Weather API (OpenWeather)
This API is free for 1000 calls per day, then has costs for subsequent calls. So, would need to create different accounts per project to avoid reaching the quota quick.
Create account
Generate API Key
Sample Codes:
<?php
$weather = get_transient( 'ff_weather' );
$location = 'Port Moresby';
if( !$weather ) {
$api_key = 'ENTER_API_KEY_HERE';
$data = file_get_contents_curl('https://api.weatherapi.com/v1/current.json?key='. $api_key .'&q='. urlencode($location));
if( $data ) {
$weather = json_decode($data);
set_transient('ff_weather', $weather, 3600); // refresh once every hour
}
}
if( !$weather ) return;
$temp = $weather->current->temp_c;
$condition = strtolower($weather->current->condition->text);
$type = 'cloudy';
if( strpos( $condition, 'rain' ) ) {
$type = 'rainy';
} else if( $condition == 'sunny' ) {
$type = 'sunny';
}
echo '<div class="weather cond_'. $type .'">';
echo '<span class="location">'. $location .'</span>';
echo '<span class="temp">'. $temp .'</span>';
echo '</div>';
