<para>
Iniciuje proudov� spojen� v internetov� (AF_INET, za pou�it� TCP nebo
UDP) nebo unixov� (AF_UNIX) dom�n�. Pro internetovou dom�nu otev�e TCP
kan�l na stroj <parameter>hostname</parameter> na port
<parameter>port</parameter>. <parameter>hostname</parameter> v takov�m
p��pad� m��e b�t pln� ur�en� dom�nov� jm�no nebo IP adresa. Pro spojen�
UDP mus�te explicitn� specifikovat protokol p�ed�azen�m
'<literal>udp://</literal>' p�ed <parameter>hostname</parameter>.
V unixov� dom�n� se <parameter>hostname</parameter> pou�ije jako cesta
k socketu <parameter>port</parameter> se pak mus� nastavit na 0.
Nepovinn� parametr <parameter>timeout</parameter> se m��e pou��t
k nastaven� time-outu pro syst�mov� vol�n� connect.
</para>
<para>
Od PHP 4.3.0, pokud jste PHP zkompilovali s podporou OpenSSL, m��ete
p�ed <parameter>hostname</parameter> p�ed�adit
'<literal>ssl://</literal>' nebo '<literal>tls://</literal>' pro pou�it�
SSL nebo TSL spojen� na vzd�len� stroj p�es TCP/IP.

<function>fsockopen</function> vrac� deskriptor souboru, kter� lze
pou��t s jin�mi souborov�mi funkcemi (nap�.
<function>fgets</function>, <function>fgetss</function>,
<function>fputs</function>, <function>fclose</function> a
<function>feof</function>).
</para>
<para>
Pokud vol�n� sel�e, vrac� funkce &false;, a pokud jsou p��tomny nepovinn�
parametry <parameter>errno</parameter> a <parameter>errstr</parameter>,
budou nastaveny na aktu�ln� chybovou �rove� v syst�mov�m vol�n�
<literal>connect()</literal>. Je-li vr�cen� hodnota v
<parameter>errno</parameter> rovna <literal>0</literal> a funkce vr�tila
&false;, znamen� to, �e chyba nastala p�ed vol�n�m
<literal>connect()</literal>. Nej�ast�ji je to kv�li probl�mu p�i
inicializaci socketu. Uv�domte si, �e argumenty
<parameter>errno</parameter> a <parameter>errstr</parameter> se v�dy
p�ed�vaj� odkazem.
</para>
<para>
V z�vislosti na prost�ed� nemus� b�t k dispozici unixov� dom�na nebo
voliteln� parametr timeout.
</para>
<para>
Socket se implicitn� otev�e v blokuj�c�m re�imu. Do neblokuj�c�ho
re�imu ho m��ete p�epnout pou�it�m
<function>socket_set_blocking</function>.

<?php
$fp = fsockopen ("www.example.com", 80, $errno, $errstr, 30);
