问题 This question already has answers here : Regular Expression to match valid dates (15 answers) date formatting with/without Moment.js (4 answers) Closed 6 years ago .

Can some one change it to validate mm/dd/yyyy format? Regular Expression: ^(((0[1-9]|[12]\d|3[01])/(0[13578]|1[02])/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d

How to convert a “HH:MM:SS” string to seconds with PHP?

由 故事扮演 提交于 2019-11-28 03:47:43
问题 Is there a native way of doing "HH:MM:SS" to seconds with PHP 5.3 rather than doing a split on the colon's and multipling out each section the relevant number to calculate the seconds? For example in Python you can do : string time = "00:01:05"; double seconds = TimeSpan.Parse(time).TotalSeconds; 回答1: The quick way: echo strtotime('01:00:00') - strtotime('TODAY'); // 3600 回答2: This should do the trick: list($hours,$mins,$secs) = explode(':',$time); $seconds = mktime($hours,$mins,$secs) -

Convert this string to timestamp PHP [duplicate]

由 醉酒当歌 提交于 2019-11-27 14:23:47
This question already has an answer here: Convert one date format into another in PHP 15 answers I have this string: "13/10 15:00" and I would like to convert it to timestamp but when I do this: $timestamp = strtotime("13/10 15:00"); It returns an empty value. In your code strtotime() is attempting to convert 13/10 as the tenth day of the 13th month, which returns an error. If you want to parse a date string with a custom format, it's better to use DateTime::createFromFormat() instead: $dtime = DateTime::createFromFormat("d/m G:i", "13/10 15:00"); $timestamp = $dtime->getTimestamp();

converting gregorian to hijri date

由 偶尔善良 提交于 2019-11-27 12:53:55
I want to convert from Gregorian to Hijri(Islamic) date and I need a java class for this converting. I want to give it an Gregorian date in format of "yyyy/mm/dd" as string and it give me the Hijri date in the same format. can anyone help me? Jon Skeet Firstly, separate out the conversion part from the formatting/parsing part. You can deal with those easily later - and there are lots of questions on Stack Overflow about that. Personally I'd use Joda Time , which typically makes life much simpler. For example: import org.joda.time.Chronology; import org.joda.time.LocalDate; import org.joda.time
