从字符串中的编号列表创建数组

Question

I have a plain string like this:

1 //here is a number defines phrase name
09/25/2013 //here is a date
<i>some text goes here</i> //and goes text

2
09/24/2013 
text goes on and on

4 //as you can see, the numbers can skip another
09/23/2013
heya i'm a text

I need to create array from this but the numbers that defines phrases must give me the date of that line and return the text when i called it. Like,

$line[4][date] should give me "09/23/2013"

Is that possible, if possible can you explain me how to do this?

Answer 1

$stringExample = "1 
09/25/2013 
<i>some text goes here</i> 

2
09/24/2013 
text goes on and on
and on and on

4 
09/23/2013
heya i'm a text";

$data = explode("

", $stringExample);

$line = array();

foreach ($data as $block) {

    list($id, $date, $text) = explode("
", $block, 3);

    $index = (int) $id;

    $line[$index] = array();

    $line[$index]["date"] = trim($date);

    $line[$index]["text"] = trim($text);

}

var_dump($line) should output:

array(3) {
  [1]=>
  array(2) {
    ["date"]=>
    string(10) "09/25/2013"
    ["text"]=>
    string(26) "<i>some text goes here</i>"
  }
  [2]=>
  array(2) {
    ["date"]=>
    string(10) "09/24/2013"
    ["text"]=>
    string(34) "text goes on and on
and on and on"
  }
  [4]=>
  array(2) {
    ["date"]=>
    string(10) "09/23/2013"
    ["text"]=>
    string(15) "heya i'm a text"
  }
}

You can test it here.
