note 78015 added to function.move-uploaded-file

If you are handling a file upload with move_uploaded_file and you want to get the file extension, I've seen examples using 'explode()', but you may run into problems if the file uses a period in the name. For example, if the uploaded file name is "this.video.file.mpg" and if you do an explode(), you'll get an array of 4 different values. To be safe, do a substr_count() ahead of the explode(), like this: $uploadedFileName = $_FILES['videoFile']['name'] ; $periodNum = substr_count($uploadedFileName, '.') ; $uploadedExplode = explode('.', $uploadedFileName) ; $fileExtension = $uploadedExplode[$periodNum] ; ---- Server IP: 69.147.83.197 Probable Submitter: 76.188.114.22 ---- Manual Page -- http://www.php.net/manual/en/function.move-uploaded-file.php Edit -- https://master.php.net/note/edit/78015 Del: integrated -- https://master.php.net/note/delete/78015/integrated Del: useless -- https://master.php.net/note/delete/78015/useless Del: bad code -- https://master.php.net/note/delete/78015/bad+code Del: spam -- https://master.php.net/note/delete/78015/spam Del: non-english -- https://master.php.net/note/delete/78015/non-english Del: in docs -- https://master.php.net/note/delete/78015/in+docs Del: other reasons-- https://master.php.net/note/delete/78015 Reject -- https://master.php.net/note/reject/78015 Search -- https://master.php.net/manage/user-notes.php
