Array With Numeric Index

  • Array with numeric index

    Or

    $suku[0] = ”Jawa”;

    $suku[1] = ”Sunda”;

    $suku[2] = ”Batak”;

    $suku[3] = ”Minang”;


Associative Array

  • Array with index based on current name

  • Example :

    $suku = array(“satu” => “Jawa”, “dua” => “Sunda”, “tiga” => “Batak”, “emapat” => “Minang”);


Array Manipulation

  • Adding Array (Push)

  • Merge Array

  • Deletion Array

  • Sorting Array


Adding Array (Push)

  • Used to adding array data to existing array

  • PHP function : array_push()

    $suku = array(”Jawa”, “Sunda”, “Batak”);

    $suku_baru = array_pop($suku);

    $arr = array("zero","one", "two", "three", "four", "five", "six");

    array_splice($arr,3,2);
