示例
示例 #1 DateTimeImmutable::getLastErrors() example
<?php
try {
$date = new DateTimeImmutable('asdfasdf');
} catch (Exception $e) {
// For demonstration purposes only...
print_r(DateTimeImmutable::getLastErrors());
// The real object-oriented way to do this is
// echo $e->getMessage();
}
?>以上示例会输出：
Array
(
[warning_count] => 1
[warnings] => Array
(
[6] => Double timezone specification
)
[error_count] => 1
[errors] => Array
(
[0] => The timezone could not be found in the database
)
)
The indexes 6, and 0 in the example output refer to the character index in the string where the error occurred.

If you are curious as to when the internal array gets resetted (from https://onlinephp.io/c/3ee35):
<?php
$date0 = DateTimeImmutable::createFromFormat('!Y-m-d', '2020-31-31');
var_dump($date0->format('c')); // 2022-07-31T00:00:00+00:00
foreach(range(0,2) as $_)
// The internal error won't reset
var_dump( join(DateTimeImmutable::getLastErrors()['warnings']) ); // The parsed date was invalid
$date1 = DateTimeImmutable::createFromFormat('!Y-m-d', '2020-12-31');
var_dump($date1->format('c')); // 2020-12-31T00:00:00+00:00
// The internal error did reset
var_dump( empty(DateTimeImmutable::getLastErrors()['warnings']) ); // true
$date2 = DateTimeImmutable::createFromFormat('!Y-m-d', '2020-31-31');
var_dump( join(DateTimeImmutable::getLastErrors()['warnings']) ); // The parsed date was invalid
$date3 = new DateTimeImmutable('2023-12-31T00:00:00.000000Z');
// The internal error did reset
var_dump( empty(DateTimeImmutable::getLastErrors()['warnings']) ); // true
?>
Output:
string(25) "2022-07-31T00:00:00+00:00"
string(27) "The parsed date was invalid"
string(27) "The parsed date was invalid"
string(27) "The parsed date was invalid"
string(25) "2020-12-31T00:00:00+00:00"
bool(true)
string(27) "The parsed date was invalid"
