I’m having a heck of a time trying to figure out what is going on. I have a block of code that is throwing some errors. Outside of the Warnings and Notices the code works fine and the arrays are not empty. But why I am getting those warnings and notices is bothersome. In my test environment I don’t get the errors however when put on a different server they pop right up. I am stumped as to why. The lines of code that are throwing the errors and the errors being thrown are as follows
$libTitle = explode($libYearRes[0], $value); Notice: Undefined offset: 0 Warning: explode(): Empty delimiter $sortLibYearRes = explode(' ', $libYearRes[0]); Notice: Undefined offset: 0 $libMovieRes = $sortLibYearRes[1]; Notice: Undefined offset: 1
The entire block of code is as follows with the problem lines denoted with a @ in them
function checkMovieLibrary($movieTitle,$movieLibrary){ foreach ($movieLibrary as $value) { preg_match('/(dddd)sddd*[Pp]/', $value, $libYearRes); $libTitle = @explode($libYearRes[0], $value); $libMovieTitle = rtrim($libTitle[0]); $sortLibYearRes = @explode(' ', $libYearRes[0]); //list($libMovieYear,$libMovieRes) = explode(' ', $libYearRes[0], 2); $libMovieYear = $sortLibYearRes[0]; $libMovieRes = @$sortLibYearRes[1]; preg_match('/(dddd)sddd*[Pp]/', $movieTitle, $newfileYearRes); $newFileTitle_array = explode($newfileYearRes[0], $movieTitle); $newFileTitle = rtrim($newFileTitle_array[0]); $sortFileYearRes = explode(' ', $newfileYearRes[0]); $newFileMovieYear = $sortFileYearRes[0]; $newFileMovieRes = $sortFileYearRes[1]; if(stripos($libMovieTitle.' '.$libMovieYear, $newFileTitle.' '.$newFileMovieYear) !== false){ $moviesList_array[] = array('OriginalFile' => $value, 'NewFile' => $movieTitle); return($moviesList_array); } } return false; } //$movieTitle = "10 Cloverfield Lane (2016) 1080p.mkv"; //This is an example of $movieTitle string //$movieLibrary = array('10 Cloverfield Lane (2016) 1080p.mkv','The Goonies (1985) 1080p.mp4'); this is an example of the $movieLibrary array $doesMovieExist = checkMovieLibrary($Movie,$movieLibrary); if(is_array($doesMovieExist) && $doesMovieExist !== false){ foreach($doesMovieExist as $fileKey => $fileValue) { $originalFile = $fileValue['OriginalFile']; $newFile = $fileValue['NewFile']; } //do some stuff here }

First of all dont use @ because it will bypass the error message. So user error_reporting(E_ALL)
till development phase.
Then you are getting undefined offset it means your array is empty of does not exist so put a condition to check if it exist then the explode should work. It must be like that :
if(!empty($libYearRes[0]) || isset($libYearRes[0])) { $libTitle = @explode($libYearRes[0], $value); }
