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