range() : create array with same key and value?

Last updated on January 17, 2018

In my recent client project, I am writing filters on data with different categories and where I need to filter data with year also, I wanted to use range function there, but range function generates different keys(I want the keys to be the same as the value(year)). here is the trick

 $years = array_combine(range(2000,2014),range(2000,2014));
 print_r($years);
 //output :
/* Array
(
    [2000] => 2000
    [2001] => 2001
    [2002] => 2002
    [2003] => 2003
    [2004] => 2004
    [2005] => 2005
    [2006] => 2006
    [2007] => 2007
    [2008] => 2008
    [2009] => 2009
    [2010] => 2010
    [2011] => 2011
    [2012] => 2012
    [2013] => 2013
    [2014] => 2014
