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

以下示例演示了使用相对格式的date_parse_from_format()函数−

<?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"));
?>

这将会产生以下输出−

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] =>
)
