在谷歌天氣api上更改天氣圖標

Question

嗨，我只想問問什麼是改變谷歌天氣api上的天氣圖標的最佳方式，將其路徑更改爲mysite.com/images/weather而不是/ ig/images/weather。我在堆棧溢出中看到了一個與此問題相同的問題，但我不知道如何在我的代碼中實現它。

這裏是我的代碼：

<?php 
$xml = simplexml_load_file('http://www.google.com/ig/api?weather=new-york'); 
$information = $xml->xpath("/xml_api_reply/weather/forecast_information"); 
$current = $xml->xpath("/xml_api_reply/weather/current_conditions"); 
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions"); 
?> 

<h1>New-York City Weather</h1> 
<div class="weather"> 
<img src="<?php echo 'http://www.google.com' . $current[0]->icon['data']?>" alt="weather" /> 
<div class="condition"><strong>Today</strong><br /> 
<?php echo $current[0]->temp_f['data'] ?>° F,<?php echo $current[0]->condition['data'] ?> 
</div> 
</div> 

<?php foreach ($forecast_list as $forecast) { ?> 

    <div class="weather"> 
     <img src="<?php echo 'http://www.google.com' . $forecast->icon['data']?>" alt="weather" /> 
     <div class="condition"> 
      <strong><?php echo $forecast->day_of_week['data']; ?></strong><br /> 
       <?php echo $forecast->low['data'] ?>° F - <?php echo $forecast->high['data'] ?>° F, 
      <?php echo $forecast->condition['data'] ?> 
     </div> 
    </div> 
<?php } ?> 

非常感謝你的幫助

Answer 1

我建議你塗使用PHP函數preg_replace代替你在$forecast->icon有URL的一部分。

Answer 2

好，希望這會幫助別人我找到了解決辦法：

使用：str_replace！

而是寫的：

if($forecast->icon['data'] == '/ig/images/weather/sunny.gif') {$forecast->icon['data'] =   'path/to/folder/sunny.png';} 
if($forecast->icon['data'] == '/ig/images/weather/mostly_sunny.gif') {$forecast->icon['data'] =  'path/to/folder/mostly_sunny.png';} 
if($forecast->icon['data'] == '/ig/images/weather/partly_cloudy.gif') {$forecast->icon['data'] = 'path/to/folder/partly_cloudy.png';} 
if($forecast->icon['data'] == '/ig/images/weather/mostly_cloudy.gif') {$forecast->icon['data'] = 'path/to/folder/mostly_cloudy.png';} 
if($forecast->icon['data'] == '/ig/images/weather/chance_of_storm.gif') {$forecast->icon['data'] = 'path/to/folder/chance_of_storm.png';} 

...

等

...

既爲$forecast->icon['data']和$current[0]->icon['data']

只需使用：

$iconData = str_replace("/ig/images/weather/", "path/to/folder/", $current[0]->icon['data']); 
$iconData = str_replace(".gif", ".png", $iconData); //if you use different image extension 

和

<?php foreach ($forecast_conditions as $forecast) : 
    // CUSTOM ICONS 

$iconData2 = str_replace("/ig/images/weather/", "path/to/folder/", $forecast->icon['data']); 
$iconData2 = str_replace(".gif", ".png", $iconData2);//if you use different image extension 

... 
    ?> 

正如現在你可以看到從現在開始使用新的$iconData和$iconData2從現在開始，像前：

<?php 
$xml = simplexml_load_file('http://www.google.com/ig/api?weather=new-york'); 
$information = $xml->xpath("/xml_api_reply/weather/forecast_information"); 
$current = $xml->xpath("/xml_api_reply/weather/current_conditions"); 
$forecast_list = $xml->xpath("/xml_api_reply/weather/forecast_conditions"); 
//ADDED: 
$iconData = str_replace("/ig/images/weather/", "path/to/file/", $current[0]->icon['data']); 
$iconData = str_replace(".gif", ".png", $iconData); 
?> 
<h1>New-York City Weather</h1> 
<div class="weather"> 
<img src="<?php echo 'http://www.google.com' . $current[0]->icon['data']?>" alt="weather" /> 
<div class="condition"><strong>Today</strong><br /> 
<?php echo $current[0]->temp_f['data'] ?>° F,<?php echo $iconData ?> 
</div> 
</div> 

<?php foreach ($forecast_list as $forecast) { 
//ADDED 
$iconData2 = str_replace("/ig/images/weather/", "path/to/file/", $forecast->icon['data']); 
$iconData2 = str_replace(".gif", ".png", $iconData2); 
?> 



    <div class="weather"> 
     <img src="<?php echo 'http://www.google.com' . $iconData2 ?>" alt="weather" /> 
     <div class="condition"> 
      <strong><?php echo $forecast->day_of_week['data']; ?></strong><br /> 
       <?php echo $forecast->low['data'] ?>° F - <?php echo $forecast->high['data'] ?>° F, 
      <?php echo $forecast->condition['data'] ?> 
     </div> 
    </div> 
<?php } ?> 

Answer 3

也許使用PHP函數basename提取圖標文件的名稱：

$iconData = '/my/new/path/' . basename($current[0]->icon['data']);
