copied!<p>I´m trying to place the result of a weather forecast function in a PHP return statement. To do this using concatenation I need to move a foreach loop up in the code and I just can´t get it to work. </p> <p>I´m trying to create a function like this: :</p> <pre><code>function getWeatherForecast($atts) { all variables go here; return 'concatenated output'; } </code></pre> <p>Here a link to the full script: <a href="http://pastebin.com/fcQpskmy" rel="nofollow">http://pastebin.com/fcQpskmy</a></p> <p>This is what I have now: </p> <pre><code>function getWeatherForecast($atts) { $xml = simplexml_load_file('http://www.google.com/ig/api?weather=barcelona'); $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"); /* The foreach loop should go here */ return '<h2>The weather today ' . $information[0]->city['data'] . '</h2>'; /* etc. etc. */ } </code></pre> <p>And this is the foreach loop that I need to place before the return statement: </p> <pre><code><?php foreach ($forecast_list as $forecast) : ?> <div> <img src="<?php echo 'http://www.google.com' . $forecast->icon['data']?>" alt="weather"?> <div><?php echo $forecast->day_of_week['data']; ?></div> <span> <?php echo $forecast->low['data'] ?>&deg; F – <?php echo $forecast->high['data'] ?>&deg; F, <?php echo $forecast->condition['data'] ?> </span> </div> <?php endforeach ?> </code></pre> <p>Thanks so much for your help!!</p>
