resources - What difference between pclose and fclose in php -

i have code works pipes , files. @ end of operation function should close resource.

can close pipe resource fclose? seems not hard php track how close resource see 2 functions.

i create pipe popen function.

otherwise need method distinguish pipe , file resources.

get_resource_type returns "stream" both resources. 

or have implement expensive wrapper classes.

class pipestream {     public function __desctruct() { pclose($this->resource); } } class filestream {     public function __desctruct() { fclose($this->resource); } } 

read documentation of pclose() . used close process resource created popen() rather named pipe.

if working called, named pipes, objects stored in file system, use:

• posix_mkfifo() create them
• fopen() open them
• fclose() close them

as see, create fifo requires posix extension meaning not work on windows windows not support named pipes (or posix standard in general)
