proxy prob!em using simplexml_load_file in php

问题

could somebody help me with this issue? I need to know in php latitude and longitude from an address.

I was doing:

$address = urlencode('my address');

$lat_lng = simplexml_load_file("http://maps.google.com/maps/api/geocode/xml?address={$address}&sensor=false");

but I got this warning:

Message: simplexml_load_file() [function.simplexml-load-file]: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution

I think I need to configure the proxy so I changed in this way:

$address = urlencode('my address');

$ch = curl_init("http://maps.google.com/maps/api/geocode/xml?address={$address}&sensor=false");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_PROXY, 'my_proxy);

curl_setopt($ch, CURLOPT_PROXYPORT, 'my+port');

$lat_lng = simplexml_load_string(curl_exec($ch));

curl_close($ch);

It seems to be blocked when I call curl_exec.

回答1:

Try w/o proxy settings first, it is probably error in proxy configuration.

function curl($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_close ($ch);
    return curl_exec($ch);
}

$address = urlencode($address);
$data = curl("http://maps.google.com/maps/api/geocode/xml?address=$address&sensor=false"); 
$lat_lng = simplexml_load_string($data);

Check your code

curl_close ($ch); 

should be the last line inside the function
