Logging
|
||
|
|
-------
|
||
|
|
|
||
|
|
PicoFeed log in memory the execution flow, if a feed doesn't work correctly it's easy to see what is wrong.
|
||
|
|
|
||
|
|
### Reading messages
|
||
|
|
|
||
|
|
```php
|
||
|
|
use PicoFeed\Logging\Logger;
|
||
|
|
|
||
|
|
// All messages are stored inside an Array
|
||
|
|
print_r(Logger::getMessages());
|
||
|
|
```
|
||
|
|
|
||
|
|
You will got an output like that:
|
||
|
|
|
||
|
|
```php
|
||
|
|
Array
|
||
|
|
(
|
||
|
|
[0] => Fetch URL: http://petitcodeur.fr/feed.xml
|
||
|
|
[1] => Etag:
|
||

|
....
|
||
|
|
)
|
||
|
|
```
|
||
|
|
|
||
|
|
### Remove messages
|
||
|
|
|
||
|
|
All messages are stored in memory, if you need to clear them just call the method `Logger::deleteMessages()`:
|
||
|
|
|
||
|
|
```php
|
||
|
|
Logger::deleteMessages();
|
||
|
|
```
|
||
|
|
|
||
|
|
