多维数组的foreach

Question

我想循环一个多维数组，并不太确定这是如何完成的。

$array = array(array('product1'=>'url1')); 
$array[] = array('product2'=>'url2'); 
$array[] = array('product3'=>'url3'); 

foreach($array as $name=>$url) 
{ 
echo '<a href="'.$url.'">'.$name.'</a>'; 
} 

这返回， 通知：Array对字符串的转换在test.php的第15行

通知：Array对字符串的转换在test.php的第15行

注意：第15行test.php中的数组到字符串转换

我在这里错过了什么吗？

Answer 1

请不要使用$ array作为变量名..如果是这样的话，会好得多。

$products = array(
    array('product1' => 'url1'), 
    array('product2' => 'url2'), 
    array('product3' => 'url3') 
); 

拉动数据：

foreach($products as $ind){ 

    .... 

    foreach($ind as $name){ 
    .... 

    } 
} 

Answer 2

currentpage.php

//this is required array which you want to enter in session 
$array = array(
     "product1" => "url1", 
     "product2" => "url2", 
     "product3" => "url3" 
    ); 

session_start();//here we start a session 
$_SESSION['product_url']=$array;//here we pass required array to session 

//By the help of below code we check is session contain array 
//echo "<pre>"; 
//print_r($_SESSION); 

requiedpage.php

session_start();//here we start a session 
//finally display required data to reqired page... 
foreach($_SESSION['product_url'] as $key=>$value) 
{ 
    echo '<a href="'.$value.'">'.$key.'</a><br>'; 
} 

为多维数组： -

currentpage.php 
    //this is required multidimensional array which you want to enter in session 
     $array= array(
       "[0]"=>array("product1" => 'url1',"product2" => 'url2',"product3" => 'url3') 
      ); 
requieredpage.php 
     foreach($_SESSION['product_url'] as $key=>$value) 
     { 
      foreach($value as $k=>$v){ 
       echo '<a href="'.$v.'">'.$k.'</a><br>'; 
      }  
     } 

输出我得到： -

product1 
product2 
product3
