<para>
|
|
<function>ifx_pconnect</function> acts very much like
|
|
<function>ifx_connect</function> with two major differences.
|
|
</para>
|
|
<para>
|
|
First, when connecting, the function would first try to find a
|
|
(persistent) link that's already open with the same host,
|
|
username and password. If one is found, an identifier for it
|
|
will be returned instead of opening a new connection.
|
|
</para>
|
|
<para>
|
|
Second, the connection to the SQL server will not be closed when
|
|
the execution of the script ends. Instead, the link will remain
|
|
open for future use (<function>ifx_close</function> will not
|
|
close links established by <function>ifx_pconnect</function>).
|
|
</para>
|
|
<para>
|
|
This type of links is therefore called 'persistent'.

All of the arguments are optional, and if they're missing, defaults are
|
|
taken from values supplied in &php.ini; (ifx.default_host for the host
|
|
(Informix libraries will use <envar>INFORMIXSERVER</envar> environment
|
|
value if not defined), ifx.default_user for user, ifx.default_password for
|
|
the password (none if not defined).
