "<br>";
}
?>

</body>
</html>

Output:

One
Two
Three
Four
Five
