note 92561 added to function.rand

Here's a simple function to generate a random date between a start date and an end date. It is inclusive of BOTH dates - so using dates 2009-04-01 and 2009-04-03 would generate a random date that could be 2009-04-01, 2009-04-02 or 2009-04-03. It won't work if the end date is prior to the start date and if you use a non-existant date (eg 2009-02-30) it defaults to 1970-01-01 the longer version: <?php function makeRandomDateInclusive($startDate,$endDate){ $days = round((strtotime($endDate) - strtotime($startDate)) / (60 * 60 * 24)); $n = rand(0,$days); return date("Y-m-d",strtotime("$startDate + $n days")); } ?> and the one-line version for compactness freaks: <?php function makeRandomDateInclusive($startDate,$endDate){ return date("Y-m-d",strtotime("$startDate + ".rand(0,round((strtotime($endDate) - strtotime($startDate)) / (60 * 60 * 24)))." days")); } ?> it is called like this <?php echo makeRandomDateInclusive('2009-04-01','2009-04-03'); ?> Hope this is of some use to someone ---- Server IP: 64.71.164.2 Probable Submitter: 78.114.12.99 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/92561 Del: integrated -- https://master.php.net/note/delete/92561/integrated Del: useless -- https://master.php.net/note/delete/92561/useless Del: bad code -- https://master.php.net/note/delete/92561/bad+code Del: spam -- https://master.php.net/note/delete/92561/spam Del: non-english -- https://master.php.net/note/delete/92561/non-english Del: in docs -- https://master.php.net/note/delete/92561/in+docs Del: other reasons-- https://master.php.net/note/delete/92561 Reject -- https://master.php.net/note/reject/92561 Search -- https://master.php.net/manage/user-notes.php
