this question has answer here:

• nested if's not working in php either nothing or goes end of code 2 answers

the second condition date working fine, first condition echoing w, whether input wrong or correct. why ?

$file_name='nzl-00-2015';  list($name_loc, $name_date) = explode('-', $file_name, 2); if($name_loc != "cal" || "flp" || "arz") {     echo "w";}    else  {     echo "g";}  $d = datetime::createfromformat('m-y', $name_date); if($d && $d->format('m-y') != $name_date){     echo "wrong";}    else  {     echo "good";}

because "flp" , "arz" truthy values, if statement true. think mean:

if($name_loc != "cal" && $name_loc != "flp" && $name_loc != "arz") { 

or, have way - if $name_loc isn't found in array of values:

if(!in_array($name_loc, array('cal', 'flp', 'arz'))){
