Hallo,

Ik maak gebruik van een socket class om bepaalde informatie van bestanden op een andere locatie uit te lezen. Dit resultaat verwerk ik dan weer met reguliere expressies. echter voegt iets in deze class om de zoveel regels de waarde 2000 toe aan het bestand. Het lijkt op een soort buffer issue, maar snap niet helemaal waar het vandaan komt.

Ik heb al bij regel: 380 geprobeerd de 2e variable van fgets te verhogen, maar dit heeft geen effect.

Via een logger functie heb ik het eea uitgelezen en komt de volgende regel daarin:
20121002 10:32:04 result: 179 : <a href="http://twitter.com/home?sta

20121002 10:32:04 result: 180 :2000

20121002 10:32:04 result: 181 :tus=Alles+over+

Hier onder de volledige class:

Dit komt volgens mij voor bij chunked HTTP Responses.
http://en.wikipedia.org/wiki/Chunked_transfer_encoding

Deze valt te herkennen door de HTTP header 'Transfer-Encoding:chunked', die inderdaad op de website staat die je vermeld.

De eerste lijn zal dus aangeven hoeveel tekens er staan in het volgende gedeelte.
Als daar dus 2000 staat, dan zal het volgende gedeelte 2000 tekens bevatten.
Na die 2000 tekens staat er dus een nieuw getal, dat aangeeft hoeveel tekens er in het volgende gedeelte zitten.

Je zal dus moeten testen in de headers of het om een volledig document, of een chunked document gaat. Als het om het chunked document gaat, zal je dus de code moeten aanpassen en enkel het aangegeven aantal tekens moeten lezen.

Thanks, daar lijkt het inderdaad op. Nu nog vinden hoe ik daar mee om moet gaan, maar weet nu waar ik moet zoeken.
