DateTimeImmutable::getLastErrors

(PHP 5 >= 5.5.0, PHP 7, PHP 8)

DateTimeImmutable::getLastErrors — Returns the warnings and errors

说明

public static DateTimeImmutable::getLastErrors(): array|false

Returns an array of warnings and errors found while parsing a date/time string.

参数

此函数没有参数。

返回值

Returns array containing info about warnings and errors, or false if there are neither warnings nor errors.

更新日志

版本	说明
8.2.0	Before PHP 8.2.0, this function did not return `false` when there were no warnings or errors. Instead, it would always return the documented array structure.

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"
bool(true)
