谁能修复我的 foreach 循环？
我有这样的代码
<?php
$array = array('http://www.google.com', 'http://www.facebook.com', 'http://www.twitter.com');
foreach ( $array as $website );
{
echo "<pre>";
echo "Hi $website\n";
echo "Hello $website\n";
echo "Welcome $website\n";
echo "</pre>";
}
?>
我的输出看起来像这样
Hi http://www.twitter.com
Hello http://www.twitter.com
Welcome http://www.twitter.com
我的意思是我的代码仅打印最后一个数组值。但我想要这样的输出。
Hi http://www.google.com
Hello http://www.google.com
Welcome http://www.google.com
Hi http://www.facebook.com
Hello http://www.facebook.com
Welcome http://www.facebook.com
Hi http://www.twitter.com
Hello http://www.twitter.com
Welcome http://www.twitter.com
谁能告诉我为什么它只打印最后一个值？ 谢谢

删除分号：

有一个额外的

$website位于最后一项时，您执行一个带有 echo 的块。删除
;就可以了This line

$websiteis on the last item, you perform a block with an echo.remove the

Remove the semicolon from this line:
foreach 循环末尾有一个分号 (;)。这意味着 { } 块不是在循环内部，而是在 foreach 循环完成迭代后执行一次。
只需删除 ;从最后。
You have a semicolon (;) at the end of your foreach loop. This means that instead of the { } block being inside the loop, it just executes once, after the foreach loop finished iterating.
Just drop the ; from the end.
foreach语句末尾有一个分号。删除是，您将拥有您需要的功能You have a semicolon at the end of your
foreachstatement. Remove is and you will have the functionality you require
