php - Using cURL with wunderground api -

hey i'm having issues using curl (i can't use file_get_contents because web host won't allow it) access parts of wunderground weather api.

when use following code access info on weather conditions have no issues whatsoever:

<? $json_url = 'http://api.wunderground.com/api/b2b4a1ad0a889006/geolookup/conditions   /q/ia/cedar_rapids.json';    // json string request $json_string = '[http://api.wunderground.com/api/b2b4a1ad0a889006/geolookup/conditions /q/ia/cedar_rapids.json]';  // initializing curl $ch = curl_init( $json_url );  // configuring curl options $options = array( curlopt_returntransfer => true, );  // setting curl options curl_setopt_array( $ch, $options );  // getting results $result =  curl_exec($ch); // getting json result string  $parsed_json = json_decode($result);  $location = $parsed_json->{'location'}->{'city'};  $temp_f = $parsed_json->{'current_observation'}->{'temp_f'};  echo "current temperature in ${location} is: ${temp_f}\n"; ?> 

however, when make slight modifications in order data on high , low tides using following code nothing:

<? $json_url = 'http://api.wunderground.com/api/b2b4a1ad0a889006/tide/q/nj/wildwood.json';    // json string request $json_string = '[http://api.wunderground.com/api/b2b4a1ad0a889006/tide/q/nj/wildwood.json]';  // initializing curl $ch = curl_init( $json_url );  // configuring curl options $options = array( curlopt_returntransfer => true, );  // setting curl options curl_setopt_array( $ch, $options );  // getting results $result =  curl_exec($ch); // getting json result string  $tide_time = $parsed_json->{'tide'}->{'tidesummary'}->{'date'}->{'pretty'};  echo "high tide @ ${tide_time} "; ?> 

now know issue may i'm dealing array in second example i'm not sure how modify code. know record first low tide [3] , i've tried making following modification no luck.

$tide_time = $parsed_json->{'tide'}->{'tidesummary'}->[3]->{'date'}->{'pretty'};  echo "high tide @ ${tide_time} "; 

any appreciated!

the second parameter of json_decode allows decode json array instead of object. try turning on know you're dealing with:

$response = json_decode($result, true);

if fails maybe you're not using api correctly?
