You seem to be quite confused. First of all, a function like fdopen() which has never existed in any version of PHP, wouldn't read/write anything. In C that function will return a FILE pointer from a file descriptor. You would then use fread()/fwrite() to read and write from that FILE pointer. But PHP doesn't have file pointers nor file descriptors, so none of this applies to PHP. In PHP an open file is a resource just like an open database connection is a resource.
So, is your question really how to read and write to files? There are many ways to do that. The easiest is to just call file_get_contents()/file_put_contents(), but you can also use fopen()/fread()/fwrite() if you prefer that approach. -Rasmus On Fri, Apr 16, 2010 at 5:15 AM, Naga Kiran K <k.nagaki...@gmail.com> wrote: > Hi Rasmus, > > Thanks for reply. > The requirement I was looking for is to read/write given only the file > descriptor number. > > PHP-CGI binary is invoked by a webserver that runs in jail-directory and > doesn't have access to the file path directory. > So, it communicates with another daemon that opens a socket to that file > and in turn passes the file descriptor alone. > > Can you please suggest if there is any API in PHP that serves this > requirement [read/write to given file descriptor] > Please let me know if I need to provide more information. > > Thanks, > Naga Kiran > > > On Thu, Apr 15, 2010 at 7:33 PM, Rasmus Lerdorf <ras...@lerdorf.com>wrote: > >> On 04/15/2010 06:52 AM, Naga Kiran K wrote: >> > Hi, >> > >> > We are upgrading PHP from 5.2.3 to 5.3.2 and are facing few issues [like >> > unsupported functions...] >> > >> > In PHP 5.2.3, "fdopen" was used to read/write to a file descriptor >> > that's opened by another application. >> > >> > fdopen(<fileDescriptorId>,"rw"); //It worked fine with PHP 5.2.3 >> > >> > After PHP upgrade,its throwing "undefined reference to 'fdopen' >> function". >> > >> > Please suggest whats the replacement for this in PHP 5.2.3 or any >> > workaround. >> >> PHP has never had an fdopen() function.
