转换为关联数组PHP

Question

If you have this data:

1=Books
1.1=Action & Adventure
1.2=Arts, Film & Photography
1.2.1=Architecture
1.2.2=Cinema & Broadcast
1.2.3=Dance

The number on the data is the index. How can you put it in associative array? I want to know an example of associative array with that data. Thanks

Answer 1

Can be done with explode() and foreach

Steps:

1) First explode the string with new line character .

2) Loo over it.

3) You will get individual row, explode() it with =.

4) You will get required key in 0 and value in 1.

5) Store it in array as key value pair. Done

$str = '1=Books
1.1=Action & Adventure
1.2=Arts, Film & Photography
1.2.1=Architecture
1.2.2=Cinema & Broadcast
1.2.3=Dance';
$arr = explode("
", $str);
$assoc = array();
if (! empty($arr)) {
 foreach ($arr as $k => $v) {
  $temp = explode('=', $v);
  $assoc[$temp[0]] = $temp[1];
 }
}
echo '<pre>';print_r($assoc);echo '</pre>';

Output:

Array
(
 [1] => Books
 [1.1] => Action & Adventure
 [1.2] => Arts, Film & Photography
 [1.2.1] => Architecture
 [1.2.2] => Cinema & Broadcast
 [1.2.3] => Dance
)
