note 92025 added to features.file-upload

I've looked for an easy way to tell if there is a CSV extension. In the end I used: $filename = $_FILES['userfile']['name']; $filename = strtolower($filename) ; $returns = strrchr($filename,".csv"); if ($returns != ".csv"){ echo"fail"; } So this gets the file name converts it to lowercase finds the first occurance of .csv and then returns that and everything after it I then check that $returns only includes .csv If the file name had filename.csv.inc $returns would be .csv.inc and so it would fail. Only those with CSV extision pass this test. It'd be pretty easy to adjust the function to do multiple file types. I haven't tried it but something like this should work: $filename = $_FILES['userfile']['name']; $filename = strtolower($filename) ; $returns = strrchr($filename,"."); switch ($returns ) { case ".txt": echo "txt found"; break; case ".csv": echo "csv found"; break; case ".png: echo "png found"; break; default: echo "No valid file format found"; } ---- Server IP: 69.147.83.197 Probable Submitter: 86.14.190.32 ---- Manual Page -- http://www.php.net/manual/en/features.file-upload.php Edit -- https://master.php.net/note/edit/92025 Del: integrated -- https://master.php.net/note/delete/92025/integrated Del: useless -- https://master.php.net/note/delete/92025/useless Del: bad code -- https://master.php.net/note/delete/92025/bad+code Del: spam -- https://master.php.net/note/delete/92025/spam Del: non-english -- https://master.php.net/note/delete/92025/non-english Del: in docs -- https://master.php.net/note/delete/92025/in+docs Del: other reasons-- https://master.php.net/note/delete/92025 Reject -- https://master.php.net/note/reject/92025 Search -- https://master.php.net/manage/user-notes.php
