IntlDateFormatter::setLenient -- datefmt_set_lenient — Set the leniency of the parser

### 说明

面向对象风格

public IntlDateFormatter::setLenient(bool `$lenient`): void

过程化风格

datefmt_set_lenient(IntlDateFormatter `$formatter`, bool `$lenient`): void

Define if the parser is strict or lenient in interpreting inputs that do not match the pattern exactly. Enabling lenient parsing allows the parser to accept otherwise flawed date or time patterns, parsing as much as possible to obtain a value. Extra space, unrecognized tokens, or invalid values ("February 30th") are not accepted.

### 参数

`formatter`

  The formatter resource

`lenient`

  Sets whether the parser is lenient or not, default is `true` (lenient).

### 返回值

成功时返回 `true`， 或者在失败时返回 `false`。

### 示例

示例 #1 datefmt_set_lenient() example

`<?php
$fmt = datefmt_create(
'en_US',
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
'America/Los_Angeles',
IntlDateFormatter::GREGORIAN,
'dd/MM/yyyy'
);
echo 'lenient of the formatter is : ';
if ($fmt->isLenient()) {
echo 'TRUE';
} else {
echo 'FALSE';
}
datefmt_parse($fmt, '35/13/1971');
echo "\n Trying to do parse('35/13/1971').\nResult is : " . datefmt_parse($fmt, '35/13/1971');
if (intl_get_error_code() != 0) {
echo "\nError_msg is : " . intl_get_error_message();
echo "\nError_code is : " . intl_get_error_code();
}
datefmt_set_lenient($fmt, false);
echo "\nNow lenient of the formatter is : ";
if ($fmt->isLenient()) {
echo 'TRUE';
} else {
echo 'FALSE';
}
datefmt_parse($fmt, '35/13/1971');
echo "\nTrying to do parse('35/13/1971').\nResult is : " . datefmt_parse($fmt, '35/13/1971');
if (intl_get_error_code() != 0) {
echo "\nError_msg is : ".intl_get_error_message();
echo "\nError_code is : ".intl_get_error_code();
}
?>`

示例 #2 OO example

`<?php
$fmt = new IntlDateFormatter(
'en_US',
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
'America/Los_Angeles',
IntlDateFormatter::GREGORIAN,
'dd/MM/yyyy'
);
echo 'lenient of the formatter is : ';
if ($fmt->isLenient()) {
echo 'TRUE';
} else {
echo 'FALSE';
}
$fmt->parse('35/13/1971');
echo "\n Trying to do parse('35/13/1971').\nResult is : " . $fmt->parse('35/13/1971');
if (intl_get_error_code() != 0) {
echo "\nError_msg is : " . intl_get_error_message();
echo "\nError_code is : " . intl_get_error_code();
}
$fmt->setLenient(FALSE);
echo "\nNow lenient of the formatter is : ";
if ($fmt->isLenient()) {
echo 'TRUE';
} else {
echo 'FALSE';
}
$fmt->parse('35/13/1971');
echo "\n Trying to do parse('35/13/1971').\nResult is : " . $fmt->parse('35/13/1971');
if (intl_get_error_code() != 0) {
echo "\nError_msg is : " . intl_get_error_message();
echo "\nError_code is : " . intl_get_error_code();
}
?>`

以上示例会输出：

    lenient of the formatter is : TRUE
    Trying to do parse('35/13/1971').
    Result is : 66038400
    Now lenient of the formatter is : FALSE
    Trying to do parse('35/13/1971').
    Result is :
    Error_msg is : Date parsing failed: U_PARSE_ERROR
    Error_code is : 9
