Summary: A PHP “string to date” conversion example.
For a recent PHP calendar project I needed to convert a given string into a 'date' I could work with more easily. In short, given a string date like this:
I wanted to convert that to some type of PHP date data structure I could use to render a calendar.
PHP string to date source code
The following PHP code shows the two steps I used to convert a date string into a PHP date structure I could work with:
<?php // (1) returns a Unix timestamp, like 1304496000 $time = strtotime("2011/05/21"); // (2) getDate() returns an associative array containing the date // information of the timestamp, or the current local time if // no timestamp is given $date = getDate($time); print_r($date); ?>
When printed, the $date data structure (a hash) looks like this:
Array ( [seconds] => 0 [minutes] => 0 [hours] => 0 [mday] => 21 [wday] => 6 [mon] => 5 [year] => 2011 [yday] => 140 [weekday] => Saturday [month] => May  => 1305964800 )
That's not the most impressive date data structure I've ever seen, but it worked for my purposes. As you can see, I can at least get basic information about the current weekday, the month, and day of the week.
PHP date functions
Here are links to documentation pages for the PHP functions I used in this example:
In my PHP calendar program I also determine the "next month" using the PHP mktime function:
FWIW, the line of code I use to determine the next month looks like this:
$next_month = getDate(mktime(1, 1, 1, $date['mon'] + 1, $date["mday"], $date["year"];));
I hope this PHP "string to date" example has been helpful.
