[snip] I have a problem. I have created a fifo file (under linux) and I m not able to append some line from a php script. There is not output error, php just is executing for ever ... How can I write a fifo file? [/snip] Please have a look here; http://www.php.net/file as a starting point for file operations. You can append to a file with the fopen() function... http://www.php.net/fopen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
