IntlDateFormatter::localtime -- datefmt_localtime — Parse string to a field-based time value
DescriptionObject-oriented style
Parametersformatter
The formatter resource
string
string to convert to a time
offset
Position at which to start the parsing in $value (zero-based). If no error occurs before $value is consumed, $parse_pos will contain -1 otherwise it will contain the position at which parsing ended . If $parse_pos > strlen($value), the parse fails immediately.
Localtime compatible array of integers : contains 24 hour clock value in tm_hour field, or false on failure.
Example #1 datefmt_localtime() example
<?php
$fmt
= datefmt_create(
'en_US',
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
'America/Los_Angeles',
IntlDateFormatter::GREGORIAN
);
$arr = datefmt_localtime($fmt, 'Wednesday, December 31, 1969 at 4:00:00 PM Pacific Standard Time', $offset);
echo 'First parsed output is ';
if ($arr) {
foreach ($arr as $key => $value) {
echo "$key : $value , ";
}
}?>
Example #2 OO example
<?php
$fmt = new IntlDateFormatter(
'en_US',
IntlDateFormatter::FULL,
IntlDateFormatter::FULL,
'America/Los_Angeles',
IntlDateFormatter::GREGORIAN
);
$arr = $fmt->localtime('Wednesday, December 31, 1969 at 4:00:00 PM Pacific Standard Time', $offset);
echo 'First parsed output is ';
if ($arr) {
foreach ($arr as $key => $value) {
echo "$key : $value , ";
}
}?>
The above example will output:
First parsed output is tm_sec : 0 , tm_min : 0 , tm_hour : 16 , tm_year : 69 , tm_mday : 31 , tm_wday : 3 , tm_yday : 365 , tm_mon : 11 , tm_isdst : 0 ,Patanjali ¶

Learning lesson here: Never trust the PHP documentation. Test everything!
$position does not work as described, at least in PHP 7. After parsing without errors, it does not contain -1.
You can still use it to set the parsing start character position, but not necessarily whether any errors occurred.
To test for errors, replace my $nPosition test code in the other note with:
<?php
$bError = intl_is_failure(datefmt_get_error_code(oIDF));if(!$bError){
...
}else{
...
}

You can use datefmt_localtime to convert a user's time string, input using their locale's script, into standard numbers for checking, using a simple HTML input element.
This avoids using clunky HTML select elements formatted with hour and minute options in the locale's script to capture user input.
<?php
$sLocale = 'en-us'; $sLocale = 'ar-ye'; $oIDF = datefmt_create($sLocale, IntlDateFormatter::NONE, IntlDateFormatter::SHORT);$sTime = datefmt_format($oIDF, ['tm_hour'=>15, 'tm_min'=>25]);
$nPosition = 0;$aTime = datefmt_localtime($oIDF, $sTime, $nPosition);
if($nPosition = -1){
...
}else{
...
}
?>
