 $arr = (array) json_decode($json,true);
 echo &#39;当前日期是：&#39;. $arr[&#39;report&#39;][&#39;date&#39;];
echo "<br/>";
echo '<pre class="brush:php;toolbar:false">';
 print_r($arr);
echo '
';     foreach($arr as $arrvalue)  {  foreach($arrvalue as $key=>$value)  {   echo "[$key] = $value 
";  }  } echo "
"; ?>

<!DOCTYPE html>
<html>
<body>
<?php
$file_exists = file_exists("json.txt");
if( $file_exists ){
 $myfile = fopen("json.txt", "r") or die("");
 $content = fread($myfile,filesize("json.txt"));
 fclose($myfile);
 echo $content;
 echo "<br/>";
 $arr=(array)json_decode($content,true);
 echo $arr['CSS'];
 echo "<br/>";
 echo $arr['AJAX'];
}
?>
 
</body>
