Finding the Last Day of the Month in PHP

To obtain the last day of any given month in PHP, we can leverage a combination of the date and strtotime functions. Here's how:

Answer:

The date function, when passed the "t" format specifier, combined with the timestamp generated by strtotime for a given date, provides the number of days in that month.

Example:

To retrieve the last day of November 2009:

$a_date = "2009-11-23";
echo date("Y-m-t", strtotime($a_date));

Output:

2009-11-30

Similarly, for December 2009:

$a_date = "2009-12-23";
echo date("Y-m-t", strtotime($a_date));

Output:

2009-12-31
