Multidimensional Arrays

A multidimensional array holds recursively-defined arrays of arrays of data items. Typically, these items are selected and accessed via a sequence of integer indices.

The program below creates an empty two-dimensional array called: $saaSacraments. This array is stores the category in the first entry of the subarray and the sacraments in the subsequent entries.

MultidimensionalArrays.php

<?php
  $saaSacraments = array(
    array("Initiation", "Baptism", "Confirmation", "Eucharist"),
    array("Healing", "Reconciliation", "Anointing of the Sick"),
    array("Service", "Holy Orders", "Matrimony")
  );

  // Loop over the entries of the array and print them
  foreach ($saaSacraments as $sCategory) {
    echo "The Sacraments of <b>".$sCategory[0]."</b> are<br />";
    $iCount = count($sCategory);
    for ($i = 1; $i < $iCount; ++$i) {
      echo "{$sCategory[$i]}<br />";
    }
    echo "<br />";
  }
?>
