I have 3 files I need to write to - and need to make sure I have a lock on
each, and take action if I can't get a lock. The code below works, but I
know it could be more efficient if I used a function instead of the
repetitive code. Still kind of green in php.... Any help in creating a
function to eliminate the repeated file lock tests is appreciated. Thanks
in advance!
//***** write to visdata *****
$got_it = false;
$timeout = 5;
$new_visitor =
$visdate."|".
$visip."|".
$visos."|".
$visbrow."|".
$visisp;
$fp = fopen($visdata,"a");
/////******* CODE BELOW IS REPEATED**********
while (($got_it === false) && ($timeout != 0))
{
if (flock($fp, LOCK_EX))
{
fwrite($fp, $new_visitor."\n");
flock($fp, LOCK_UN);
$got_it = true;
}
else
{
usleep(100000);
--$timeout;
}
}
//echo "<br>got_it = ".$got_it;
//if cd not get lock after 5 tries (.5 sec.) skip and record failure
if (!$got_it)
{
$fp=fopen('/home/clearpoi/public_html/viscount_files/viscount_fail', 'a');
fwrite($fp,date("M d Y h:i a",time() + $timeadjust)."\n");
exit;

fclose($fp);
