Resolved: How to clear browser cache when re-uploading image with same filename, in php?
posted by admin on June 18, 2016
I have a listing of items, that also contains an image thumbnail. Sometimes I need to change the thumbnail image, but keep the filename the same. Is there a way to force the browser to download the newly uploaded image, instead of grabbing one from the browser cache?

This is very pertinent when people update their avatars, which causes confusion for some users, who keep seeing their old avatar, until they clear the browser cache, or restart the browser.Read more

    Wiki: PHP strtotime() Functionwiki
    posted by admin on May 22, 2016
    Parse English textual datetimes into Unix timestamps:

    echo(strtotime("now") . "
    echo(strtotime("3 October 2005") . "
    echo(strtotime("+5 hours") . "
    echo(strtotime("+1 week") . "
    echo(strtotime("+1 week 3 days 7 hours 5 seconds") . "
    echo(strtotime("next Monday") . "
    echo(strtotime("last Sunday"));

    Definition and Usage
    The strtotime() function parses an English textual datetime into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 GMT).

    Note: If the year is specified in a two-digit format, values between 0-69 are mapped to 2000-2069 and values between 70-100 are mapped to 1970-2000.

    Note: Be aware of dates in the m/d/y or d-m-y formats; if the separator is a slash (/), then the American m/d/y is assumed. If the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed. To avoid potential errors, you should YYYY-MM-DD dates or date_create_from_format() when possible.



    Parameter Description
    time Required. Specifies a date/time string
    now Optional. Specifies the timestamp used as a base for the calculation of relative dates

    Technical Details
    Return Value: Returns a timestamp on success. FALSE on failure
    PHP Version: 4+
    Changelog: PHP 5.3.0: Now relative time formats such as this week, previous week, last week, and next week interprets a week period of Monday through Sunday, rather then a 7-day period relative to the current date/time
    PHP 5.3.0: Now 24:00 is a valid format
    PHP 5.2.7: In earlier versions, if requesting a given occurrence of a given weekday in a month where that weekday was the first day of the month it would incorrectly add one week to the returned timestamp. This has been corrected now
    PHP 5.1.0: Returns FALSE on failure (earlier versions returns -1), and issues E_STRICT and E_NOTICE time zone errors
    PHP 5.0.2: Now correctly computes "now" and other relative times from current time, not from today's midnight
    PHP 5.0.0: Allows microseconds (but they are ignored)Read more
