PHP问题 - 如何用字符串创建数组？

Question

In my database, some field settings are serialized and stored. When I do this:

print_r(unserialized($r['settings']));

I'll get this:

Array ( 
[prefix] => 
[suffix] => 
[min] => 
[max] => 
[allowed_values] => 1|Common 2|Rare 3|Almost Extinct 
)

I'm trying to create an array based on the values for allowed_values like this:

Array (
[1] => Common
[2] => Rare
[3] => Almost Extinct
)

The problem is, when I use explode("|", $r['allowed_values']), I get:

Array(
[0] => 1
[1] => Common 2
[2] => Rare 3
[3] => Almost Extinct
)

Which, makes sense, but obviously not what I was hoping for... So, I'm just wondering if there's a simple way to do what I'm trying here? I thought about using explode multiple times, once for spaces, and once for pipes, but that won't work either because of the space in "Almost Extinct"...

Answer 1

try this:

 $tab=array();
 preg_match_all("/\s*(\d+)\|([^\d]+)/",$r['allowed_values'],$tab);
 print_r(array_combine($tab[1],$tab[2]));

this should make the trick :)
