Handling errors when using CURL?

[maexus]

Handling errors in general has been an area that I haven't focused on as much as I'd like but at this point, it's something I need. I have a script that connects to gmail and downloads the inbox xml file. What I would like to do is stop the script and display any error from CURL. For example, timeouts, wrong auth credentials, server down, ect...

 

Here is the script that runs:

 

<?php #gmail2sms v2.0 by Kylee Tilley <[email protected]>
header("Content-type: text/plain"); 
require_once("curl.class.php");

$cell_email = NULL;

?>

gmail2sms
by Kylee Tilley
[email protected]
http://kyleetilley.name/

--- LOG FILE START ---

========================================================================
Connecting to Gmail:
========================================================================

<?php
flush();
$ch = new curl();
$ch->set_url("https://mail.google.com/mail/feed/atom");
$ch->set_auth("username", "password");
$ch->debug(1);
$ch->set_store_results(1);
$ch->execute();
if(isset($ch->error)){
trigger_error("Couldn't connect to Gmail: {$ch->error}");
}else{
echo "Connection to Gmail secured";
}
flush();
?>


========================================================================
Inbox Output:
========================================================================

<?php echo $ch->get_results(); ?>

--- LOG FILE END ---

 

and my curl.class.php

 

<?php
class curl {

private $handle;
private $results;
private $information;
public $error;
private $cookie_jar;

public function __construct(){
	$this->handle = curl_init();
	$this->cookie_jar = tempnam('/tmp','cookie');
	#$this->_prebuild();
}

public function post($string){
	$this->set_opt(CURLOPT_POST, 1);
	$this->set_opt(CURLOPT_POSTFIELDS, $string);
}

public function execute(){
	$this->results = curl_exec($this->handle) or die(curl_error($this->handle));
	$this->check_error();
	$this->information = curl_getinfo($this->handle);
}

private function check_error(){
	if(curl_errno($this->handle)){
		$this->error = curl_error($this->handle);
	}
}

public function get_info($option = NULL){
	return (isset($option)) ? $this->information[$option] : $this->information;
}

public function get_results(){
	return $this->results;
}

public function set_opt($option, $value){
	return curl_setopt($this->handle, $option, $value);
}

	public function set_url($url){
		$this->set_opt(CURLOPT_URL, $url);
	}

	public function set_auth($username, $password){
		$this->set_opt(CURLOPT_USERPWD, "{$username}:{$password}");
	}

	public function debug($bool){
		$this->set_opt(CURLOPT_VERBOSE, $bool);
	}

	public function set_store_results($bool){
		$this->set_opt(CURLOPT_RETURNTRANSFER, $bool);
	}

	public function use_proxy($url, $port, $username = NULL, $password = NULL){
		$this->set_opt(CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
		$this->set_opt(CURLOPT_PROXY, "{$url}:{$port}");
		$this->set_opt(CURLOPT_SSL_VERIFYPEER, 0);
		if(isset($username) && isset($password)){
			$this->set_opt(CURLOPT_PROXYUSERPWD, "{$username}:{$password}");
		}
	}

function __destruct(){
	curl_close($this->handle);
	unset($this->cookie_jar);
}
}
?>

 

Now, I may be missing something but an error should cause $this->error to populate and show the error in the if/then statement in the script. I have a feeling I'm WAY off on how to handle this but for some reason I can't wrap my mind around it.

 

Again, with all my posts, I'm not looking for a solution, just a push in the right direction.
