php 字符串转数组

Question

[{dmID=2311,attentionDate=1317368188.262348,attentionDegree=272,attentionCount=16},{dmID=2312,attentionDate=1317368197.902157,attentionDegree=72,attentionCount=8},{dmID=2313,attentionDate=1317368223.751104,attentionDegree=42,attentionCount=6}]能不能将上面的字符串转为数组， dmID，attentionDate attentionDegree attentionCount为key谢谢

Answer 1

你这个是哪弄出来的 json?又不是json

Answer 2

$str = <<<TXT
[{dmID=2311,attentionDate=1317368188.262348,attentionDegree=272,attentionCount=16},
{dmID=2312,attentionDate=1317368197.902157,attentionDegree=72,attentionCount=8},
{dmID=2313,attentionDate=1317368223.751104,attentionDegree=42,attentionCount=6}]
TXT;
$str = preg_replace(array('/(\w+)=/', '/=([^,}]+)/'), array('"$1":', '"$1"'), $str);
echo '<pre>';var_dump(json_decode($str));
/**
输出结果：

  0 => 
    object(stdClass)[1]
      public 'dmID' => int 2311
      public 'attentionDate' => float 1317368188.2623
      public 'attentionDegree' => int 272
      public 'attentionCount' => int 16
  1 => 
    object(stdClass)[2]
      public 'dmID' => int 2312
      public 'attentionDate' => float 1317368197.9022
      public 'attentionDegree' => int 72
      public 'attentionCount' => int 8
  2 => 
    object(stdClass)[3]
      public 'dmID' => int 2313
      public 'attentionDate' => float 1317368223.7511
      public 'attentionDegree' => int 42
      public 'attentionCount' => int 6

Answer 3

//多加一步，转为array
$str = <<<TXT
[{dmID=2311,attentionDate=1317368188.262348,attentionDegree=272,attentionCount=16},
{dmID=2312,attentionDate=1317368197.902157,attentionDegree=72,attentionCount=8},
{dmID=2313,attentionDate=1317368223.751104,attentionDegree=42,attentionCount=6}]
TXT;
$str = preg_replace(array('/(\w+)=/', '/=([^,}]+)/'), array('"$1":', '"$1"'), $str);
$json = json_decode($str);
foreach($json as $k=>$j) {
    $json[$k] = (array)$j;
}
echo '<pre>';var_dump($json);
/**

  2 =>

Answer 4

要加一步干什么？
json_decode($str, true) 就是数组了
