json多维字符串的Preg Please

Question

我有这样的字符串：

<?php
echo $str_is;
?>

结果：

[["id_is","'bG1saW50YXMgbWFoYWthbTMyMTI'"],["date_is","'2015-2-25'"]]

我需要得到这样的数组：

$thearray["id_is"]="'bG1saW50YXMgbWFoYWthbTMyMTI'"
$thearray["date_is"]="'2015-2-25'"

我试过使用（我是新手，使用代码preg_match）：

$thearray = preg_match('/[(w+)/],([(w+)/]/', $str_is, $matches);

Answer 1

这是一种方法：

$str_is = <<< EOS
[["id_is","'bG1saW50YXMgbWFoYWthbTMyMTI'"],["date_is","'2015-2-25'"]]
EOS;
// Convert the JSON string to an array
$array = json_decode($str_is, true);
// Loop the array adding to $thearray
foreach ($array as $pair) {
   // First element = key (e.g. "id_is")
   // Second element = value (e.g. "'bG1saW50YXMgbWFoYWthbTMyMTI'")
    $thearray[$pair[0]] = $pair[1];
}
echo $thearray['id_is'], PHP_EOL;
echo $thearray['date_is'], PHP_EOL;

输出：

'bG1saW50YXMgbWFoYWthbTMyMTI'
'2015-2-25'
