(PHP 7)
error_clear_last — Clear the most recent error
Clears the most recent errors, making it unable to be retrieved with error_get_last().
Example #1 An error_clear_last() example
<?php
var_dump(error_get_last());
error_clear_last();
var_dump(error_get_last());
@$a = $b;
var_dump(error_get_last());
error_clear_last();
var_dump(error_get_last());
?>
The above example will output something similar to:
NULL
NULL
array(4) {
  ["type"]=>
  int(8)
  ["message"]=>
  string(21) "Undefined variable: b"
  ["file"]=>
  string(9) "%s"
  ["line"]=>
  int(6)
}
NULL
