In order to use posix_getpid on Fedeora 11 and up you have to install php-process

# yum install php-process

You can also try using getmypid() instead.

Since upgrading fedora 10 to 12, I discovered that posix_getpid() disappeared and not compiled in by default, as it specifies here.

It turns out that it had been moved into package php-process.

Just do "yum install php-process", and all should be sweet again.

Hope this saves someone half an hour of research.

A fall back function:
<?php
function get_current_id() {
if(!
function_exists(posix_getpid()))
return
getmypid();

return
posix_getpid();
}
?>

You can use this code in windows or if you system has no posix support:

<?php
if (!function_exists('posix_getpid')) {
function
posix_getpid() {
return
getmypid();
}
}
