stream_set_blocking

Set blocking/non-blocking mode on a stream

Syntax

stream_set_blocking ( resource $stream , bool $mode ) : bool

Parameters

stream

The stream.

mode

If mode is FALSE, the given stream will be switched to non-blocking mode, and if TRUE, 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

Returns TRUE on success or FALSE on failure.

Examples

1 · stream mode · false

<?

$filename = "https://osbo.com";

$stream = fopen($filename, "rb");

    $mode = false;

    $return = stream_set_blocking($stream, $mode);
    
    var_export($return);

    $length = 1024;

    while (!feof($stream))
    {
        fgets($stream, $length);
    }

fclose($stream);

?>
true

2 · stream mode · true

<?

$filename = "https://osbo.com";

$stream = fopen($filename, "rb");

    $mode = true;

    $return = stream_set_blocking($stream, $mode);
    
    var_export($return);

    $length = 1024;

    while (!feof($stream))
    {
        fgets($stream, $length);
    }

fclose($stream);

?>
true
