Agreed. strtotime has some annoying flaws that aren't officially
documented. For an illustration, try the following code:
<?php
echo date('m/d/Y', strtotime('3/31/2006')) . " - Today\n";
echo date('m/d/Y', strtotime('-1 month', strtotime("3/31/2006"))) . " -
Last Month (expect: 2/??/2006)\n";
echo date('m/d/Y', strtotime('+1 month', strtotime("3/31/2006"))) . " -
Next Month (expect: 4/??/2006)\n";
?>
This example shows how strtotime's handling of months could really
screw up logic expecting it to work in a different way than it actually
does (I should know, I've learned it the hard way). Since there are 28
days in Feb, strtotime adds the 3 extra days (to 31) and ends up at
March 3rd, similar problem with April, which has 30 days, so the extra
1 puts it to May 1st.
I've only really had a problem with strtotime with months, though.
Most other time intervals seem to work as expected.
