foreach的用法？？

[110199]

<?
$arr = array("one","two","three");
foreach($arr as $value);
{
echo "value: $value<br>\n";
}
?>
这个小程序为什么只输出了一个"three",而我想让数组的内容都输出来，foreach不是起遍历数组的作用吗？我不知道哪错了？？

[bflovesnow]

<?
$arr = array("one","two","three");
foreach($arr as $key=>$value);
{
echo "key:".$key.";value: $value<br>";
}
?>

<?
$arr = array("one","two","three");
foreach($arr as $value); <=== 删去这里的“;”
{
echo "value: $value<br>\n";
}
?>

<?php

/* foreach example 1: value only */

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

foreach ($a as $v) {

print "Current value of \$a: $v.\n";

}

/* foreach example 2: value (with key printed for illustration) */

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

$i = 0;

/* for illustrative purposes only */

foreach($a as $v) {

print "\$a[$i] => $k.\n";

}

/* foreach example 3: key and value */

$a = array (

"one" => 1,

"two" => 2,

"three" => 3,

"seventeen" => 17

);

foreach($a as $k => $v) {

print "\$a[$k] => $v.\n";

}

?>

呵呵，唠叨说得对。你多了个；
foreach是取得下一个数组的值，可以遍历数组，如果指针已经在某一位上了，建议reset($array)来把指针指到第一个元素

[hxatc]

foreach之前不需要reset数组的，它是自动将指针指向第一个元素，并且foreach之后原数组的指针位置不变

哈哈，又学到一个函数，这个好像在我的手册里没有耶。

foreach( $array as $key => $val)
{
echo $val;
}
