示例

以下示例演示了 date_parse_from_format() 函数的用法 -

<?php
   //Creating a DateTime object
   $date = "25-Mar-1989";
   $format = "d-M-Y";
   $res = date_parse_from_format($format, $date);
   print_r($res);
?>

这将产生以下结果 -

Array
(
    [year] => 1989
    [month] => 3
    [day] => 25
    [hour] =>
    [minute] =>
    [second] =>
    [fraction] =>
    [warning_count] => 0
    [warnings] => Array
        (
        )

    [error_count] => 0
    [errors] => Array
        (
        )

    [is_localtime] =>
)

示例

让我们看看解析日期的不同格式 -

<?php
   $res1 = date_parse_from_format("j.n.Y", "25.8.2014");
   print_r($res1);
   
   $res2 = date_parse_from_format("y-d-m", "2014-25-8");
   print_r($res2);
   
   $res3 = date_parse_from_format("n/j/y", "8/25/2014");
   print_r($res3);
   
   $res4 = date_parse_from_format("D.M.Y", "25.8.2014");
   print_r($res4);
   
   $res5 = date_parse_from_format("H/i/s", "12/32/25");
   print_r($res5);
?>

这将产生以下结果 -

示例

以下示例演示了带相对格式的 date_parse_from_format() -

<?php
   print_r(date_parse_from_format("Y-m-d", "2009-18-18-+52 week +25 hour"));
   print("\n");
   print_r(date_parse_from_format("Y-m-d", "1990-06-06 +52 week +25 hour"));
?>

这将产生以下输出 -

Array
(
    [year] => 2009
    [month] => 18
    [day] => 18
    [hour] =>
    [minute] =>
    [second] =>
    [fraction] =>
    [warning_count] => 1
    [warnings] => Array
        (
            [10] => The parsed date was invalid
        )

    [error_count] => 1
    [errors] => Array
        (
            [10] => Trailing data
        )

    [is_localtime] =>
)

Array

    [year] => 1990
    [month] => 6
    [day] => 6
    [hour] =>
    [minute] =>
    [second] =>
    [fraction] =>
    [warning_count] => 0
    [warnings] => Array
        (
        )

    [error_count] => 1
    [errors] => Array
        (
            [10] => Trailing data
        )

    [is_localtime] =>
)
