When using a multithreaded server like apache with worker.c on Linux you can use follow lines:
<?php
function fprotect($key,
$file,
$content=FALSE,
$fopen_mode='w',
$chmod=0600,
$sem_mode=0600
)
{
$semaphor=sem_get($key,1,$sem_mode);
sem_acquire($semaphor);
if($content)
{
if($dat=fopen($file,$fopen_mode))
{
chmod($file,$chmod);
fputs($dat,$content);
fclose($dat);
}
else return(FALSE);
}
else return(file_get_contents($datei));
sem_release($semaphor);
return(TRUE);
}
?>
Also this should work instead of flock() using a non-multithreaded server on Linux.
