|

| 5 | * serverStats_Send will return an associative array with the options for you to use on your project. The

| 6 | * array contain the following keys:
|
|---|
| 7 | * InfoSent Boolean that tells if the information was sent through CURL or FOpen. If he information is
|
|---|
| 8 | * sent properly, InfoSent is set to true. Otherwise, it is set to false.
|
|---|
| 9 | * InfoQueryString String that contains the stats
|
|---|
| 10 | * InfoImage String with an image tag to send the stats
|
|---|
| 11 | * So if the info can't be sent through curl or fopen, you still have the options to put out an image (which
|
|---|
| 12 | * you just need to include in your template somewhere) or store the data in any other way you may find
|
|---|
| 13 | * convenient.
|
|---|
| 14 | *
|
|---|
| 15 | * Example:
|
|---|
| 16 | * <code>
|
|---|
| 17 | * require_once('server_stats.php');
|
|---|
| 18 | * $sending = serverStats_Send(0, '', 'NX 1.3.2', 'WE');
