belajar foreach beragam

<?php
$arr = array("one", "two", "three");reset($arr);
while (list(, $value) = each($arr)) {
    echo "Value: $value<br />\n";
}

foreach ($arr as $value) {
    echo "Value: $value<br />\n";
}?>

================================

sama juga, tapi ada key nya 

<?php
$arr = array("one", "two", "three");reset($arr);
while (list($key, $value) = each($arr)) {
    echo "Key: $key; Value: $value<br />\n";
}

foreach ($arr as $key => $value) {
    echo "Key: $key; Value: $value<br />\n";
}?>
========================================






<?php

echo "<br/>cuyyyy  1";
/* foreach example 1: value only */

$a = array(1, 2, 3, 17);

foreach ($a as $v) {
    echo "<pre>";
    echo "Current value of \$a: $v.\n";
    echo "</pre>";
}



echo "<br/>cuyyyy 2";
/* foreach example 2: value (with its manual access notation printed for illustration) */

$a = array(1, 2, 3, 17);

$i = 0; /* for illustrative purposes only */

foreach ($a as $v) {
      echo "<pre>";
    echo "\$a[$i] => $v.\n";
     echo "</pre>";
    $i++;
}




echo "<br/>cuyyyy 3";
/* foreach example 3: key and value */

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => 17
);

foreach ($a as $k => $v) {
      echo "<pre>";
    echo "\$a[$k] => $v.\n";
      echo "</pre>";
}

echo "<br/>cuyyyy 4";
echo "<br/>";

/* foreach example 4: multi-dimensional arrays */
$a = array();
$a[0][0] = "a";
$a[0][1] = "b";
$a[1][0] = "y";
$a[1][1] = "z";

foreach ($a as $v1) {
    foreach ($v1 as $v2) {
          // echo "<pre>";
        echo "$v2\n";
          // echo "/<pre>";
    }
}


echo "<br/>cuyyyy 5";
echo "<br/>";
/* foreach example 5: dynamic arrays */

foreach (array(1, 2, 3, 4, 5) as $v) {

      // echo "<pre>";
    echo "$v\n";
      // echo "</pre>";
}

?>
