IntlDateFormatter::setLenient

datefmt_set_lenient

(PHP 5 >= 5.3.0, PECL intl >= 1.0.0)

IntlDateFormatter::setLenient -- datefmt_set_lenientSet the leniency of the parser

说明

面向对象风格

public bool IntlDateFormatter::setLenient ( bool $lenient )

过程化风格

bool datefmt_set_lenient ( IntlDateFormatter $fmt , bool $lenient )

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

fmt

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

范例

Example #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 ();
}

?>

Example #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 ();
}

?>

以上例程会输出:

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
