PHP strtotime returning wrong results

Question

strtotime(\'3rd January,2010\') returns 1230993600 in GMT+5:30.

While according to this, unix timestamp 1230993600 is 3rd January,2009. So it\'s off

Answer 1

strtotime() is not infallible. It is a contextual parser that tries to convert English descriptions of a date into a timestamp. The format you are using appears to be unsuitable for proper parsing.

You can see the differences in the following examples:

echo strtotime('3rd January,2010')."
";
echo strtotime('3 January, 2010')."
";
echo strtotime('January 3rd, 2010')."
";
echo strtotime('January 3, 2010')."
";

results in:

1231042200
1231042200
1262505600
1262505600

The first two return a different timestamp than the last two. Of the formats, the last two are more semantically (English-wise) correct, and I would try to use them instead.

EDIT

As other posters have noted, the comma confuses the parser about the date portion due to the order of your date tokens.

echo strtotime('3rd January 2010')."
";

returns the correct timestamp for your format.
