stream_set_blocking
  Set blocking/non-blocking mode on a stream
  
 
  Description
  
   bool stream_set_blocking
    ( resource $stream
   , bool $mode
   )
  
  
   This function works for any stream that supports non-blocking mode
   (currently, regular files and socket streams).
  
  
 
  Parameters
  
   
    
     - 
stream
- 
      
       The stream.
       
- 
mode
- 
      
       If modeisFALSE, the given stream
       will be switched to non-blocking mode, and ifTRUE, it
       will be switched to blocking mode.  This affects calls like
       fgets and fread
       that read from the stream.  In non-blocking mode an
       fgets call will always return right away
       while in blocking mode it will wait for data to become available
       on the stream.
 
 
 
  Return Values
  
   Returns TRUE on success or FALSE on failure.

  Note: 
   
    This function was previously called as
    set_socket_blocking and later
    socket_set_blocking but this usage is deprecated.
