You will often have the need to access data that resides on another server, whether you are writing an online RSS aggregator or doing screen scraping for a searching mechanism. Boste pogosto potrebujete dostop do podatkov, ki stalno prebiva na drugem strežniku, ali pišete na spletu zbiralnik RSS ali "Narediti zaslon strganje za iskanje mehanizma. PHP makes pulling this data into a string variable an extremely simple process. PHP omogoča vlečenje te podatke v spremenljivke niz izjemno preprost proces.

You can go with the really short method: Lahko greš z zares kratko metoda:

$url = “http://www.howtogeek.com”; $ url = "http://www.howtogeek.com";

$str = file_get_contents($url); $ str = file_get_contents ($ url);

The only problem with that method is that some web hosts have url access blocked in the file methods, for security reasons. Edini problem s to metodo je, da nekateri spletni gostitelji imajo blokiran dostop url v datoteki metod, zaradi varnostnih razlogov. You may be able to use this workaround method instead: Morda boste lahko uporabljali to rešitev metodo namesto:

 function get_url_contents($url){ Funkcija get_url_contents ($ url) ( 
         $crl = curl_init(); $ = CRL curl_init (); 
         $timeout = 5; $ timeout = 5; 
         curl_setopt ($crl, CURLOPT_URL,$url); curl_setopt ($ RLS, CURLOPT_URL, $ url); 
         curl_setopt ($crl, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ RLS, CURLOPT_RETURNTRANSFER, 1); 
         curl_setopt ($crl, CURLOPT_CONNECTTIMEOUT, $timeout); curl_setopt ($ RLS, CURLOPT_CONNECTTIMEOUT, $ timeout); 
         $ret = curl_exec($crl); $ ret = curl_exec ($ CRL); 
         curl_close($crl); curl_close ($ CRL); 
         return $ret; return $ ret; 
 } ) 

You should now have the contents of the website in a string variable. Zdaj bi morali imeti vsebino spletne strani v nizu spremenljivke. Note that this doesn't pull down the supporting files such as javascript or CSS. Upoštevajte, da to ne podirajo podporne datoteke, kot so javascript in CSS. You will have to further parse the page and retrieve those seperately if you need the whole thing. Imeli boste dodatno razčleniti stran in pridobivanje tistih ločeno, če boste potrebovali vso stvar.
