IntlDateFormatter::setLenient -- datefmt_set_lenient — Set the leniency of the parser
Object oriented style
Procedural style
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.
The formatter resource
Sets whether the parser is lenient or not, default is FALSE (strict).
如果成功则返回 TRUE，失败则返回 FALSE。
Example #1 datefmt_set_lenient() example
<?php
$fmt = datefmt_create( "en_US" ,IntlDateFormatter::FULL,IntlDateFormatter::FULL,'America/Los_Angeles',IntlDateFormatter::GREGO
RIAN ,"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').Result is : " .datefmt_parse($fmt,"35/13/1971");
if( intl_get_error_code() !=0 ){
echo "Error_msg is : ".intl_get_error_message();
echo "Error_code is : ".intl_get_error_code();
}
datefmt_set_lenient($fmt,false);
echo "Now 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').Result is : " .datefmt_parse($fmt,"35/13/1971");
if( intl_get_error_code() !=0 ){
echo "Error_msg is : ".intl_get_error_message();
echo "Error_code is : ".intl_get_error_code();
}
?>
