Question

我有以下数组

 Array ( [0] => Please enter address line 1 
          [1] => Please tell us your first name 
          [2] => Please tell us your last name 
          [3] => Please tell us your email 
          [4] => You must tell us one phone number 
          [5] => Please tell us second applicants title 
          [6] => Please tell us second applicants first name 
          [7] => Please tell us second applicants last name )

我循环遍历如下 foreach($error_hash as $value) { echo "error <li> $value <li/>"; }

令人讨厌的是我一直在拿空行

请输入地址第1行

错误

请告诉我们您的名字

错误

等.......

任何输入都会很棒

Answer 1

在'li'标签内嵌入'错误'，因此不会产生额外的输出。类似的东西：

echo "<li> error, $value </li>";

Answer 2

观看您的标记

<li/>

也许这会有所帮助：

</li>

Answer 3

我已经查过了。这是工作。

$a[0] = 'Please enter address line 1';
$a[1] = 'Please tell us your first name';
foreach ($a as $b) {
    echo $b;
}

为什么这个非常简单的数组迭代不起作用？
