# Troubleshooting
|
|
|
|
### Debug using the diagnose method
|
|
|
|
```php
|
|
$curl = new Curl();
|
|
$curl->get('https://www.example.com/');
|
|
$curl->diagnose(); // ← HERE
|
|
```
|
|
|
|
### Debug the entire curl instance
|
|
|
|
```php
|
|
$curl = new Curl();
|
|
$curl->get('https://www.example.com/');
|
|
var_dump($curl); // ← HERE
|
|
```
|
|
|
|
### Ensure you have the latest version of the library installed
|
|
|
|
```bash
|
|
$ cd php-curl-class/
|
|
$ composer update
|
|
$ composer info
|
|
```
|
|
Compare your version with latest release &label=) which is also listed on the [releases page](https://github.com/php-curl-class/php-curl-class/releases).
|
|
|
|
### Ensure php is using the latest version of curl
|
|
|
|
```bash
|
|
$ php -r 'var_dump(curl_version());'
|
|
```
|
|
|
|
Compare your version of curl with latest release &label=) which is also listed on [curl's releases page](https://github.com/curl/curl/releases).
|
|
|
|
### Turn on error reporting
|
|
|
|
```php
|
|
error_reporting(E_ALL);
|
|
```
|
|
|
|
### Print some information that may hint at the cause of failure
|
|
|
|
```php
|
|
error_reporting(E_ALL);
|
|
$curl = new Curl();
|
|
$curl->get('https://www.example.com/');
|
|
echo 'error: ' . $curl->error . "\n";
|
|
echo 'errorCode: ' . $curl->errorCode . "\n";
|
|
echo 'errorMessage: ' . $curl->errorMessage . "\n";
|
|
echo 'curlError: ' . $curl->error . "\n";
|
|
echo 'curlErrorCode: ' . $curl->errorCode . "\n";
|
|
echo 'curlErrorMessage: ' . $curl->errorMessage . "\n";
|
|
echo 'httpError: ' . $curl->httpError . "\n";
|
|
echo 'httpStatusCode: ' . $curl->httpStatusCode . "\n";
|
|
echo 'httpErrorMessage: ' . $curl->httpErrorMessage . "\n";
|
|
echo 'requestHeaders:' . "\n";
|
|
var_dump($curl->requestHeaders);
|
|
echo 'responseHeaders:' . "\n";
|
|
var_dump($curl->responseHeaders);
|
|
```
|
|
|
|
### Turn on verbose mode
|
|
|
|
```php
|
|
error_reporting(E_ALL);
|
|
$curl = new Curl();
|
|
$curl->verbose();
|
|
$curl->get('https://www.example.com/');
|
|
var_dump($curl);
|
|
```
|
|
|
|
### Compare request with and without the library
|
|
|
|
```php
|
|
error_reporting(E_ALL);
|
|
$curl = new Curl();
|
|
$curl->get('https://www.example.com/');
|
|
var_dump($curl);
|
|
```
|
|
|
|
```php
|
|
error_reporting(E_ALL);
|
|
$ch = curl_init();
|
|
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
|
|
curl_setopt($ch, CURLOPT_HEADER, false);
|
|
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
|
|
curl_setopt($ch, CURLOPT_URL, 'https://www.example.com/');
|
|
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
|
|
curl_setopt($ch, CURLOPT_HTTPGET, true);
|
|
$raw_response = curl_exec($ch);
|
|
$curl_error_code = curl_errno($ch);
|
|
$curl_error_message = curl_error($ch);
|
|
$http_status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
|
|
$request_headers = curl_getinfo($ch, CURLINFO_HEADER_OUT);
|
|
var_dump($http_status_code);
|
|
var_dump($curl_error_code);
|
|
var_dump($curl_error_message);
|
|
var_dump($request_headers);
|
|
var_dump($raw_response);
|
|
```
|
|
|
|
### Ensure you have the latest version of composer installed
|
|
|
|
```bash
|
|
$ composer self-update
|
|
$ composer --version
|
|
```
|
|
|
|
Compare your version of composer with latest release &label=) which is also listed on [composer's releases page](https://github.com/composer/composer/releases).
