ifx_connect -- Open Informix server connection
Description
int 
ifx_connect ( [string database [, string userid [, string password]]] )
 
     Returns a connection identifier on success, or FALSE on
     error.
    
 
     ifx_connect() establishes a connection to an
     Informix server.  All of the arguments are optional, and if
     they're missing, defaults are taken from values supplied in configuration file
     (ifx.default_host for the host (Informix libraries will use
     INFORMIXSERVER environment value if not defined),
     ifx.default_user for user, ifx.default_password for the password
     (none if not defined).
    
 
     In case a second call is made to
     ifx_connect() with the same arguments, no
     new link will be established, but instead, the link identifier of
     the already opened link will be returned.
    
 
     The link to the server will be closed as soon as the execution of
     the script ends, unless it's closed earlier by explicitly calling
     ifx_close().
    
     
| Example 1. Connect to a Informix database | 
<?php$conn_id = ifx_connect ("mydb@ol_srv1", "imyself", "mypassword");
 ?>
