note 15358 added to function.flush

Here's a little utility function that wraps printf and forces IE to flush its buffer by making the output 256 bytes long (pads with spaces). <? // function: ubprintf ('unbuffered printf') // the C prototype of this function would be: // void ubprintf(const char *format, ...); function ubprintf() { $args = func_get_args(); eval("printf(\"% 256s\", sprintf(\"" . implode("\", \"", $args) . "\"));"); flush(); } // useage example ubprintf("Testing..."); sleep(2); for ($i = 1; $i <= 3; $i++) { ubprintf("%d...", $i); sleep(2); } ?> http://www.php.net/manual/en/function.flush.php
