Associative Arrays
<?php
$printer['R&B PRINTERS']= "Laserjet 2002";
$printer['Jackson Printers'] = "J2001Laserjet";
print_r($printer);
//result
array (
'R&B PRINTERS' => "Laserjet 2002",
'Jackson Printers' => "J2001Laserjet",
)
?>
|
with associative arrays, you can reference the items in an array by name rather than by number.
Multidimensional Arrays
<?php
$products = array(
'pens' => array(
'ball' => "Ball Point",
'hilite' => "Highlighters",
'marker' => "Markers"),
'misc' => array(
'tape' => "Sticky Tape",
'glue' => "Adhesives",
'clips' => "Paperclips"
)
);

Assignment using the array Keyword
`<?php
$p1 = array("China", "Russia", "Austria", "Turkey");
$p2 = array
(
'china' => "Beijing",
'Russia' => "Moscow" ,
'Austria' => "Vienna",
'Turkey' => "Ankara"
);
|
The for..each as loop
<?php
$paper = array("Copier", "Inkjet", "Laser", "Photo");
$j = 0;
foreach($paper as $item)
{
echo "$j: $item<br>";
++$j;
}
?>
