IntlDateFormatter::localtime -- datefmt_localtime — Parse string to a field-based time value
Описание
Объектно-ориентированный стиль
$value
[, int &$position
] )Процедурный стиль
Converts string $value to a field-based time value ( an array of various fields), starting at $parse_pos and consuming as much of the input value as possible.
Список параметров
-
fmt -
The formatter resource
-
value -
string to convert to a time
-
position -
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.
Возвращаемые значения
Localtime compatible array of integers : contains 24 hour clock value in tm_hour field

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
// Specify locale of user
$sLocale = 'en-us'; // US English user
$sLocale = 'ar-ye'; // Yemen Arab user
// Create a date formatter for the user's locale
$oIDF = datefmt_create($sLocale, IntlDateFormatter::NONE, IntlDateFormatter::SHORT);
// Simulate a user's time input string
$sTime = datefmt_format($oIDF, ['tm_hour'=>15, 'tm_min'=>25]);
// For a US English user, $sTime = '3:25 PM'
// For a Yemen Arab user, $sTime = '٣:٢٥ م'
// Specify datefmt_locale parsing start at the beginning of the user input
$nPosition = 0;
// Convert input time string to array of standard numeric values, as per localtime() output (function.localtime)
$aTime = datefmt_localtime($oIDF, $sTime, $nPosition);
// If no errors, $nPosition set to -1 after parsing, else character position of error
// If valid string
if($nPosition = -1){
// Use 'tm_hour' and 'tm_min' from the $aTime array for checking against other time values
...
}else{
// Invalid string
...
}
?>
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
// Check if errors
$bError = intl_is_failure(datefmt_get_error_code(oIDF));
// If no error
if(!$bError){
// Use 'tm_hour' and 'tm_min' from the $aTime array for checking against other time values
...
}else{
// Invalid string
...
}
?>
