Indexed array-
Numeric arrays use number as access keys. These arrays can store numbers, strings and any object but their index will be represented by numbers. And array index by default start from zero.
Example-
In this example showing how to create and access numeric indexed array. In this example we have used array() function to create array. And here we have explain array index and array value.
<!DOCTYPE html>
<html>
<head>
<title>Numeric Index Array</title>
</head>
<body>
<?php
#Create array
$num = array('100','200','300','400','500','600','700','800');
#Access array
#Print Index
foreach ($num as $key => $value) {
echo "Array index is is ".$key."<br>";
}
#Print value
foreach ($num as $key => $value) {
echo "Array value is ".$value."<br>";
}
