Example #1 datefmt_is_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($fmt,false);
echo 'Now lenient of the formatter is : ';
if ($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 "\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();
}

$fmt->setLenient(FALSE);
echo 'Now lenient of the formatter is : ';
if ($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();
}

?>

The above example will output:

lenient of the formatter is : TRUE
Trying to do parse('35/13/1971').
Result is : -2147483
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
