用PHP解析一个字符串

Question

我的字符串类似于以下格式:

$ string ="name = xxx&id = 11&name = yyy&id = 12&name = zzz&id = 13&name = aaa&id = 10";

我想分割字符串,如下所示:

$ str [0] ="name = xxx&id = 11";

$ str [1] ="name = yyy&id = 12";

$ str [2] ="name = zzz&id = 13";

$ str [3] ="name = aaa&id = 10";

我怎么能用PHP做到这一点？

Answer 1

试试这个:

$matches = array();
preg_match_all("/(name=[a-zA-Z0-9%_-]+&id=[0-9]+)/",$string,$matches);

$matches 现在是一个包含你想要的字符串的数组.

更新

function get_keys_and_values($string /* i.e. name=yyy&id=10 */) {
  $return = array();
  $key_values = split("&",$string);
  foreach ($key_values as $key_value) {
    $kv_split = split("=",$key_value);
    $return[$kv_split[0]] = urldecode($kv_split[1]);
  }
  return $return;
}
