问题描述
我一直在php 5.3开发。
但是我们的生产服务器是5.2.6。
我一直在使用
$ schedule = '31 / 03/2011 01:22 pm' // example input
if(empty($ schedule))
$ schedule = date('Y-m-d H:i:s');
else {
$ schedule = dateTime :: createFromFormat('d / m / Y h:i a',$ schedule);
$ schedule = $ schedule-> format('Y-m-d H:i:s');
}
echo $ schedule;
但是该功能在5.2中不可用
什么是最简单的方法来解决(没有PHP升级的机会)。
解决方案
只需包含下一个代码
函数DEFINE_date_create_from_format()
{
函数date_create_from_format($ dformat,$ dvalue)
{
$ schedule = $ dvalue;
$ schedule_format = str_replace(array('Y','m','d','H','i','a'),array('%Y','%m','% d','%I','%M','%p'),$ dformat);
//%Y,%m和%d对应于date()的Y m和d。
//%I对应于H,%M到i和%p到a
$ ugly = strptime($ schedule,$ schedule_format);
$ ymd = sprintf(
//这是一个格式字符串,需要六个总十进制
//参数,然后将它们的零填充到
// 4或2个字符,根据需要
'%04d-%02d-%02d%02d:%02d:%02d',
$ ugly ['tm_year'] + 1900,//这将是111 ,所以我们需要添加1900.
$ ugly ['tm_mon'] + 1,//这将是一个月减一个,所以我们添加一个
$ ugly ['tm_mday'],
$ ugly ['tm_hour'],
$ ugly ['tm_min'],
$ ugly ['tm_sec']
);
$ new_schedule = new DateTime($ ymd);
return $ new_schedule;
}
}
if(!function_exists(date_create_from_format))
DEFINE_date_create_from_format();
I have been developing on php 5.3.
However our production server is 5.2.6.
I have been using
$schedule = '31/03/2011 01:22 pm'; // example input
if (empty($schedule))
$schedule = date('Y-m-d H:i:s');
else {
$schedule = dateTime::createFromFormat('d/m/Y h:i a', $schedule);
$schedule = $schedule->format('Y-m-d H:i:s');
}
echo $schedule;
However that function is not available in 5.2
What is the easiest way to get around this (no chance of a php upgrade).
解决方案
just include the next code
function DEFINE_date_create_from_format()
{
function date_create_from_format( $dformat, $dvalue )
{
$schedule = $dvalue;
$schedule_format = str_replace(array('Y','m','d', 'H', 'i','a'),array('%Y','%m','%d', '%I', '%M', '%p' ) ,$dformat);
// %Y, %m and %d correspond to date()'s Y m and d.
// %I corresponds to H, %M to i and %p to a
$ugly = strptime($schedule, $schedule_format);
$ymd = sprintf(
// This is a format string that takes six total decimal
// arguments, then left-pads them with zeros to either
// 4 or 2 characters, as needed
'%04d-%02d-%02d %02d:%02d:%02d',
$ugly['tm_year'] + 1900, // This will be "111", so we need to add 1900.
$ugly['tm_mon'] + 1, // This will be the month minus one, so we add one.
$ugly['tm_mday'],
$ugly['tm_hour'],
$ugly['tm_min'],
$ugly['tm_sec']
);
$new_schedule = new DateTime($ymd);
return $new_schedule;
}
}
if( !function_exists("date_create_from_format") )
DEFINE_date_create_from_format();
