PHP Codeigniter解析数组（[0] => test2 [1] =>测试1）

Question

i need help about how to parsing this array in codeigniter

array ( [0] => test0 [1] => test1)

in the CodeIgniter user guide i found this:

    {blog_entries}
            <h5>{title}</h5>
            <p>{body}</p>
    {/blog_entries}

Thats works if the array is like:

$data = array(
    'blog_title'   => 'My Blog Title',
    'blog_heading' => 'My Blog Heading',
    'blog_entries' => array(
            array('title' => 'Title 1', 'body' => 'Body 1'),
            array('title' => 'Title 2', 'body' => 'Body 2'),
            array('title' => 'Title 3', 'body' => 'Body 3'),
            array('title' => 'Title 4', 'body' => 'Body 4'),
            array('title' => 'Title 5', 'body' => 'Body 5')
    ));

http://www.codeigniter.com/user_guide/libraries/parser.html?highlight=parsing

But I receive array like this from one API:

    $data = array(
    'blog_title'   => 'My Blog Title',
    'blog_heading' => 'My Blog Heading',
    'blog_entries' => array(
            array('0' => 'Title 1', 'body' => 'Body 1'),
            array('1' => 'Title 2', 'body' => 'Body 2'),
            array('2' => 'Title 3', 'body' => 'Body 3'),
            array('3' => 'Title 4', 'body' => 'Body 4'),
            array('4' => 'Title 5', 'body' => 'Body 5')
    ));

How i can parse it? or how i can transform numbers [0,1,2,3] to [title,title,title,title]

You can just do a simple remaping function:

$out = array();
foreach ($blog_entries as $index => $array) {
    $out[] = array('title' => $array[$index], 'body' => $array['body']);
}

Sample Output:

array(5) {
  [0]=>
  array(2) {
    ["title"]=>
    string(7) "Title 1"
    ["body"]=>
    string(6) "Body 1"
  }
  [1]=>
  array(2) {
    ["title"]=>
    string(7) "Title 2"
    ["body"]=>
    string(6) "Body 2"
  }
  [2]=>
  array(2) {
    ["title"]=>
    string(7) "Title 3"
    ["body"]=>
    string(6) "Body 3"
  }
  [3]=>
  array(2) {
    ["title"]=>
    string(7) "Title 4"
    ["body"]=>
    string(6) "Body 4"
  }
  [4]=>
  array(2) {
    ["title"]=>
    string(7) "Title 5"
    ["body"]=>
    string(6) "Body 5"
  }
}
