php curl functions issue - php

Question

I am having troble on curl functions in my codes. My CURLINFO_HTTP_CODE always return 0 and when I use
curl_error($ch) it returns 'could not reach host'. My host is ispeech and it shouldn't have problems. Can anyone here help me out? Thanks a lot!
iSpeech.php
class iSpeechBase{
var $server;
var $parameters = array("device-type"=>"php-SDK-0.3");
function setParameter($parameter, $value){
if ($parameter == "server")
$this->server = $value;
else
$this->parameters["$parameter"] = $value;
}
function makeRequest(){
$ch = curl_init();
$url=$this->server . "/?" . http_build_query($this->parameters);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
ob_start();
echocurl_exec($ch);
$http_body = ob_get_contents();
ob_end_clean();
echo curl_getinfo($ch, CURLINFO_HTTP_CODE); //return 0
echo curl_error($ch); //return Could not reach host.
if (curl_getinfo($ch, CURLINFO_HTTP_CODE) != 200)
if ($this->parameters["action"] == "convert")
return array("error" => $http_body);
return $http_body;
}
}

$result = $SpeechSynthesizer->makeRequest();

So save faffing around with the ob buffer, you could replace
ob_start();
echocurl_exec($ch);
$http_body = ob_get_contents();
ob_end_clean();
with
$http_body = curl_exec($ch);
Also adds the space between echo and curl_exec missing from your example (although that should throw a fatal and stop execution - do you have your own error handler?)
