popen -- Opens process file pointer
Description
int popen (string command, string mode)
Opens a pipe to a process executed by forking the command given by command.
Returns a file pointer identical to that returned by
fopen(), except that it is unidirectional (may only be used for reading or writing) and
must be closed with pclose(). This pointer may be used
with fgets(),
fgetss(), and fputs().
If an error occurs, returns FALSE.
$fp = popen ("/bin/ls", "r");
