PNCTL not enabled in php even after compiling

Question

I just compiled my PHP with --enable-pcntl, but when I try to access the process control functions in PHP, I get:

Fatal error: Call to undefined function pcntl_fork()

Am I missing something? My apache is not compiled with prefork. Is that required for this to work?

Full PHP compile flags:

'./configure' 
'--prefix=/usr/local/lib64/php' 
'--with-libdir=lib64' 
'--with-apxs2=/usr/local/lib64/apache2/bin/apxs' 
'--with-mysql' 
'--enable-xml' 
'--with-curl' 
'--with-gd' 
'--enable-soap' 
'--with-xmlrpc' 
'--with-mysqli' 
'--with-unixODBC=/usr/' 
'--with-pdo-mysql' 
'--with-oci8=shared,instantclient,/usr/lib/oracle/11.2/client64/lib' 
'--with-mcrypt' 
'--enable-mbstring' 
'--with-zlib=/usr' 
'--with-openssl' 
'--enable-sockets' 
'--with-mssql=/usr/local' 
'--enable-ftp' 
'--enable-zip' 
'--enable-pcntl' 

Apache modules:

core mod_so http_core event mod_authn_file mod_authn_core mod_authz_host mod_authz_groupfile mod_authz_user mod_authz_core mod_access_compat mod_auth_basic mod_reqtimeout mod_filter mod_mime mod_log_config mod_env mod_headers mod_setenvif mod_version mod_unixd mod_dav mod_status mod_autoindex mod_dav_fs mod_dir mod_alias mod_rewrite mod_php5 

EDIT: Maybe I wasn't clear enough. I will not be using pcntl function from the web server. I would like to reiterate, that none of my pcntl functions are working from the command line either. Any idea on that?

Make sure you don't have multiple copies of PHP, since they can be configured in different ways.
