note 105096 added to features.commandline.io-streams

The following code shows how to test for input on STDIN. In this case, we were looking for CSV data, so we use fgetcsv to read STDIN, if it creates an array, we assume CVS input on STDIN, if no array was created, we assume there's no input from STDIN, and look, later, to an argument with a CSV file name. Note, without the stream_set_blocking() call, fgetcsv() hangs on STDIN, awaiting input from the user, which isn't useful as we're looking for a piped file. If it isn't here already, it isn't going to be. <?php stream_set_blocking(STDIN, 0); $csv_ar = fgetcsv(STDIN); if (is_array($csv_ar)){ print "CVS on STDIN\n"; } else { print "Look to ARGV for CSV file name.\n"; } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 173.8.118.221 ---- Manual Page -- http://www.php.net/manual/en/features.commandline.io-streams.php Edit -- https://master.php.net/note/edit/105096 Del: integrated -- https://master.php.net/note/delete/105096/integrated Del: useless -- https://master.php.net/note/delete/105096/useless Del: bad code -- https://master.php.net/note/delete/105096/bad+code Del: spam -- https://master.php.net/note/delete/105096/spam Del: non-english -- https://master.php.net/note/delete/105096/non-english Del: in docs -- https://master.php.net/note/delete/105096/in+docs Del: other reasons-- https://master.php.net/note/delete/105096 Reject -- https://master.php.net/note/reject/105096 Search -- https://master.php.net/manage/user-notes.php
