## Error handling

All SAMConnection methods that provide access to messaging operations return `FALSE` if an error occurred in processing the request. In addition the SAMConnection object has two properties, "errno" and "error", that provide respectively the error number and text description of the last error to occur on the connection.

Exemplo #1 Handling an error from a method that returns no result

`<?php
if (!$conn->commit()) {
// The commit failed!
echo "Commit failed ($conn->errno) $conn->error";
}
?>`

Exemplo #2 Handling an error from a method that returns a result

`<?php
$correlid = $conn->send('queue://send/test', $msg);
if (!$correlid) {
// The Send failed!
echo "Send failed ($conn->errno) $conn->error";
} else {
/* ... */
}
?>`
