This example defines a function called divide() that divides two numbers and throws an exception if the denominator is zero. It then calls the function with a denominator of zero inside a try-catch block. If an exception is thrown, the stack trace is retrieved and printed using print_r(). This can be useful for debugging issues in the code where the exception was thrown.
The getTrace() function is a part of the PHP core library and does not belong to any specific package or library. private function _ErrorLocation(\Exception $e)
{
$trace = $e->GetTrace();
$frame = NULL;
// Find the first frame from non-PHPUnit code, which is where the error
// should have occurred.
foreach ($trace as $f) {
if (isset($f['file']) && strpos($f['file'], 'PHPUnit/Framework') === FALSE) {
$frame = $f;
break;
}
}
if (!$frame)
$frame = $trace[0];
return $frame['file'] . ':' . $frame['line'];
}
