Question

您好我想问一下，改变google weather api天气图标的最佳途径是什么，改变它的路径到mysite.com/images/weather而不是/ ig / images / weather。我在堆栈溢出中看到了一个同样问题，但我不知道如何在我的代码上实现它。

这是我的代码：

    <?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 } ?>

非常感谢你的帮助

Answer 1

也许使用php函数basename来提取图标文件的名称：

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

Answer 2

我建议您使用PHP函数preg_replace替换$forecast->icon中的部分网址。

Answer 3

希望这能帮助别人找到解决方案：

使用：str_replace !!

而不是写作：

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';}

...

等等

...

$forecast->icon['data']和$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

...
    ?>

从现在开始，您可以看到从现在开始使用新的$iconData和$iconData2，例如Ex：

 <?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 } ?>
