How Can I Efficiently Convert dd/mm/YYYY Dates Using PHP's strtotime()?

strtotime() Conversion of Dates in dd/mm/YYYY Format

The strtotime() function is a powerful tool for converting dates into timestamps. However, the documentation for this function does not fully cover all the supported date formats. Specifically, strtotime() struggles with dates in dd/mm/YYYY format.

To address this issue, a common workaround is to manually explode the date string using the explode() function. However, there is a more efficient solution:

$date = '25/05/2010';
$date = str_replace('/', '-', $date);
echo date('Y-m-d', strtotime($date));

This snippet of code converts the date from dd/mm/YYYY to YYYY-mm-dd by replacing the forward slashes (/) with hyphens (-) and then using strtotime() to convert the resulting string into a timestamp. Finally, the date is formatted using the Y-m-d format specifier.

The result is a properly formatted date:

2010-05-25

According to the strtotime() documentation, dates in the formats m/d/y or d-m-y are automatically interpreted based on the separator: a slash (/) indicates American m/d/y format, while a dash (-) or dot (.) indicates European d-m-y format.
