Indexed Array/Numeric Array

A Numeric Array store each element with a numeric values.

  • PHP Index is represent by number which start with zero.We Can Store(number,string) in the php array
  • All PHP array elements are asign to an Index Number.

    • There are two ways to create indexed arrays:

    The index can be assigned automatically (index always starts at 0), like this:

    $cars = array("Volvo", "BMW", "Toyota");

    or the index can be assigned manually:

    $cars[0] = "Volvo";
    $cars[1] = "BMW";
    $cars[2] = "Toyota";

    The following example creates an indexed array named $cars, assigns three elements to it, and then prints a text containing the array values:

    Example

    <?php
    $cars = array("Volvo", "BMW", "Toyota");
    echo "I like " . $cars[0] . ", " . $cars[1] . " and " . $cars[2] . ".";
    ?>

    Loop Through an Indexed Array

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

    Example

    <?php
    $cars = array("Volvo", "BMW", "Toyota");
    $arrlength = count($cars);

    for($x = 0; $x < $arrlength; $x++) {
        echo $cars[$x];
        echo "<br>";
    }
    ?>

    Run Example>>


    To loop through and print all the values of an indexed array, you can also use a foreach loop, like this:

    Example

    <?php
    $cars = array("Volvo", "BMW", "Toyota");

    foreach($car as $value) {
        echo $value;
        echo "<br>";
    }
    ?>

    Run Example>>

    Over Write Value

    Example

    <?php
    $carname[0]="Zen";
    $carname[1]="Alto";
    $carname[2]="BMW";
    $carname[3]="Maruti";
    $carname[2]=" Honda City";//overwrite BMw with Honda City
    echo $carname[0]."<br/>";
    echo $carname[1]."<br/>";
    echo $carname[2]."<br/>";
    echo $carname[3]."<br/>";
    ?>
