<?php

$parsed_json = json_decode($json_string);

アップデート

$json_string =    file_get_contents("http://api.wunderground.com/api/7ec5f6510a4656df/geolookup/forecast/q/40121.json");
$parsed_json = json_decode($json_string, true);
$parsed_json = $parsed_json['forecast']['txt_forecast']['forecastday'];
//pr($parsed_json);

foreach($parsed_json as $key => $value)
{
   echo $value['period'] . '<br>';
   echo $value['icon'] . '<br>';
   // etc
}

結果：

json_decode()そのためには関数を使用する必要があります。

$myArray = json_decode($yourJSON, true);

これで、配列foreachからデータを取得するために使用できます。$myArray

foreach($myArray['forecast']['forecastday'] as $key => $value)
{
   echo $value['period'];
   echo $value['icon'];
   // etc
}

json を PHP オブジェクトに変換することもできます。

$myData = json_decode($yourJSON);

foreach($myData->forecast->forecastday as $day) {
   echo $day->period;
   echo $day->icon;
}

これで質問のコードを修正できると思います：

<?php
$json_string =    file_get_contents("http://api.wunderground.com/api/7ec5f6510a4656df/geolookup/forecast/q/40121.json");
$parsed_json = json_decode($json_string);
$forecast = $parsed_json->forecast->txt_forecast;
$temp = $forecast->date;
$title = $forecast->forecastday->title;
$for = $forecast->forecastday->fcttext;
echo "Current date is ${temp},  ${title}: ${for}\n";

foreach($forecast->forecastday as $value) {
   echo $value['period'];
   echo $value['icon'];
   // etc
}
?>
