[PHP] randomly random
OK gang, to spew a single line from a file of fortune cookies, I want to read it and echo one line. While I found a 4 line code which gets it done, I thought there was a preexisting command to do exactly that. Any feedback on this? -- end Very Truly yours, - Kirk Bailey, Largo Florida kniht +-+ | BOX | +-+ think -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, but it can be done in one line: ?php echo array_rand(@file(@$filename), 1); # if you wanted to do a couple checks, you could do the following if ( is_file(@$filename) filesize($filename) 0 ) echo array_rand(file($filename), 1); ?

This method will eat memory unless you have a very small file. Personally I would use filesize to get the length of the file, fopen it, fseek to a random position, then track back to a newline and use fgets to get the line. Then fclose, obviously.
