$str = '[{"actcode":"Auck4","actname":"Sky Tower","date":"","time":"","timeduration":"","adult":"0","adultprice":"28","child":"0","childprice":"0","description":"Discover the best of Auckland in half a day.

我試過下面的代碼

$array = json_decode($str,true);
echo print_r($array);

這個也是

$str1 = trim($str);
$array = json_decode($str1,true);
echo print_r($array);

但字符串 si 顯示為空白

Answer 1

試試這個。

$string = mysql_real_escape_string($str);
$findsym = array('\r', '\n');
$removesym = array("", "");
$strdone = stripslashes(str_replace($findsym,$removesym,strip_tags($string)));
$jsonarray = json_decode($strdone,true);
echo "<pre>"; echo print_r($jsonarray);
